Enhanced active-sterile neutrino polarizability at the intensity frontier
Julia Gehrlein, Anil Thapa, Adrian Thompson
Electromagnetic probes of neutrinos can provide insights into physics beyond the Standard Model. Among the possible electromagnetic interactions of neutrinos is neutrino polarizabi…

Kaon decay constraints on vector bosons coupled to non-conserved currents
Matheus Hostert, Maxim Pospelov, Adrian Thompson
We study rare three- and four-body kaon decays as a probe of light vector and axial-vector bosons coupled to non-conserved currents. We find that searches for $K_L \to Ï^0 Ï^0 (X…

Baryon Number Violation: From Nuclear Matrix Elements to BSM Physics
Leah J. Broussard, Andreas Crivellin, Martin Hoferichter +19
Processes that violate baryon number, most notably proton decay and transitions, are promising probes of physics beyond the Standard Model (BSM) needed to understand the…
