In recent years there has been impressive progress in quark flavour physics, with current efforts tackling complicated quantities such as for example inclusive decays, decays to QCD-unstable final states and radiative decays. At the same time current lattice flavour physics results are receiving a lot of attention from outside the lattice community. This requires careful scrutiny,...
I will present a selection of recent results from the LHCb experiment, with a focus on topics that of interest at Lattice 2024. This will include highlights from the heavy flavour spectroscopy programme, with observations of new hadrons (both exotic and more standard in nature).
The last decade has seen an explosive growth of interest in exploiting developments in machine learning to accelerate lattice QCD calculations. On the sampling side, generative models are a promising approach to mitigating critical slowing down and topological freezing. Meanwhile, signal-to-noise problems have been shown to be improvable by the use of optimized improved observables. Both...
In this talk, I will review the physics context for and recent approaches to the inverse problem of spectral reconstruction.
The pillar for outreach in particle physics, which is nowadays an integral part of our work as researchers, is IPPOG, the International Particle Physics Outreach Group. IPPOG is a network of scientists, science educators and communication specialists working across the globe in informal science education and public engagement for particle physics. The flagship activity of IPPOG is the...
Hadron spectroscopy and the study of QCD resonances on the lattice has seen rapid advancements in recent years. This is thanks to new and refined analytical formalisms, improved computational strategies and last but not least a substantial community effort in pushing the boundaries to more complicated resonant channels and simulations at physical quark masses. In this talk I present a...
In order to study quantum field theories on a quantum computer we need to begin with lattice theories with a finite dimensional local Hilbert space. We view this as a new type of regularization of quantum field theories, and refer to it as qubit regularization, which can be explored both in Minkowski and Euclidean spaces. Such a finite dimensional regularization of a quantum field theory was...
I will give an overview on recent results on the QCD phase diagram at finite temperature and density.
Parton Distribution Functions (PDFs) are essential ingredients in realistic cross-section calculations within the framework of perturbative QCD. They describe the x-dependent structure of hadrons based on global analyses of hard-scattering measurements. PDFs play a crucial role in the search for new physics and precision measurements at hadron colliders, making the control of PDF uncertainties...
Recent advancements have facilitated the approximate computation of light-cone correlation functions in lattice QCD through the evaluation of their Euclidean counterparts. In this presentation, we will provide a brief overview of these significant developments and discuss their direct implications for Generalized Parton Distributions (GPDs). Additionally, we will highlight the importance of...
In our quest to uncover the secrets of hadrons, a groundbreaking tool emerges—the Electron Ion Collider (EIC). Set to be constructed at the Brookhaven National Laboratory, the EIC will be one of the world's largest and most advanced accelerator facilities. With unmatched resolving power and intensity, it acts as a powerful microscope, allowing us to explore how hadrons emerge from the...
From the early days of lattice QCD, hadron spectroscopy has been an integral part of it. With improved control over statistical and systematic errors, ground states of many hadrons are now very well determined by lattice QCD calculations. Significant progress has also been made in excited state calculations. These advancements, along with developments in amplitude analysis formalisms, have...
This talk summarises the explorations of theories beyond the Standard Model using lattice simulation methods. After a brief comment on the current status of the Standard Model extensions, the essential contribution made by numerical simulations in various approaches will be discussed. However, this also poses new challenges for simulation methods. The interplay with new theories gives rise to...
An update on glueball studies in lattice QCD and from some other methods is presented. The recent BES III announcement of a pseudoscalar glueball candidate is discussed.
Neutrinoless double-beta decay ($0\nu\beta\beta$) is a hypothesized decay mode of certain nuclear isotopes that, if observed, would demonstrate that neutrinos are their own antiparticles. Interpreting experimental measurements of $0\nu\beta\beta$ half-lives in terms of neutrino properties requires knowledge of the nuclear matrix elements encoding the hadronic physics involved in these decays....
We propose a simple instanton-based random matrix model of hot QCD that in the quenched case precisely reproduces the distribution of the lowest lattice overlap Dirac eigenvalues. Even after including dynamical quarks the model can be easily simulated in volumes and for quark masses that will be out of reach for direct lattice simulations in the foreseeable future. Our simulations show that...
