Reappraisal of the Constraints on Heavy Axion-like Particles from Gamma-Ray Bursts
Christopher V. Cappiello, Saurav Das, P. S. Bhupal Dev +2
We reassess existing limits and derive new constraints on heavy axion-like particle (ALP) coupling to photons using gamma-ray bursts (GRBs). ALPs can be produced in the hot dense f…
Probing Scalar Non-Standard Neutrino Interactions using High-Energy Astrophysical Neutrinos
Ankur Verma, Carlos A. Argüelles, Carlos A. Argüelles +3
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…
Charged Lepton Flavor Violation at Neutrino Telescopes
Writasree Maitra, Carlos A. Argüelles, P. S. Bhupal Dev +2
Any observation of charged lepton flavor violation (CLFV) would be a clear signal of beyond-the-Standard-Model physics. Here, we propose a novel CLFV search using neutrino telescop…
Towards the Detection of Thermal Solar Neutrinos
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…
