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. [...]

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. [...]
