Dilepton signal of a type-II seesaw model at CERN LHC: Reveals a TeV scale symmetry
We explore the discovery potential of doubly charged Higgs bosons (ξ±±) at the CERN
Large Hadron Collider (LHC). For moderate values of the coupling constants in the original …

Spontaneously broken parity and consistent cosmology with transitory domain walls
S Mishra, UA Yajnik - Physical Review D—Particles, Fields, Gravitation, and …, 2010 - APS
Domain wall structure which may form in theories with spontaneously broken parity is
generically in conflict with standard cosmology. It has been argued that Planck scale …

New ultraviolet operators in supersymmetric SO (10) GUT and consistent cosmology
P Banerjee, UA Yajnik - Physical Review D, 2020 - APS
We consider the minimal supersymmetric grand unified model based on the group SO (10)
and study conditions leading to possible domain wall formation. It has been shown earlier …

[HTML][HTML] PeV scale Left–Right symmetry and baryon asymmetry of the Universe
A Sarkar, UA Yajnik - Nuclear physics B, 2008 - Elsevier
We study the cosmology of two versions of supersymmetric Left–Right symmetric model. The
scale of the B–L symmetry breaking in these models is naturally low, 104–106 GeV …
