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…
Galactic Center Neutrinos from Cosmic Ray-Dark Matter Interactions
Jorge Terol Calvo, Pedro de la Torre Luque, Mainak Mukhopadhyay +2
The IceCube and ANTARES collaborations have recently reported evidence for high-energy neutrinos associated with the Galactic plane and the Galactic Ridge, offering a new pathway t…
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…
New Supernova Constraints on Neutrinophilic Dark Sector - Vector Mediators
Christopher V. Cappiello, P. S. Bhupal Dev, Amol V. Patwardhan
Supernova cooling has long been used to constrain physics beyond the Standard Model, typically involving new mediators or dark matter (DM) particles that couple to nucleons or elec…
Deconstructive Composite Dark Matter Detection
Yilda Boukhtouchen, Joseph Bramante, Christopher Cappiello +1
We investigate the detection of composite dark matter that disassembles into a cascade while crossing the Earth. This occurs for loosely bound composite dark matter, where the bind…
Can a Dark Inferno Melt Earth's Core?
Christopher Cappiello, Tansu Daylan
The search for dark matter is one of the crucial open problems in both particle physics and cosmology. If dark matter scatters with Standard Model particles, it could accumulate in…
