Probing the anomalous positron fraction origin with fully leptonic decaying gravitino dark matter candidates
Johannes Buchner, Edson Carquin, Marco A. Díaz +3
The flux of electron and positron cosmic rays measured by the space-based experiments PAMELA, AMS-02, CALET, DAMPE and Fermi-LAT shows an unexpected behaviour at high energies, in…
Seeking leptoquarks in IceCube
Damir Bečirević, Boris Panes, Olcyr Sumensari +1
We investigate the sensitivity of IceCube(-Gen2) to a scalar leptoquark scenario with couplings only to heavy quark flavors which may be connected to solving discrepancies in -m…
How Unequal Fluxes of High Energy Astrophysical Neutrinos and Antineutrinos can Fake New Physics
Hiroshi Nunokawa, Boris Panes, Renata Zukanovich Funchal
Flavor ratios of very high energy astrophysical neutrinos, which can be studied at the Earth by a neutrino telescope such as IceCube, can serve to diagnose their production mechani…
Confronting recent AMS-02 positron fraction and Fermi-LAT Extragalactic Gamma-Ray Background measurements with gravitino dark matter
Edson Carquin, Marco A. Diaz, German A. Gomez-Vargas +2
Recent positron flux fraction measurements in cosmic-rays (CR) made by the AMS-02 satellite confirm and extends the evidence on the existence of a new (yet unknown) source of high…
Possible Interpretations of IceCube High-Energy Neutrino Events
Chee Sheng Fong, Hisakazu Minakata, Boris Panes +1
We discuss possible interpretations of the 37 high energy neutrino events observed by the IceCube experiment in the South Pole. We examine the possibility to explain the observed n…
Gravitino Dark Matter in Split Supersymmetry with Bilinear R-Parity Violation
Giovanna Cottin, Marco A. Díaz, María José Guzmán +1
In Split-SUSY with BRpV we show that the Gravitino DM solution is consistent with experimental evidence on its relic density and life time. We arrive at this conclusion by performi…
