Rare flavor-changing processes such as B→Ka decay offer sensitive probes of axion-like particles (ALPs) for masses below a few GeV. We study this process in the framework of QCD factorization and ALP effective theory, in which the ALP couples to the Standard Model fermions through shift-invariant derivative interactions. In contrast to previous studies, where flavor violation arises solely...

Many theoretical models predict that Dark Matter (DM) could interact weakly with the Standard Model (SM), thus be produced at the LHC. Many searches have been conducted by the ATLAS experiment to look for DM candidates in the final states with large missing transverse momentum produced in association with other SM particles (light and heavy quarks, leptons, photons, as well as additional heavy...
Scouting and cosmic-ray data extend CMS sensitivity into regions the standard trigger and analysis pipeline cannot reach. Scouting streams have enabled a growing suite of searches for physics beyond the Standard Model; we highlight recent results and new directions that pair them with modern machine-learning methods to expose signatures conventional approaches would miss. The cosmic stream in...
