The Cosmic QCD Phase Transition, Quasi-baryonic Dark Matter and Massive Compact Halo Objects
Shibaji Banerjee, Abhijit Bhattacharyya, Sanjay K. Ghosh +3
We propose that the cold dark matter (CDM) is composed entirely of quark matter, arising from a cosmic quark-hadron transition. We denote this phase as "quasibaryonic", distinct fr…
The low-energy nuclear density of states and the saddle point approximation
Sanjay K. Ghosh, Byron K. Jennings
The nuclear density of states plays an important role in nuclear reactions. At high energies, above a few MeV, the nuclear density of states is well described by a formula that dep…
The Cosmological Quark-Hadron Transition and Massive Compact Halo Objects
Shibaji Banerjee, Abhijit Bhattacharyya, Sanjay K. Ghosh +2
One of the abiding mysteries in the so-called standard cosmological model is the nature of the dark matter. It is universally accepted that there is an abundance of matter in the u…
Effect of In-Medium Meson Masses on Nuclear Matter Properties
Abhijit Bhattacharya, Sanjay K. Ghosh, S. C. Phatak
Masses of hadrons (baryons as well as mesons) are modified in the nuclear medium because of their interactions. In this paper we investigate the effect of in-medium meson masses on…
Stochastic Pionisation in Hot Quark-Gluon Matter
Jan -e Alam, Abhijit Bhattacharyya, Sanjay K. Ghosh +2
We present a microscopic approach to dynamical pionisation of the hot quark-gluon matter formed in ultrarelativistic heavy ion collisions. The time evolution of the system is descr…
Evolution of Structure Functions with Jacobi Polynomial: Convergence and Reliability
Sanjay K. Ghosh, Sibaji Raha
The Jacobi polynomial has been advocated by many authors as a useful tool to evolve non-singlet structure functions to higher . In this work, it is found that the convergence…
