Leptogenesis by curvature coupling of heavy neutrinos
Gaetano Lambiase, Subhendra Mohanty
We introduce a CP violating coupling between the Ricci curvature and the heavy right handed neutrinos. This splits the Majorana masses of the left and the right handed heavy neutri…
Fermion Masses in SO(10) Models
Anjan S. Joshipura, Ketan M. Patel
We examine many SO(10) models for their viability or otherwise in explaining all the fermion masses and mixing angles. This study is carried out for both supersymmetric and non-sup…
Chiral symmety breaking in 3-flavor Nambu-Jona Lasinio model in magnetic background
Bhaswar Chatterjee, Hiranmaya Mishra, Amruta Mishra
Effect of magnetic field on chiral symmetry breaking in a 3-flavor Nambu Jona Lasinio (NJL) model at finite temperature and densities is considered here using an explicit structure…
Forward-backward asymmetry in top quark production from light colored scalars in SO(10) model
Ketan M. Patel, Pankaj Sharma
The forward-backward asymmetry in top pair production at Tevatron has been reconfirmed by the CDF collaboration with 5.3 fb^{-1} of accumulated data. These measurements also report…
Vacuum structure and chiral symmetry breaking in strong magnetic fields for hot and dense quark matter
Bhaswar Chatterjee, Hiranmaya Mishra, Amruta Mishra
We investigate chiral symmetry breaking in strong magnetic fields at finite temperature and densities in a 3 flavor Nambu Jona Lasinio (NJL) model including the Kobayashi Maskawa t…
