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 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…
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…
Pion Dissociation In Hot Quark Medium
Abhijit Bhattacharyya, Sanjay K. Ghosh, Sibaji Raha
Pion dissociation in a medium of hot quark matter is studied. The decay width of pion is found to be large but finite at temperatures much higher than the so called critical temper…
Can Dilepton Suppression be seen in Heavy Ion Experiments ?
Abhijit Bhattacharyya, Jan-e Alam, Sibaji Raha +1
Effects of finite temperature correction to the dilepton emission rate in ultrarelativistic heavy ion collisions have been looked into. It has been seen that although the -peak…
