Type I seesaw mechanism for quasi degenerate neutrinos
Anjan S. Joshipura, Ketan M. Patel, Sudhir K. Vempati
We discuss symmetries and scenarios leading to quasi-degenerate neutrinos in type-I seesaw models. The existence of degeneracy in the present approach is not linked to any specific…
Neutrino Condensate as Origin of Dark Energy
Jitesh R. Bhatt, Bipin R. Desai, Ernest Ma +2
We propose a new solution to the origin of dark energy. We suggest that it was created dynamically from the condensate of a singlet neutrino at a late epoch of the early Universe t…
Testable Leptogenesis in extended Standard Model
Sudhanwa Patra
We have proposed a new minimal extension of the Standard Model with a heavy Majorana fermion triplet() and an extra scalar doublet() so that the seesaw mechanism is radiative…
Top polarization as a probe of new physics
Rohini M Godbole, Saurabh D Rindani, Kumar Rao +1
We investigate the effects of new physics scenarios containing a high mass vector resonance on top pair production at the LHC, using the polarization of the produced top. In partic…
Collective Flavor Oscillations Of Supernova Neutrinos and r-Process Nucleosynthesis
Sovan Chakraborty, Sandhya Choubey, Srubabati Goswami +1
Neutrino-neutrino interactions inside core-collapse supernovae may give rise to collective flavor oscillations resulting in swap between flavors. These oscillations depend on the i…
Strong gauge boson scattering at the LHC
Saurabh D. Rindani
In the standard model with electroweak symmetry breaking through the Higgs mechanism, electroweak gauge-boson scattering amplitudes are large if the Higgs boson is heavy, and elect…
