Symmetry energy of dense matter in holographic QCD
Symmetry energy dense matter holographic QCD
2010/12/24
We study the nuclear symmetry energy of dense matter using holographic QCD. To this end, we consider two flavor branes with equal quark masses in a D4/D6/D6 model. We find that at high density the sym...
QCD under magnetic field: chiral magnetic effect at heavy ion collisions
chiral-magnetic e ect vector-current correlation charge separation
2011/1/10
In this talk, we report our recent studies for the chiral magnetic e ect, which signals the P- and CP-violations at heavy ion collisions. We compute the electric current and its correlations, induced ...

Walking technicolor theory attempts to realize electroweak symmetry breaking as the spontaneous
chiral symmetry breakdown caused by the gauge dynamics with slowly varying gauge coupling constant and ...
Lattice QCD at the physical point: light quark masses
Lattice QCD physical point light quark masses
2011/1/7
Ordinary matter is described by six fundamental parameters: three couplings (gravitational,
electromagnetic and strong) and three masses: the electron’s (me) and those of the up (mu)
and down (md) q...
OPE, Heavy-Quark Mass, and Heavy-Meson Decay Constants from QCD Sum Rules
OPE Heavy-Quark Mass Heavy-Meson Decay Constants from QCD Sum Rules
2011/1/7
We present a sum-rule extraction of the decay constants of heavy-lightmesons from the two-point
correlator of pseudoscalar currents [1]. To this end, we compare the perturbative expansions for the co...

Wave Functions of the Proton Ground State Uniform Background Magnetic Field
2011/1/13
We calculate the probability distributions of quarks in the ground state of the proton, and how
