Master-field simulations of QCD / Fritzsch, P. ; Bulava, J. ; Cè, M. ; Francis, A. ; Lüscher, M. ; Rago, A.
We report on the first master-field simulations of QCD with 2+1 dynamical quark flavours using non-perturbatively improved stabilised Wilson fermions. [...]

Likelihood analysis of the flavour anomalies and $g-2$ in the general two Higgs doublet model / Athron, Peter (Nanjing Normal U. ; Monash U.) ; Balazs, Csaba ; Gonzalo, Tomás E. ; Jacob, Douglas ; Mahmoudi, Farvah ; Sierra, Cristian
We present a likelihood analysis of the general two Higgs doublet model, using the most important currently measured flavour observables, in view of the anomalies in charged current tree-level and neutral current one-loop rare decays of $B$ mesons in $b\to c l \overline{\nu}$ and $b\to s\mu^{+}\mu^{-}$ transitions, respectively.

Vacuum correlators at short distances from lattice QCD / Harris, Tim ; Cè, Marco ; Meyer, Harvey B. ; Toniato, Arianna ; Török, Csaba
We propose a method to help control cutoff effects in the short-distance contribution to integrated correlation functions, such as the hadronic vacuum polarization (HVP), using the corresponding screening correlators computed at finite temperature. The strategy is investigated with Wilson fermions at leading order, which reveals a logarithmically-enhanced lattice artifact in the short-distance contribution, whose coefficient is determined at this order.

Yoga Dark Energy: Natural Relaxation and Other Dark Implications of a Supersymmetric Gravity Sector / Burgess, C.P. (McMaster U. ; Perimeter Inst. Theor. Phys. ; CERN) ; Dineen, Danielle (McMaster U.) ; Quevedo, F. (Cambridge U., DAMTP)
We construct a class of 4D `yoga' (naturally relaxed) models for which the vacuum energies of heavy particles do not gravitate. [...]

Efficient Representation for Simulating U(1) Gauge Theories on Digital Quantum Computers at All Values of the Coupling / Bauer, Christian W. ; Grabowska, Dorota M.
We derive a representation for a lattice U(1) gauge theory with exponential convergence in the number of states used to represent each lattice site that is applicable at all values of the coupling. [...]

Generalized Spectral Form Factors and the Statistics of Heavy Operators / Belin, Alexandre (CERN ; Amsterdam U.) ; de Boer, Jan ; Nayak, Pranjal (Geneva U., Dept. Theor. Phys.) ; Sonner, Julian (Geneva U., Dept. Theor. Phys.)
The spectral form factor is a powerful probe of quantum chaos that diagnoses the statistics of energy levels, but is blind to other features of a theory such as matrix elements of operators or OPE coefficients in conformal field theories. [...]
