DESCRIPTION:Speakers: Simon King (University of Southampton)\nWe study and
compare various Zmodels arising from SO(10)\, focussing in particular on
the Abelian subgroup U(1)R × U(1)B−L\, broken at the TeV scale to Stand
ard Model hypercharge U(1)Y. The gauge group U(1)R × U(1)B−L\, which is
equivalent to the U(1)Y × U(1)χ in a different basis\, is well motivate
d from SO(10) breaking and allows neutrino mass via the linear seesaw mech
anism. Assuming supersymmetry\, we consider single step gauge unification
to predict the gauge couplings\, then consider the detection and character
isation prospects of the resulting Zat the LHC by studying its possible de
cay modes into dileptons as well as into Higgs bosons. The main new result
here is to analyse in detail the expected leptonic forward-backward asymm
etry at the high luminosity LHC and show that it may be used to discrimina
te the U(1)R ×U(1)B−L model from the usual B −L model based on U(1)Y
×U(1)B−L.\n\nhttps://conference.ippp.dur.ac.uk/event/825/contributions/

reduces to 11d supergravity at low energies. Higher-derivative corrections
to tree-level supergravity are encoded in the anomalous dimensions of dou

Moschella have shown that anti-periodic real scalar fields have no analogu
e of a Bunch-Davies vacuum state. For complex scalar fields\, more general
behaviour is possible. I will discuss complex scalar field theories in tw

In this talk I focus on one approach to formulate out-of-equilibrium QFT
using the N-PI effective action\, a natural extension of the 1PI effective
action\, within the Keldysh formalism. Explicitly considering the 2PI app

pics\, as this framework finds applications across scales. Some of these a

In certain BSM theories such a transition can occur via a first order pha

Such a source would form a stochastic background observable with the upco

DESCRIPTION:Speakers: Amy Lloyd-Stubbs (Lancaster University)\nWe discuss
a model of inflation with a minimal Image potential. There are two main pr
oblems with conventional Image chaotic inflation: the tensor to scalar rat
io is generally unacceptably large\, and it requires a super-Planckian inf
laton field in order to inflate. It has been shown recently that a minimal
Image inflation model with an Image term in the context of Palatini gravi
ty is able to solve the problem of a large tensor to scalar ratio while ma
intaining the successful prediction of the scalar spectral index. In this
work we seek to answer the following questions: can the inflaton in this m
odel remain sub-Planckian and remain consistent for Planck-suppressed pote
ntial corrections\, and can this model produce a viable post-inflation cos
mology? We show that for large enough values of the dimensionless coupling
alpha on the Image term\, it is possible for the relevant inflaton in the
Einstein frame to be sub-Planckian and for the scalar spectral index to b
e unaffected by Planck-suppressed potential corrections. In addition\, we
show that the reheating temperature is large enough for a viable post-infl
ation cosmology\, and that the model conserves unitarity during inflation.
We discuss some specific reheating mechanisms and the evolution of the in
flaton field after inflation\, including the possibility of condensate fra
gmentation.\n\nhttps://conference.ippp.dur.ac.uk/event/825/contributions/4

DESCRIPTION:Speakers: Philip Glass (Durham University)\nFinding a non-pert
urbative formulation of Quantum Field Theory (QFT) is an important outstan
ding problem in physics and mathematics. In mathematics it is needed to pu
t QFT on rigorous footing. In physics it is needed to explain many phenome
na observed in nature\, particularly at strong coupling\, for example the
confinement of quarks. Resurgence and Picard-Lefschetz theory are tools th
at provide a way of calculating non-perturbative contributions from pertur
bative ones\, and thus look like a promising route to unravelling some of
the mysteries of non-perturbative QFT. Resurgence does this through analys
ing asymptotic series. Picard-Lefschetz gives a complementing picture from
a path-integral perspective. I will give an introductory talk to one or b
oth of these topics\, with some basic examples\, to give a flavour of how
they work.\n\nhttps://conference.ippp.dur.ac.uk/event/825/contributions/47

DESCRIPTION:Speakers: Kieran Finn (University of Manchester)\nThe laws of
physics should not depend on how we choose to describe them\, and we shoul
d not be able to change the physical predictions of our theory just by cha
nging notation. However\, this is exactly what happens in the standard for
mulation of quantum field theories. The effective action receives differen
t quantum corrections depending on how we parametrise our fields. Even Fey
nman diagrams\, a fundamental building block for QFT calculations\, yield
results that depend on the definition of the fields we choose to work with
. In this talk I will rectify these problems by introducing the notion of
grand covariance\, in which the quantum fields are treated as coordinates
on a manifold\, known as the grand field space. Field redefinitions are th
en simply diffeomorphisms of this manifold and thus we can impose reparame
trisation invariance using well-known techniques from differential geometr
y. I show how we can apply this formalism to scalar-tensor theories of qua
ntum gravity. This talk is based on arXiv:1910.06661.\n\nhttps://conferenc

DESCRIPTION:Speakers: Matthew Kellett (University of Southampton)\nIn this
talk\, we take inspiration from studies of using SU(N|N) to construct a m
anifestly gauge invariant renormalisation procedure and attempt to apply t
his to gravity\, preserving diffeomorphism invariance and incorporating al
lowing us to fit gravity into the renormalisation group (a rather well-kno
wn problem in physics). This means introducing a supermanifold and attempt
ing to find the degrees of freedom by looking at the second order action.\
n\nFor this to work like gauge theory\, we are required to break the super
symmetry and be left with the normal diffeomorphism invariance. Fortunatel
y\, a mass very naturally appears in the superfield formalism\, however we
find that it doesn't act like a mass at the level of the propagator. None
theless\, we find many interesting and useful results about gravity on a s
upermanifold and offer ways which this approach may yet work.\n\nhttps://c

SUMMARY:Leptoquark Pair Production at Future Colliders

DESCRIPTION:Speakers: Maeve Madigan (University of Cambridge)\nAs new phys
ics continues to evade detection at the LHC\, proposals have been made for
future colliders with the aim of extending the mass reach and improving s
ensitivity to physics beyond the standard model. The scalar leptoquark pr
ovides a particularly interesting new physics candidate. At tree-level\,
leptoquark-mediated transitions may account for the hints at lepton flavou
r universality violation observed by experiments such as Belle and LHCb.
I will present estimates of the sensitivity of the high luminosity and hig
h energy modes of the LHC and of a 100 TeV future circular collider to the
se leptoquarks\, focusing on their pair production and decay into the dimu
on dijet channel.\n\nhttps://conference.ippp.dur.ac.uk/event/825/contribut

DESCRIPTION:Speakers: Sam Rowley (University of Southampton)\nWe consider
a simple renormalisable and gauge-invariant model in which a massive new Z
′ boson has couplings only to the electron and muon and their associated
neutrinos\, arising from mixing with a heavy vector-like fourth family of
leptons. Within this model\, we discuss the contributions to the electron
and muon anomalous magnetic moments from Z′ exchange\, subject to the c
onstraints from μ→eγ and neutrino trident production. Using analytic a
nd numerical arguments\, we find that such a Z′ model can account for ei
ther the electron or the muon g−2 anomalies while remaining consistent w
ith the experimental constraints from μ→eγ and neutrino trident produc
tion\, but not both simultaneously.\n\nhttps://conference.ippp.dur.ac.uk/e
