Minimal dark origin of a massless Dirac neutrino

P. S. Bhupal Dev, Julia Gehrlein, Amartya Sengupta +1

We propose a gauge-symmetry origin of a rank-two Dirac neutrino mass matrix that enforces one exactly massless neutrino, while being consistent with the oscillation data, as well a…

Amplitude-Based Analysis of QED Radiative Corrections to Electroproduction of -Mesons on Protons

Isabella Illari, Andrei Afanasev, William J. Briscoe +3

A formalism for radiative correction calculations in exclusive electroproduction on the proton is presented, extending the treatment developed for the pion channel. The EXCLURA…

Cavity, lumped-circuit, and spin-based detection of axion dark matter: differences and similarities

Deniz Aybas, Hendrik Bekker, Dmitry Budker +12

Axions and axion-like particles are compelling candidates for ultralight bosonic dark matter, forming coherent oscillating fields that can be probed by experiments known as halosco…

Bubble velocities in local equilibrium from a pseudopotential

Martin Münzenberg, Carlos Tamarit

We present a new method to estimate terminal bubble velocities during first-order phase transitions in a plasma in local equilibrium. The method relies on calculating the extrema o…

Impact of dim-6 SMEFT operators on low-scale leptogenesis

Kaori Fuyuto, Julia Harz, Sascha Weber

We investigate the impact of higher-dimensional operators on low-scale leptogenesis (LG) via oscillations of right-handed neutrinos within the neutrino-extended Standard Model Effe…

Dark-Matter-Enhanced Probe of Relic Neutrino Clustering

Writasree Maitra, Anna M. Suliga, Vedran Brdar +1

We propose heavy decaying dark matter (DM) as a new probe of the cosmic neutrino background (CB). Heavy DM, with mass GeV, decaying into neutrinos can be a new so…
