Meson mass at real and imaginary chemical potentials
Kouji Kashiwa, Masayuki Matsuzaki, Hiroaki Kouno +2
The chemical-potential dependence of pi and sigma meson masses is analyzed at both real and imaginary chemical potentials, and , by using the Polyakov-…
Description of Four-Body Breakup Reaction with the Method of Continuum-Discretized Coupled-Channels
Tomoaki Egami, Takuma Matsumoto, Kazuyuki Ogata +1
We present a method for smoothing discrete breakup -matrix elements calculated by the method of continuum-discretized coupled-channels (CDCC). This smoothing method makes it pos…
Roberge-Weiss phase transitions and extended Z3 symmetry
H. Kouno, Y. Sakai, K. Kashiwa +2
Using the Polyakov extended Nambu-Jona-Lasinio (PNJL) model with imaginary chemical potential, the relation between the Roberge-Weiss (RW) phase transition and the extended Z3 symm…
A New Glauber Theory based on Multiple Scattering Theory
Masanobu Yahiro, Kosho Minomo, Kazuyuki Ogata +1
Glauber theory for nucleus-nucleus scattering at high incident energies is reformulated so as to become applicable also for the scattering at intermediate energies. We test validit…
Vector-type four-quark interaction and its impact on QCD phase structure
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +2
Effects of the vector-type four-quark interaction on QCD phase structure are investigated in the imaginary chemical potential region, by using the Polyakov-loop extended Nambu-Jona…
Correlations among discontinuities in QCD phase diagram
Kouji Kashiwa, Yuji Sakai, Hiroaki Kouno +2
We show, in general, that when a discontinuity of either zeroth-order or first-order takes place in an order parameter such as the chiral condensate, discontinuities of the same or…
