Centrality dependence of chemical freeze-out parameters from net-proton and net-charge fluctuations using hadron resonance gas model
Rama Prasad Adak, Supriya Das, Sanjay K. Ghosh +2
We estimate chemical freeze-out parameters in HRG and EVHRG model by fitting the experimental information of net-proton and net-charge fluctuations measured in Au + Au collisions b…
Shear viscosity due to the Landau damping from quark-pion interaction
Sabyasachi Ghosh, Anirban Lahiri, Sarbani Majumder +2
We have calculated the shear viscosity coefficient of the strongly interacting matter in the relaxation time approximation, where a quasi particle description of quarks with it…
Heavy lepton pair production in nucleus-nucleus collisions at LHC energy - a case study
Jan-e Alam, Bedangadas Mohanty, Sanjay K Ghosh +2
We present a study of lepton pair production in Pb+Pb collisions at = 5.5 TeV. The larger mass ( 1.77 GeV) compared to and $μ…
Mesonic Excitations of QGP: Study with an Effective Model
Paramita Deb, Abhijit Bhattacharyya, Saumen Datta +1
We study the correlations between quark-antiquark pairs in different quantum number channels in a deconfined plasma by using an effective model of QCD. Using the three flavour PNJL…
A consistent quasiparticle picture of Quark-Gluon plasma and the velocity of sound
Sanjay K. Ghosh, Tamal K. Mukherjee, Sibaji Raha
A thermodynamically consistent density dependent quark mass model has been used to study the velocity of sound in a hot quark-gluon plasma. The results are compared with the recent…
Shadowing in photo-production : role of in-medium hadrons
Jan-e Alam, Sanjay K. Ghosh, Pradip Roy +1
We study the effects of in-medium hadronic properties on shadowing in photon-nucleus interactions in Glauber model as well as in the multiple scattering approach. A reasonable agre…

Sanjay K. Ghosh, Byron Jennings
Possible formation of nucleus bound state is studied in the framework of Walecka model. The bound states are found in different nuclei ranging from to . These…
-mass Modification in - a Signal of Restoration of Chiral Symmetry or Test for Nuclear Matter Models ?
Abhijit Bhattacharyya, Sanjay K. Ghosh, Sibaji Raha
Two recent experiments have demonstrated that the effective -mass in nuclear medium, as extracted from the reaction, is substantially reduced. This has been a…
Strangelets in Terrestrial Atmosphere
Shibaji Banerjee, Sanjay K. Ghosh, Sibaji Raha +1
A new dynamical model for the propagation of strangelets through the terrestrial atmosphere is proposed.
Pion and Kaon dissociation in hot quark medium
Abhijit Bhattacharyya, Sanjay K. Ghosh, Sibaji Raha
Pion and kaon dissociation in a medium of hot quark matter is studied in the Nambu Jona-Lasinio model. The decay width of pion and kaon are found to be large but finite at temperat…
Dihyperon in Chiral Colour Dielectric Model
