On Anisotropy of Ultra-High Energy Cosmic-Rays (2009)
We briefly summarize our study on anisotropy of Ultra-High Energy Cosmic-Rays (UHECRs), in which we define a statistics that measures the correlation between UHECRs and Large Scale Structure (LSS)....
We study the anisotropy signature which is expected if the sources of ultra high energy, >10^{19} eV, cosmic-rays (UHECRs) are extragalactic and trace the large scale distribution of luminous matter....
Flavoring Astrophysical Neutrinos: Flavor Ratios Depend on Energy (2005)
Electromagnetic (and adiabatic) energy losses of pions and muons modify the flavor ratio (measured at Earth) of neutrinos produced by pion decay in astrophysical sources,...
Phenomenological Consequences of Soft Leptogenesis (2004)
Soft supersymmetry breaking terms involving heavy singlet sneutrinos can be the dominant source of leptogenesis. The relevant range of parameters is different from standard leptogenesis: a lighter...
New Ways to Soft Leptogenesis (2004)
Grossman, Yuval, Kashti, Tamar, Nir, Yosef, Roulet, Esteban
Soft supersymmetry breaking terms involving heavy singlet sneutrinos provide new sources of lepton number violation and of CP violation. In addition to the CP violation in mixing, investigated...
Leptogenesis from Supersymmetry Breaking (2003)
Grossman, Yuval, Kashti, Tamar, Nir, Yosef, Roulet, Esteban
We show that soft supersymmetry breaking terms involving the heavy sneutrinos can lead to sneutrino-antisneutrino mixing and to new sources of CP violation, which are present even if a single...
