چکیده
Chiral symmetry restoration in a dense medium is to some extent a consequence of the nuclear pion cloud. These pions induce a mixing of the axial and vector current contributions in the axial and vector cor-relators. We discuss their influence on hadron masses and investigate the signal produced by the remaining contribution associated with chi-ral symmetry restoration. Using the quark-meson coupling model we find that the latter is associated with the reduction of hadron masses.

The three-dimensional four-fermion model with a Z 2 chiral symmetry and N = 4 fermion species in the system is investigated numerically at non-zero temparature T and chemical potential µ. The phase diagram in the (T, µ) plane is mapped out quantitatively. A detailed finite size scaling analysis shows that the T = 0, µ = 0 chiral phase transition is first order, whereas the T = 0, µ = 0 transiti...

We study mesonic and baryonic correlation functions in the temporal directions in the vicinity of the critical temperature T ≃ T c using the instanton liquid model, in which chiral symmetry restoration is driven by the formation of instanton-antiinstanton molecules. Although we find the signals for all hadronic poles to be drastically reduced, some hadronic states seem to survive the phase tran...

Several topics in hadron physics at different scales of resolution are discussed. First, deep-inelastic scattering from nucleons and nuclei is viewed in a light-cone coordinate space picture. Then the smooth transition from parton to hadron degrees of freedom is demonstrated by analysing generalized Q-dependent polarizabilities of the nucleon. Turning to low energy QCD we summarize recent devel...

We demonstrate that chiral symmetry restoration in quenched finite temperature QCD depends crucially on the Z3 phase of the Polyakov loop P. This dependence is a general consequence of the coupling of the chiral order parameter to the Polyakov loop. We construct a model for chiral symmetry breaking and restoration which includes the effect of a nontrivial Polyakov loop by calculating the effect...

Chiral symmetry serves as a guiding principle in low-energy hadron dynamics. An effective lagrangian, which explicitly breaks chiral symmetry via a small mass term, allows for a systematic method of calculating higher order corrections to tree-level results. This is applied to radiative muon capture on hydrogen, and to proton-proton π 0 production near threshold. Both processes pose theoretical...
