Charged Lepton Flavor Violation: A Theory Overview

We present a theory-oriented overview of the significance of charged-lepton flavor violation -- one of the cleanest windows onto physics beyond the Standard Model. We also summariz…
Resonant neutrino flavor conversion within dark matter spikes

Carlos A. Argüelles, Christopher V. Cappiello, P. S. Bhupal Dev +3
We show that keV thermal solar neutrinos, arising from electroweak processes in the solar plasma, are kinematically accessible to large-volume dark matter direct detection ex…
Probing Scalar Non-Standard Neutrino Interactions using High-Energy Astrophysical Neutrinos
Ankur Verma, Carlos A. Argüelles, P. S. Bhupal Dev +2
Scalar non-standard interaction (SNSI) of neutrinos contributes as modifications to the neutrino mass matrix in the oscillation Hamiltonian and can induce a small active-sterile ma…
Minimal dark origin of a massless Dirac neutrino

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…
Primordial Magnetogenesis and Gravitational Waves from ALP-assisted Phase Transition

Sufficiently strong first-order phase transitions (FOPTs) in the early Universe can simultaneously produce an observable stochastic gravitational wave background (SGWB) and a large…
