Universal 2-3 symmetry
Anjan S. Joshipura
Possible maximal mixing seen in the oscillations of the atmospheric neutrinos has led to postulate of a - symmetry which interchanges and . We argue that such symm…
Quark-Lepton universality and large leptonic mixing
Anjan S. Joshipura, A. Yu. Smirnov
A unified description of fermionic mixing is proposed which assumes that in certain basis () a single complex unitary matrix diagonalizes mass matrices of all fermions to th…
Theory of Neutrinos: A White Paper
R. N. Mohapatra, S. Antusch, K. S. Babu +29
During 2004, four divisions of the American Physical Society commissioned a study of neutrino physics to take stock of where the field is at the moment and where it is going in the…
Baryogenesis via Leptogenesis in presence of cosmic strings
Narendra Sahu, Pijushpani Bhattacharjee, Urjit A Yajnik
We study the effect on leptogenesis due to cosmic strings of a extension of the Standard Model. The disappearance of closed loops of cosmic strings can pro…
Gauge invariance of elementary particle processes taking place in presence of a background magnetic field
Kaushik Bhattacharya
Elementary particle scatterings and decays in presence of a background magnetic field are very common in physics, specially after the observation that the core of the neutron stars…
Dark matter and leptogenesis in gauged B-L symmetric models embedding MSM
Narendra Sahu, Urjit A Yajnik
We study the phenomenon of baryogenesis via leptogenesis in the gauged symmetric models by embedding the currently proposed model . It is shown that the lightest right…
