Renormalisation group evolution of the shape function $g_{17}$ in $\bar{B}\to X_s \gamma$ and $\bar{B} \to X_s \ell^+\ell^-$ at subleading power / Bartocci, Riccardo (U. Mainz, PRISMA ; Mainz U., Inst. Phys.) ; Böer, Philipp (CERN) ; Hurth, Tobias (U. Mainz, PRISMA ; Mainz U., Inst. Phys.)
We derive and solve the renormalisation-group (RG) equation of the shape function $g_{17}(\omega,\omega_1;\mu)$, which appears at subleading power in the factorization of the inclusive decays $\bar{B} \to X_s \gamma$ and $\bar B \to X_s \ell^+\ell^-$. [...]

Bounds on the bubble wall velocity / Ai, Wen-Yuan (King's Coll. London) ; Laurent, Benoit (McGill U., Montreal (main)) ; van de Vis, Jorinde (CERN)
Determining the bubble wall velocity in first-order phase transitions is a challenging task, requiring the solution of (coupled) equations of motion for the scalar field and Boltzmann equations for the particles in the plasma. [...]

The two-loop fully differential soft function for $Q\bar{Q}V$ production at lepton colliders / Liu, Ze Long (Beijing, Inst. High Energy Phys.) ; Monni, Pier Francesco (CERN)
We consider the production of a pair of heavy quarks $Q\bar{Q}$ in association with a generic colour singlet system $V$ at lepton colliders, and present the first analytic calculation of the two-loop soft function differential in the total momentum of the real radiation. [...]

A Cell Resampler study of Negative Weights in Multi-jet Merged Samples / Andersen, Jeppe R. (Durham U. (main) ; CERN) ; Cueto, Ana (U. Autonoma, Madrid (main)) ; Jones, Stephen P. (Durham U. (main)) ; Maier, Andreas (Barcelona, IFAE ; Barcelona, Autonoma U.)
We study the use of cell resampling to reduce the fraction of negatively weighted Monte Carlo events in a generated sample typical of that used in experimental analyses. [...]

Strange and charm quark contributions to the muon anomalous magnetic moment in lattice QCD with twisted-mass fermions / Extended Twisted Mass Collaboration (ETMC) Collaboration
We present a lattice calculation of the Hadronic Vacuum Polarization (HVP) contribution of the strange and charm quarks to the anomalous magnetic moment of the muon in isospin symmetric QCD. [...]

We present our lattice QCD result for the long-distance part of the hadronic vacuum polarization contribution, $(a_\mu^{\rm hvp})^{\rm LD}$, to the muon $g-2$ in the time-momentum representation. [...]

Combination of aN$^3$LO PDFs and implications for Higgs production cross-sections at the LHC / MSHT Collaboration
We discuss how the two existing approximate N$^3$LO (aN$^3$LO) sets of parton distributions (PDFs) from the MSHT20 and NNPDF4.0 series can be combined for LHC phenomenology, both in the pure QCD case and for the QCD$\otimes$QED sets that include the photon PDF. [...]
