Beyond standard model particles in the atmospheric flux: a long-lived stau example
Atri Bhattacharya, Mary Hall Reno, Ina Sarcevic
We discuss fluxes of long-lived supersymmetric (SUSY) particles produced in the atmosphere from ultra-high energy cosmic-ray interactions with air nuclei. We consider long-lived pa…
Perturbative Charm Production and the Prompt Atmospheric Neutrino Flux in light of RHIC and LHC
Atri Bhattacharya, Rikard Enberg, Mary Hall Reno +2
Prompt neutrinos due to the decay of charmed mesons produced in the atmosphere from cosmic-ray and atmospheric nuclei interactions may be a significant source of background to ultr…
The proton inelastic cross section at ultrahigh energies
Atri Bhattacharya, Jean-René Cudell, Rami Oueslati +1
We study the consequences of high-energy collider data on the best fits to total, elastic, and inelastic cross sections for and scattering using two very distinct u…
Probing decaying heavy dark matter with the 4-year IceCube HESE data
Atri Bhattacharya, Arman Esmaili, Sergio Palomares-Ruiz +1
After the first four years of data taking, the IceCube neutrino telescope has observed 54 high-energy starting events (HESE) with deposited energies between 20 TeV and 2 PeV. The b…
Perturbative charm production and the prompt atmospheric neutrino flux in light of RHIC and LHC
Atri Bhattacharya, Rikard Enberg, Mary Hall Reno +2
We re-evaluate the prompt atmospheric neutrino flux, using the measured charm cross sections at RHIC and the Large Hadron Collider to constrain perturbative QCD parameters such as…
On the interpretation of IceCube cascade events in terms of the Glashow resonance
Atri Bhattacharya, Raj Gandhi, Werner Rodejohann +1
The IceCube experiment (IC) has recently observed 2 cascade events with energies between 1 and 10 PeV. This energy combined with the fact that no muon-track events are observed may…
