Model analysis on thermal UV-cutoff effects on the critical boundary in hot QCD
Jiunn-Wei Chen, Kenji Fukushima, Hiroaki Kohyama +2
We study the critical boundary on the quark-mass plane associated with the chiral phase transition in QCD at finite temperature. We point out that the critical boundaries obtained…
Space- and time-like electromagnetic pion form factors in light-cone pQCD
Jiunn-Wei Chen, Hiroaki Kohyama, Kazuaki Ohnishi +2
We present a combined analysis of the space- and time-like electromagnetic pion form factors in light-cone perturbative QCD with transverse momentum dependence and Sudakov suppress…
Shear Viscosity of a Gluon Plasma in Perturbative QCD
Jiunn-Wei Chen, Hui Dong, Kazuaki Ohnishi +1
We calculate the shear viscosity to entropy density ratio of a gluon plasma in kinetic theory including the gg->gg and gg<->ggg processes. Due to the suppressed contr…
U_A(1) Anomaly in Hot and Dense QCD and the Critical Surface
Jiunn-Wei Chen, Kenji Fukushima, Hiroaki Kohyama +2
We discuss the chiral phase transition in hot and dense QCD with three light flavors. Inspired by the well known fact that the U_A(1) anomaly could induce first order phase transit…
Sigma meson in QCD sum rules using a two quark current with derivatives
Su Houng Lee, Kenji Morita, Kazuaki Ohnishi
We study the meson in QCD sum rules using a two quark interpolating field with derivatives. In the constituent quark model, the meson is composed of a quark and an antiquar…
Studying Diquark Structure of Heavy Baryons in Relativistic Heavy Ion Collisions
S. Yasui, S. H. Lee, K. Ohnishi +2
We propose the enhancement of yield in heavy ion collisions at RHIC and LHC as a novel signal for the existence of diquarks in the strongly coupled quark-gluon plasma produce…
