- 論文の詳細を見る
We investigate the spectral properties of massless and massive quarks coupled with scalar and pseudo-scalar bosons at finite temperature in Yukawa models at the one-loop order. We show that the quak spectral function has a three-peak structure even for a finite but small quark mass. The behavior of the spectral function and the pole structure of the propagator are analyzed as functions of temperature and masses of the quark and bosons. Effects of the anomalous quark spectrum on the dilepton pruduction rate are briefly mentioned.
