Non-Thermal Production of Sexaquark Dark Matter

Marianne Moore, Stefano Profumo

Standard thermal freeze-out scenarios with QCD-scale interaction rates predict a sexaquark relic abundance many orders of magnitude below the observed dark matter density,…

Structure Formation with Dark Magnetohydrodynamics

Pierce Giffin, Andrew Liu, Jeremias Boucsein +4

Long-range interactions in the dark sector can give rise to collective plasma phenomena that are capable of modifying the evolution of dark matter halos. We present the first study…

Lepton Flavor Violation: From Muon Decays to Muon Colliders

Pouya Asadi, Hengameh Bagherian, Katherine Fraser +2

We investigate the unique potential of a high-energy muon collider to probe lepton-flavor-violating signals arising from physics beyond the Standard Model (SM). Low-energy, precisi…

Sweeping the pion chimney for axion-like particles with KOTO

Reuven Balkin, Stefania Gori, Dean J. Robinson +1

We demonstrate that novel limits on prompt axion-like particles (ALPs) in the hard-to-probe mass range near the neutral pion - the so-called pion chimney - may be obtained from rec…

Updated Constraints from Electric Dipole Moments in the MSSM with R-Parity Violation

Wolfgang Altmannshofer, P. S. Bhupal Dev, Amarjit Soni +1

We revisit the electric dipole moments (EDMs) of quarks and leptons in the Minimal Supersymmetric Standard Model (MSSM) with trilinear -parity violation (RPV). In this framework…

The Cosmic Horizon of Neutrinos

James Fardeen, Stefano Profumo, M. Grant Roberts

The persistent discrepancy between the experimental measurement and the Standard Model (SM) prediction of the muon's anomalous magnetic moment remains one of the most int…
