Two-Gluon Production and Longitudinal Correlations in the Color Glass Condensate
Kenji Fukushima, Yoshimasa Hidaka
We derive an analytical expression for the two-gluon production in the pA (light-heavy) collisions, and focus specifically on the rapidity dependent part. We approximate the gauge…
Baryons and the phase diagram for a large number of colors and flavors
Yoshimasa Hidaka, Larry D. McLerran, Robert D. Pisarski
We consider the possible phases of a non-Abelian gauge theory, as a function of temperature and quark chemical potential, when both the number of colors and flavors is very large.…
Suppression of the Shear Viscosity in a "semi" Quark Gluon Plasma
Yoshimasa Hidaka, Robert D. Pisarski
We consider QCD at temperatures T near Tc, where the theory deconfines. We distinguish between a "complete" Quark Gluon Plasma (QGP), where the vacuum expectation value of the reno…
Model study of the sign problem in a mean-field approximation
Yoshimasa Hidaka
We study the sign problem of the fermion determinant at nonzero baryon chemical potential. For this purpose we apply a simple model derived from Quantum Chromodynamics, in the limi…
Effect of pion thermal width on the sigma spectrum
Tetsuo Nishikawa, Yoshimasa Hidaka, Munehisa Ohtani +1
We study the effect of the thermal width of on the spectral function of . In order to take into account a finite thermal width of , we replace the internal pion mass in t…
