Confinement, Quark Matter Equation of State and Hybrid Stars
S. B. Khadkikar, A. Mishra, H. Mishra
We consider here quark matter equation of state in a relativistic harmonic confinement model at zero temperature. The same is considered to study phase transition of neutron matter…
Decay-lepton angular distribution in polarized and -violating dipole couplings of the top quark
P. Poulose, Saurabh D. Rindani
In the presence of an electric dipole coupling of to a photon, and an analogous ``weak" dipole coupling to the , violation in the process $e^+e^- \rightarrow t \…
Effect of magnetic field on the strange star
S. Chakrabarty, P. K. Sahu
We study the effect of a magnetic field on the strage quark matter and apply to strange star. We found that the strange star becomes more compact in presence of strong magnetic fie…
Quasi Goldstone Fermion As a Sterile Neutrino
E. J. Chun, A. S. Joshipura, A. Yu. Smirnov
The existence of sterile neutrino is hinted by simultaneous explanation of diverse neutrino anomalies. We suggest that the quasi Goldstone fermions (QGF) arising in supersymmetric…
Cerenkov radiation by neutrinos in a supernova core
Subhendra Mohanty, Manoj K. Samal
Neutrinos with a magnetic dipole moment propagating in a medium with a velocity larger than the phase velocity of light emit photons by the Cerenkov process. The Cerenkov radiation…
Test of the Equivalence Principle from Neutrino Oscillation Experiments
R. B. Mann, U. Sarkar
We consider the hypothesis that neutrino oscillation data can be explained if the gravitational couplings of (massless or degenerate mass) neutrinos are flavour non--diagonal, in v…
