Reviving quark nuggets as a candidate for dark matter
Abhishek Atreya, Anjishnu Sarkar, Ajit M. Srivastava
We discuss a novel mechanism for segregation of baryons and anti-baryons in the quark-gluon plasma phase which can lead to formation of quark and antiquark nuggets in the early uni…
Spontaneous CP violation in quark scattering from QCD Z(3) interfaces
Abhishek Atreya, Anjishnu Sarkar, Ajit M. Srivastava
In this paper, we explore the possibility of spontaneous CP violation in the scattering of quarks and anti-quarks from QCD Z(3) domain walls. The CP violation here arises from the…
Spontaneous Left-Right Symmetry Breaking in Supersymmetric Models with only Higgs Doublets
Sudhanwa Patra, Anjishnu Sarkar, Utpal Sarkar
We studied the question of parity breaking in a supersymmetric left-right model, in which the left-right symmetry is broken with Higgs doublets (carrying ). Unlike the l…
Spontaneous Parity Violation in a Supersymmetric Left-Right Symmetric Model
Sudhanwa Patra, Anjishnu Sarkar, Utpal Sarkar +1
We propose a novel implementation of spontaneous parity breaking in supersymmetric left-right symmetric model, avoiding some of the problems encountered in previous studies. This i…
Gauge mediated supersymmetry breaking and the cosmology of Left-Right symmetric model
Sasmita Mishra, Anjishnu Sarkar, Urjit A. Yajnik
Left-Right symmetry including supersymmetry presents an important class of gauge models which may possess natural solutions to many issues of phenomenology. Cosmology of such model…
PeV scale Left-Right symmetry and baryon asymmetry of the Universe
Anjishnu Sarkar, Abhishek, Urjit A. Yajnik
We study the cosmology of two versions of supersymmetric Left-Right symmetric model. The scale of the symmetry breaking in these models is naturally low, GeV. S…
Cosmology in a supersymmetric model with gauged
Urjit A. Yajnik, Anjishnu Sarkar
We consider salient cosmological features of a supersymmetric model which is Left-Right symmetric and therefore possessing gauged symmetry. The requirement of breaking parity…
Naturalness of parity breaking in a supersymmetric SO(10) model
Anjishnu Sarkar, Urjit Yajnik
We consider a supersymmetric SO(10) model which remains renormalisable upto Planck scale. The cosmology of such a model passes through a Left-Right symmetric phase. Potential probl…
