Light front approach to correlations in hot quark matter

We investigate two-quark correlations in hot and dense quark matter. To this end we use the light front field theory extended to finite temperature T and chemical potential μ. Therefore it is necessary to develop quantum statistics formulated on the light front plane. As a test case for light front quantization at finite T and μ we consider the NJL model. The solution of the in-medium gap equation leads to a constituent quark mass which depends on T and μ. Two-quark systems are considered in the pionic and diquark channel. We compute the masses of the two-body system using a T-matrix approach. © 2006 Akadémiai Kiadó, Budapest.
