Quasiparticle picture of quarks near chiral transition at finite temperature
نویسنده
چکیده
We investigate, using a chiral effective model, the quark spectrum in the critical region of the chiral transition focusing on the effect of the possible mesonic excitations in the quark-gluon plasma phase. We find that there appears a novel three-peak structure in the quark spectra. We elucidate the mechanism of the appearance of the multi-peak structure with the help of a Yukawa model with an elementary boson.

Quasiparticle picture of quarks near chiral phase transition
We study how the quasiparticle picture of the quark can be modified near but above the critical tempearture (Tc) of the chiral phase transition; we incorporate into the quark self-energy the effects of the precursory soft modes of the phase transition, i.e., ‘para-σ(π) meson’. It is found that the quark spectrum has a three-peak structure near Tc: We show that the additional new spectra origina...
متن کاملFinite temperature transitions in lattice QCD with Wilson quarks: Chiral transitions and the influence of the strange quark.
The nature of finite temperature transitions in lattice QCD with Wilson quarks is studied near the chiral limit for the cases of 2, 3, and 6 flavors of degenerate quarks (N F = 2, 3, and 6) and also for the case of massless up and down quarks and a light strange quark (N F = 2+1). Our simulations mainly performed on lattices with the temporal direction extension N t = 4 indicate that the finite...
متن کاملFermionic Collective Modes in QGP near Critical Temperatures
We investigate the quark spectrum in the quark-gluon plasma phase near color superconducting (CS) and chiral phase transitions. Owing to the precursory soft modes of the phase transitions, there appear novel excitaion spectra: In the CS transition, the quark matter shows non-Fermi liquid behavior and leads to the pseudogap in the density of states of quarks. In the chiral transition, three coll...
متن کاملSpectrum of Soft Mode with Thermal Mass of Quarks above Critical Temperature
We study effects of a thermal-quark mass and Landau damping of quarks on the chiral phase transition and its soft modes at finite temperature. For this purpose we employ a simple model with the quark propagator obtained in the hard thermal loop approximation. We show that the chiral phase transition is second order even if quark have a finite thermal mass, and the thermal mass suppresses the ch...
متن کاملQuark Spectrum near Chiral Transition Points
Near the critical temperature of the chiral phase transition, a collective excitation due to fluctuation of the chiral order parameter appears. We investigate how it affects the quark spectrum near but above the critical temperature. The calculated spectral function has many peaks. We show this behavior can be understood in terms of resonance scatterings of a quark off the collective mode.
