R-parity violating two-loop level rainbowlike contribution to the fermion electric dipole moment
Nodoka Yamanaka
We analyze the two-loop level -parity violating supersymmetric contribution to the electric and chromoelectric dipole moments of fermions with a lepton and a gaugino in the inte…
Chiral symmetry breaking patterns in the U_L(n)xU_R(n) meson model
G. Fejos
Chiral symmetry breaking patterns are investigated in the U_L(n)xU_R(n) meson model. It is shown that new classes of minima of the effective potential belonging to the center of th…
Time-dependent heavy-quark potential at finite temperature from gauge-gravity duality
Tomoya Hayata, Kanabu Nawa, Tetsuo Hatsuda
The potential between a heavy quark and an anti-quark inside the quark-gluon plasma (QGP) is studied on the basis of the gauge/gravity duality. A real-time complex potential V_{Q\b…
Relativistic hydrodynamics from projection operator method
Yuki Minami, Yoshimasa Hidaka
We study relativistic hydrodynamics in the linear regime, based on Mori's projection operator method. In relativistic hydrodynamics, it is considered that ambiguity about the fluid…
Magnetic Catalysis vs Magnetic Inhibition
Kenji Fukushima, Yoshimasa Hidaka
We discuss the fate of chiral symmetry in an extremely strong magnetic field B. We investigate not only quark fluctuations but also neutral meson effects. The former would enhance…
Charged vector mesons in a strong magnetic field
Yoshimasa Hidaka, Arata Yamamoto
We show that charged vector mesons cannot be condensed by a magnetic field. Although some hadron models predict the charged vector meson condensation in a strong magnetic field, we…
