Neutrino Masses from Non-minimal Gravitational Interactions of Massive Neutral Fermions
Abhinav Gupta, Namit Mahajan, Amitabha Mukherjee
A new mechanism is proposed for generating neutrino masses radiatively through a non-minimal coupling to gravity of fermionic bilinears involving massive neutral fermions. Such cou…
Topological Defects in the Left-Right Symmetric Model and their Relevance to Cosmology
U. A. Yajnik, Hatem Widyan, Shobhit Mahajan +2
It is shown that the minimal left-right symmetric model admits cosmic string and domain wall solutions. The cosmic strings arise when the SU(2)_R is broken and can either be destab…
Topological defects and conditions for baryogenesis in the Left-Right symmetric model
U. A. Yajnik, Hatem Widyan, Shobhit Mahajan +2
It is shown that the minimal Left-Right symmetric model admits cosmic string, domain wall and conditionally, monopole solutions. The strings arise when the is broken and…
