 Handling photons in lattice QCD / Meyer, Harvey (speaker) (Johannes Gutenberg University Mainz)
I describe some of the computational challenges posed by handling photons in lattice QCD. In Euclidean space, amplitudes containing final-state photons are expressed in terms of hadronic correlation functions with a strong infrared weighting, which are hard to control. [...]

 Holography and Regge Phases at Large U(1) Charge / Fardelli, Giulia (speaker) (Boston U.)
We use holography to study the spectrum of multi-twist operators, within conformal field theories in d>2, in the large spin limit. Focusing on a CFT with a global U(1) current, we explore its phase diagram as a function of the U(1) charge Q and angular momentum J, particularly at large J and Q. [...]

 A new high-precision measurement of the B0 meson lifetime at the ATLAS experiment / Smizanska, Maria (speaker) (Lancaster University (GB))
The seminar presents a new high-precision measurement of the B0 effective lifetime in B0 to J/psi K*0 decays, using 140 fb-1 of 13 TeV pp collision data recorded by the ATLAS detector. Results for the average decay width, Gamma_d, and the width ratio Gamma_d/Gamma_s are also reported [...]

 2D Gauge Theories on the Hamiltonian Lattice / Dempsey, Ross (speaker) (Princeton)
Lately there has been renewed interest in two-dimensional gauge theories, stemming from their applicability as toy models of QCD along with rapidly advancing techniques for simulating them both numerically and experimentally. I will start by discussing the U(1) theory coupled to a fermion in two dimensions, and important lessons from its ABJ anomaly that can be used to dramatically improve the accuracy of results obtained from the Hamiltonian lattice [...]
