DESCRIPTION:Speakers: Andrew Cheek (Institute of Particle Physics Phenomen
ology)\nA new generation of Direct Detection Experiments are now running\,
and with an ever increasing number of Dark Matter particle models\, it is
important to interpret new data agnostically. The Non-Relativistic Effect
ive Field Theory approach is particularly well suited to this task\, and e
ncapsulates behaviour of elastic scattering in DD Experiments in a very ge
neral way.\n\nIn this talk I will look at recent efforts to distinguish ju
st how much information about the particle nature of DM we can glean from
DD experiments.\n\nhttps://conference.ippp.dur.ac.uk/event/560/contributio

DESCRIPTION:Speakers: Ben Meiring (University of Oxford)\nDue to a corresp
ondence between Hydrodynamics and Gravity\, one can study a fluid-like Qua
rk-Gluon Plasma (QGP) at infinite coupling through perturbations of a boos
ted blackbrane solution in General Relativity.\n\nIn previous work the lat
e time expansion of Bjorken flow (1-dimensional\, boost-invariant flow as
present during Heavy Ion collisions) was computed in a gradient expansion
to high orders and the technique of Resurgence was used to understand the
emergence of non-hydrodynamic modes in the structure of large order pertur
bation.\n\nAs a first step towards understanding finite coupling correctio
ns to the non-hydrodynamic behavior of the QGP\, we will extend this metho
d in Gauss-Bonnet Gravity\, a higher derivative extension of Einstein grav
ity.\n\nhttps://conference.ippp.dur.ac.uk/event/560/contributions/3267/

ding fixed points is a difficult problem in general as one has an infinite
number of couplings to deal with. In this talk I will discuss how restric
ting to the case of weakly coupled four-dimensional gauge theories allows
for a complete classification of the types of fixed points which are possi
ble\, and the role Yukawa couplings play in offering a unique mechanism to
allow such non-trivial fixed points to be ultraviolet.\n\nhttps://confere

d as alternatives to spontaneous electroweak symmetry breaking. Today\, Wa
lking Technicolor theory offers both a solution to the hierarchy problem\,
a Higgs boson-like particle corresponding to observation\, and a rich phe
nomenology which we can explore within the current energy capabilities of
the LHC. We explore signals of new neutral resonances in WTC at the LHC\,
to give the strongest constraints on WTC to date\, and possibly to determi
ne the future of Technicolor theory and strong dynamics.\n\nhttps://confer

DESCRIPTION:Speakers: Nicholas Jennings (University of Oxford)\nAn excess
of X-Rays at 3.5 keV detected in various galaxies and clusters\, including
the Perseus cluster\, has generated a lot of excitement as a potential Da
rk Matter signal. Hitomi observations of Perseus with the Soft X-ray Spect
rometer (SXS) provide a high-resolution look at the 3.5 keV feature. The H
itomi spectrum -- which involves the sum of diffuse cluster emission and t
he point-like central Active Galactic Nucleus (AGN) -- does not show any e
xcess at E ~ 3.5keV\, giving an apparent inconsistency with previous obser
vations of excess diffuse emission. We point out that 2009 Chandra data re
veals a strong dip in the AGN spectrum at E = (3.54 ± 0.02) keV (cluster
frame) -- the identical energy to the diffuse excess observed by XMM-Newto
n. Scaling this dip to the 2016 AGN luminosity and adding it to the diffus
e XMM-Newton excess\, this predicts an overall dip in the SXS field of vie
w of (-7.7 ± 4.6) x 10-6 ph cm^-2 s^-1 at E = 3.54 keV\, a precise match
to the Hitomi data when broadened by the dark matter virial velocity. We d
escribe models of Fluorescent Dark Matter that can reproduce this physics\
, in which dark matter absorbs and then re-emits 3.5 keV photons emitted f
rom the central AGN.\n\nhttps://conference.ippp.dur.ac.uk/event/560/contri

DESCRIPTION:Speakers: Scott Melville (Imperial College London)\nMany quant
um field theories are only well-defined at low energies - with a breakdown
of unitarity above some energy cutoff. If there is a physically sensible
way to introduce new degrees of freedom which restore unitarity\, then thi
s apparent breakdown needn't worry us - we say that the original theory ad
mits a *UV completion*. However\, if it is **not** possible to UV complete
the theory\, this is very troublesome - it means that the original low en
ergy theory cannot describe a reality which is consistent with QFT's axiom
s (i.e. our Universe). So it is of great importance to establish whether o
ur favourite QFTs (whatever they may be) can have UV completions. In this
talk I will present some conditions which any low energy effective field t
heory ought to satisfy in order to have a standard UV completion\, and dis
cuss the particular example of massive gravity.\n\nhttps://conference.ippp

DESCRIPTION:Speakers: Patrick Tunney (King's College London)\nSearches for
Dark Matter (DM) at the LHC using effective field theory can be unreliabl
e as we cannot guarantee the cut-off in such theories is above the typical
energy involved in a LHC collision. Therefore a set of simplified models
are typically used to interpret LHC data\, with a dynamical mediator prese
nt in the model that is responsible for the interactions between the dark
and visible sectors. Direct searches for such mediators then complement mo
re traditional missing energy signatures of DM. \n\nDijets are a good exam
ple of this and I will present a recasting of dijet data in terms of a spi
n-one mediator coupling to quarks (a leptophobic Z') in a reasonably gener
al and model independent way. I will then show a novel way of combining th
ese bounds with the requirement that the theory accounts for all the DM in
the universe today.\n\nhttps://conference.ippp.dur.ac.uk/event/560/contri

particle production.\n\nI am going to present the production of a field wi
th no coupling to any other field\, the only possible way of interaction w

present in this model and I will show how to deal with them and how to ob

DESCRIPTION:Speakers: Nick Prouse (Southampton & Queen Mary University of
London)\nWe present a study into the extent that upcoming precision neutri
no oscillation experiments will exclude one of the most predictive models
of neutrino mass and mixing: the Littlest Seesaw. This model provides a go
od fit to current data\, predicting eight observables from two input param
eters\, and provide new assessments of its predictions and their correlati
ons. The ability to exclude this model is assessed using simulations of up
coming neutrino oscillation experiments including the medium-distance reac
tor experiments JUNO and RENO-50 and the long-baseline accelerator experim
ents DUNE and T2HK. We show that an accurate determination of the currentl
y least well measured parameters\, namely the atmospheric and solar angles
and the CP phase $\\delta$\, provide crucial independent tests of the mod
el. For $\\theta_{13}$ and the two mass-squared differences\, however\, th
e model's exclusion requires a combination of measurements coming from a v
aried experimental programme. These results show that the synergy and comp
lementarity of future experiments will play a vital role in efficiently di
scriminating between predictive models of neutrino flavour\, and hence\, t
owards advancing our understanding of neutrino oscillations in the context
of the flavour puzzle of the Standard Model.\n\nhttps://conference.ippp.d

DESCRIPTION:Speakers: Ibles Olcina (United Kingdom: Imperial College Londo
n\, South Kensington campus)\nOne of the major challenges of modern physic
s is to discover the nature of dark matter\, an invisible and dominant mas
s component of the observable universe that is indirectly revealed through
its gravitational effects on ordinary matter. Assuming that dark matter i
s made of new elementary particles\, a well-motivated and generic class of
dark matter candidates are weakly interacting massive particles (WIMPs)\,
which arise naturally in several extensions to the Standard Model. WIMPs
could be directly detected via their scattering off atomic nuclei in under
ground\, ultra low-background detectors. In this report\, an overview of t
he dark matter direct detection LZ experiment is given\, which originates
from the merging of the successful ZEPLIN experiments in the UK and LUX ex
periment in the US. With its 7 tonnes of active liquid xenon\, it is expec
ted that the LZ experiment will probe WIMP interactions practically as far
as it is allowed by new backgrounds from astrophysical neutrinos.\n\nhttp

of these events when the orientation of the polarization axis is antipara
llel to the direction of the Sun. We comment on the possible improvement i

DESCRIPTION:Speakers: Ben Geytenbeek (University of Cambridge)\nIn recent
years\, a revised set of solar abundances has led to a discrepancy in the
sound-speed profile between helioseismology and theoretical solar models.
Conventional solutions require additional mechanisms for energy transport
within the Sun. Vincent et al. have recently suggested that dark matter wi
th a momentum or velocity dependent cross section could provide a solution
. In this work\, we consider three models of dark matter with such cross s
ections and their effect on the stellar structure. In particular\, the thr
ee models incorporate dark matter particles interacting through an electro
magnetic dipole moment: an electric dipole\, a magnetic dipole or an anapo
le. Each model is implemented in the DarkStec stellar evolution program\,
which incorporates the effects of dark matter capture and heat transport w
ithin the solar interior. We show that dark matter with a mass of 3 GeV an
d an electric dipole moment or an anapole moment of may possibly improve t
he sound-speed profile\, small frequency separations and convective zone r
adius with respect to the Standard Solar Model. However\, the required dip
ole moments are strongly excluded by direct detection experiments.\n\nhttp

DESCRIPTION:Speakers: Lukas Graf (University College London)\nIn my talk I
will describe the effective approach to lepton number violation and impli
cations of potential future observation of lepton number violating (LNV) p
rocesses\, primarily of neutrinoless double beta decay. The interplay betw
een lepton number violation at high and low energies is of particular inte
rest\, as the constraints on theories of baryogenesis can be obtained. One
can state that if neutrinoless double beta decay is trigerred by other th
an the standard mass mechanism\, then the usual high-scale baryogenesis mo
dels will be excluded. As can be shown\, each LNV effective operator contr
ibutes to neutrinoless double beta decay in a number of ways and the under
standing of the mutual relations among all the operators is crucial when d
etermining the dominant contribution. Moreover\, the nuclear side of the p
roblem plays an important role\, as a thorough calculation of correspondin
g nuclear matrix elements is needed for the estimation of the effective co
uplings and it can also help to pinpoint the dominant mechanism triggering
neutrinoless double beta decay. Apart from the effective field approach\,
I will also outline the possible extension of our arguments to a general
UV-completed model.\n\nhttps://conference.ippp.dur.ac.uk/event/560/contrib
