Collective neutrino oscillations in non-spherical geometry
Basudeb Dasgupta, Amol Dighe, Alessandro Mirizzi +1
The rich phenomenology of collective neutrino oscillations has been studied only in one-dimensional or spherically symmetric systems. Motivated by the non-spherical example of coal…
Probing extended Higgs sector through rare b --> s mu+ mu- transitions
Ashutosh Kumar Alok, Amol Dighe, S. Uma Sankar
We study the constraints on the contribution of new physics in the form of scalar/pseudoscalar operators to the average forward backward asymmetry <A_{FB}> of muons in B --> K mu+…
Identifying neutrino mass hierarchy at extremely small theta(13) through Earth matter effects in a supernova signal
Basudeb Dasgupta, Amol Dighe, Alessandro Mirizzi
Collective neutrino flavor transformations deep inside a supernova are sensitive to the neutrino mass hierarchy even at extremely small values of theta(13). Exploiting this effect,…
CPT violation in long baseline neutrino experiments: a three flavor analysis
Amol Dighe, Shamayita Ray
We explore possible signals of CPT violation in neutrinos in the complete three-flavor framework. Employing a systematic expansion in small parameters, we analytically estimate the…
Spectral split in prompt supernova neutrino burst: Analytic three-flavor treatment
B. Dasgupta, A. Dighe, A. Mirizzi +1
The prompt nu_e burst from a core-collapse supernova (SN) is subject to both matter-induced flavor conversions and strong neutrino-neutrino refractive effects. For the lowest-mass…
Neutrinos from a core collapse supernova
Amol Dighe
The neutrino burst from a galactic supernova can help determine the neutrino mass hierarchy and , and provide crucial information about supernova astrophysics. Here we revi…
