Quark-gluon transport theory II. Color response and color correlations in a quark-gluon plasma

Annals of Physics, 1986
Starting from a classical kinetic description of the quark-gluon plasma, we derive in the linear response approximation the color response function near thermodynamic equilibrium. From its poles the dispersion relations for the collective color modes (one longitudinal and one transverse) are obtained.

Nature of the photon correlation function for quark-gluon plasma

Physical Review C, 1994
The correlation function for intensity interferometry of high energy photons emitted from an expanding quark-gluon plasma is examined. It is reiterated that the correlation function for identical bosons emitted from two point sources is given by 1+cos([Delta][ital k][center dot][Delta][ital x]) and will oscillate between 0 and 2, depending on the ...

Long-range correlations and bulk viscosity in the quark-gluon plasma

Nuclear and Particle Physics Proceedings, 2016
Abstract We study long-distance features of the quark-gluon plasma, that are crucial for the dynamics of the system, with an infrared improved framework, the Gribov-Zwanziger quantization. Strikingly, at high temperature we uncover the presence of massless modes that violate the positivity of the quark spectral function.

Spectra and correlations in locally equilibrium hadron and quark-gluon systems

Nuclear Physics A, 1994
Abstract The single- and multi-particle inclusive boson spectra for locally equilibrium gas are studied using the method of statistical operator. The thermal Wick's theorem is generalized and the analytical solution of the problem in boost-invariant approach is found.

On Multiplicity Difference Correlators in Second-Order Quark-Gluon Plasma Phase Transition

Chinese Physics Letters, 1999
The multiplicity difference correlators between two well-separated bins are studied in second-order quark-gluon plasma (QGP) phase transition within the Ginzburg-Landau model. For the case with very low mean multiplicities, an exponent γ is found, which has very weak dependence on the parameters of the model and can be used as a signal for the ...

Evolution of singularities in unequal time correlator in thermalization of quark gluon plasma

Nuclear Physics A, 2013
Abstract We studied thermalization of strongly coupled gauge theory using a gravitational collapse model. In particular, we studied unequal time correlator for the glue ball operator. We found singularities of the correlator for zero momentum sector is consistent with a geometric optics picture in the gravitational theory.

Hanbury Brown/Twiss correlations for expanding hadron and quark-gluon matter

Nuclear Physics A, 1989
Abstract Some basic theoretical and experimental aspects of the interferometry method for expanding sources are discussed. We summarize the pion interferometry results for sources of a hydrodynamical type, analyze the features of the correlation method for a deflagrating mixed qg-h phase and the photon interferometry of an expanding quark-gluon ...

Quark-gluon correlation functions relevant to single transverse spin asymmetry

2018
This thesis presents the evaluation of the relative contributions of various twist-3 quark-gluon correlation functions relevant to single transverse spin asymmetry (SSAs) in a quark-diquark model of the nucleons. The twist-3 quark-gluon correlation functions responsible for gluonic pole and fermionic pole contributions are calculated and compared.
