نویسنده
چکیده
We recalculate the free energy of droplets of quark-gluon plasma in a bulk hadronic medium, and of hadronic bubbles in a bulk quark-gluon plasma, under conditions resembling the cosmological quark-hadron transition. The results are derived using MIT bag boundary conditions, numerically summing over quark and gluon energy levels, as well as in terms of surface tension plus curvature expansions of the density of state. Contrary to earlier investigations, we do not find a significant instability of the plasma against nucleation of hadron gas bubbles above the critical temperature. Finite size corrections to the free energy of a hadron bubble do not relate in a simple manner to the corrections for a plasma droplet. 12.38.Mh, 12.39.Ba, 98.80.Cq Typeset using REVTEX 1

First order quark hadron phase transition is considered in scaling hydrodynamics including the Csernai-Kapusta model of nucleation of hadronic bubbles leading to supercooling. The effect of viscosity on the entropy production is studied in ideal as well as in viscous hydrodynamics with and without supercooling. It is found that the excess entropy produced due to supercooling depends weakly on v...

We suggest a method of constructing gauge invariant quark and gluon distributions that describe an abstract QCD observable and apply this method to analyze angular momentum of a hadron. In addition to the known quark and gluon polarized structure functions, we obtain gauge invariant distributions for quark and gluon orbital angular momenta, and consider some basic properties of these distributi...

The effect of strong magnetic field on the stability and gross properties of bulk as well as quasi-bulk quark matter has been investigated using the conventional MIT bag model. Both the Landau diamagnetism and the paramagnetism of quark matter has been studied. How the quark hadron phase transition is affected by the presence of strong magnetic field has also been investigated. The equation of ...

Explicit quark-hadron duality in the limit of heavy quark mass is studied using the ’t Hooft model, where both partonic and hadronic amplitudes may be computed exactly. Results for weak decays of heavy mesons are presented for both standard spectator decays, where the duality limit is convincingly approached, and annihilation decays of the valence quark-antiquark pair, where the approach to asy...
