Large-x resummation of off-diagonal deep-inelastic parton scattering from d-dimensional refactorization / Beneke, Martin ; Garny, Mathias ; Jaskiewicz, Sebastian ; Szafron, Robert ; Vernazza, Leonardo ; Wang, Jian
The off-diagonal parton-scattering channels $g+\gamma^*$ and $q+\phi^*$ in deep-inelastic scattering are power-suppressed near threshold $x\to 1$. [...]

Probing New Physics in Dimension-8 Neutral Gauge Couplings at $e^+e^-$ Colliders / Ellis, John ; He, Hong-Jian ; Xiao, Rui-Qing
Neutral triple gauge couplings (nTGCs) are absent in the standard model effective theory up to dimension-6 operators, but could arise from dimension-8 effective operators. [...]

From Ji to Jaffe-Manohar orbital angular momentum in Lattice QCD using a direct derivative method / Engelhardt, M. (New Mexico State U.) ; Green, J.R. (CERN) ; Hasan, N. (Bergische U., Wuppertal (main)) ; Krieg, S. (Bergische U., Wuppertal (main) ; IAS, Julich) ; Meinel, S. (Arizona U.) ; Negele, J. (MIT, Cambridge, CTP) ; Pochinsky, A. (MIT, Cambridge, CTP) ; Syritsyn, S. (RIKEN BNL ; SUNY, Stony Brook)
A Lattice QCD approach to quark orbital angular momentum in the proton based on generalized transverse momentum-dependent parton distributions (GTMDs) is enhanced methodologically by incorporating a direct derivative technique. [...]

Correlating $h\to\mu^+\mu^-$ to the Anomalous Magnetic Moment of the Muon via Leptoquarks / Crivellin, Andreas ; Mueller, Dario ; Saturnino, Francesco
Recently, both ATLAS and CMS measured the decay $h\to\mu^+\mu^-$, finding a signal strength with respect to the Standard Model (SM) expectation of $1.2\pm0.6$ and $1.19\substack{+0.41+0.17\\-0.39 -0.16}$, respectively. [...]

Combining single and double parton scatterings in a parton shower / Cabouat, Baptiste ; Gaunt, Jonathan R.
Double parton scattering (DPS) processes in which there is a perturbative \mbox{``$1\to2$''} splitting in both protons overlap with loop corrections to single parton scattering (SPS). [...]

Global Electroweak Fit and Vector-Like Leptons in Light of the Cabibbo Angle Anomaly / Crivellin, Andreas ; Kirk, Fiona ; Manzari, Claudio Andrea ; Montull, Marc
The "Cabibbo Angle Anomaly'' (CAA) originates from the disagreement between the CKM elements $V_{ud}$ and $V_{us}$ extracted from superallowed beta and kaon decays, respectively, once compared via CKM unitarity. [...]

Updated predictions for gravitational waves produced in a strongly supercooled phase transition / Ellis, John ; Lewicki, Marek ; Vaskonen, Ville
We update predictions for the gravitational wave (GW) signal from a strongly supercooled phase transition in an illustrative classically conformal U(1)$_{B-L}$ model. [...]

The Neutrino Magnetic Moment Portal: Cosmology, Astrophysics, and Direct Detection / Brdar, Vedran ; Greljo, Admir ; Kopp, Joachim ; Opferkuch, Toby
We revisit the physics of neutrino magnetic moments, focusing in particular on the case where the right-handed, or sterile, neutrinos are heavier (up to several MeV) than the left-handed Standard Model neutrinos. [...]
