  • Cosmic separation of phases, density inhomogeneities and primordial nucleosynthesis 
    Rana, N. C; Datta, B; Raha, S; Sinha, B (Elsevier, 1990-04)
    The authors investigate the role of the cosmic QCD phase transition on the relative abundances of light elements in primordial nucleosynthesis, with particular attention on the so-called 7Li over-production problem.
  • Cosmological QCD phase transition and dark matter 
    Bhattacharyya, A; Alam, J; Sarkar, S; Roy, P; Sinha, B; Raha, S; Bhattacharjee, P (Elsevier, 1999-12)
    The authors calculate the size distribution of quark nuggets, which could be formed due to first order QCD phase transition in the early universe. They find that there are a large number of stable quark nuggets which could ...
  • On the Neutrino Emissivity of Degenerate Strange Quark Matter 
    Datta, B; Raha, S; Sinha, B (World Scientific Publishing Company, 1988-10)
    We examine the neutrino emissivity of a system of degenerate three-component (u, d, s) strange quark matter using improved expressions for the quark chemical potentials in a self-consistent manner, and obtain tighter bounds ...
  • Photon and dimuon pairs in an expanding quark-gluon plasma 
    Datta, B; Raha, S; Sinha, B (Elsevier, 1988-12)
    Diphotons and dimuons escaping the interaction regions in ultra-relativistic heavy-ion collisions are studied in a thermodynamical framework. The relevance of such an analysis for quark-gluon plasma diagnostics is highlighted.
  • Relics of the cosmological QCD phase transition 
    Bhattacharyya, A; Alam, J. E; Sarkar, S; Roy, P; Sinha, B; Raha, S; Bhattacharjee, P (The American Physical Society, 2000-04)
    The abundance and size distribution of quark nuggets ~QN’s!, formed a few microseconds after the big bang due to a first-order QCD phase transition in the early universe, has been estimated. It appears that stable QN’s could ...
  • Survivability of cosmological quark nuggets in the chromoelectric flux-tube fission model of baryon evaporation 
    Bhattacharjee, P; Alam, J. E; Sinha, B; Raha, S (The American Physical Society, 1993-11-15)
    The question of the survivability of quark nuggets against the process of baryon evaporation from their surfaces is studied within the context of a dynamical model, namely, the chromoelectric flux-tube fission model of ...
