Gauged symmetry and baryogenesis via leptogenesis at TeV scale
Narendra Sahu, Urjit A. Yajnik
It is shown that the requirement of preservation of baryon asymmetry does not rule out a scale for leptogenesis as low as 10 TeV. The conclusions are compatible with see-saw mechan…

Srubabati Goswami, Raghavan Rangarajan, K. Agashe +37
This is the report of neutrino and astroparticle physics working group at WHEPP-8. We present the discussions carried out during the workshop on selected topics in the above fields…
B-L Cosmic strings and Baryogenesis
Pijushpani Bhattacharjee, Narendra Sahu, U. A. Yajnik
Cosmic strings arising from breaking of the gauge symmetry that occurs in a wide variety of unified models can carry zero modes of heavy Majorana neutrinos. Decaying a…
Quantum mechanical stability of fermion-soliton systems
Narendra Sahu, Urjit A. Yajnik
Topological objects resulting from symmetry breakdown may be either stable or metastable depending on the pattern of symmetry breaking. However, if they acquire zero-energy modes o…
