Charmonium-nucleon interaction from lattice QCD with a relativistic heavy quark action
Charmonium-nucleon interaction lattice QCD relativistic heavy quark action
2011/1/13
Detailed information of the low-energy interaction between the charmonia (hc and J=y) and the
nucleon is indispensable for exploring the formation of charmonium bound to nuclei. In order
to investig...
Constraints for the QCD phase diagram from imaginary chemical potential
Constraints QCD phase diagram imaginary chemical potential
2011/1/13
We present unambiguous evidence from lattice simulations of Nf = 3 QCD for two tricritical
points in the (T,m) phase diagram at fixed imaginary m/T = ip /3 mod. 2p /3, one in the light
and one in th...
How the Quark Number fluctuates in QCD at small chemical potential
Quark Number fluctuates QCD small chemical potential
2011/1/14
We discuss the distribution of the quark number over the gauge fields for QCD at nonzero quark
chemical potential. As the quark number operator is non-hermitian, the distribution is over the
complex...
The phase boundary for the chiral transition in (2+1)-flavor QCD at small values of the chemical potential
phase boundary for the chiral transition (2+1)-flavor QCD small values
2011/1/14
We determine the chiral phase transition line in (2+1)-flavor QCD for small values of the light
quark chemical potential. We show that for small values of the chemical potential the curvature
of the...
