Factorization at Next-to-Leading Power and Endpoint Divergences in $gg\to h$ Production / Liu, Ze Long (CERN) ; Neubert, Matthias (Mainz U., Inst. Phys. ; U. Mainz, PRISMA ; Cornell U., LEPP ; Cornell U., Phys. Dept.) ; Schnubel, Marvin (U. Mainz, PRISMA ; Mainz U., Inst. Phys.) ; Wang, Xing (Munich, Tech. U. ; ORIGINS, Garching)
We derive a factorization theorem for the Higgs-boson production amplitude in gluon-gluon fusion induced by a light-quark loop, working at next-to-leading power in soft-collinear effective theory. The factorization is structurally similar to that obtained for the $h\to\gamma\gamma$ decay amplitude induced by a light-quark loop, but additional complications arise because of external color charges.

New Physics Searches at Kaon and Hyperon Factories / Goudzovski, Evgueni (Birmingham U.) ; Redigolo, Diego (CERN ; INFN, Florence) ; Tobioka, Kohsaku (Florida State U. ; KEK, Tsukuba) ; Zupan, Jure (Cincinnati U.) ; Alonso-Álvarez, Gonzalo (McGill U.) ; Alves, Daniele S.M. (Los Alamos) ; Bansal, Saurabh (Cincinnati U.) ; Bauer, Martin (Durham U., ICC) ; Brod, Joachim (Cincinnati U.) ; Chobanova, Veronika (Santiago de Compostela U., IGFAE) et al.
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths and the availability of very large datasets. [...]

Flavor probes of axion-like particles / Bauer, Martin (Durham U., IPPP) ; Neubert, Matthias (Mainz U., Inst. Phys. ; U. Mainz, PRISMA ; Cornell U., LEPP) ; Renner, Sophie (SISSA, Trieste ; INFN, Trieste ; CERN) ; Schnubel, Marvin (Mainz U., Inst. Phys. ; U. Mainz, PRISMA) ; Thamm, Andrea (Melbourne U.)
Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-energy extensions of the Standard Model (SM). We investigate the phenomenology of an ALP with flavor-changing couplings, and present a comprehensive analysis of quark and lepton flavor-changing observables within a general ALP effective field theory.

Axionlike Particles, Lepton-Flavor Violation, and a New Explanation of $a_\mu$ and $a_e$ / Bauer, Martin (Durham U., IPPP) ; Neubert, Matthias (U. Mainz, PRISMA ; Cornell U., LEPP ; Cornell U.) ; Renner, Sophie (U. Mainz, PRISMA) ; Schnubel, Marvin (U. Mainz, PRISMA) ; Thamm, Andrea (CERN)
Axion-like particles (ALPs) with lepton-flavor violating couplings can be probed in exotic muon and tau decays. The sensitivity of different experiments depends strongly on the ALP mass and its couplings to leptons and photons. [...]
