Behavior of Charmonium Systems after Deconfinement
Saumen Datta, Frithjof Karsch, Peter Petreczky +1
We present a study of charmonia in hot gluonic plasma, for temperatures upto three times the deconfinement transition temperature Tc. q \bar{q} systems with quark masses close to t…
Negative-Parity Baryons in Quenched Anisotropic Lattice QCD
Y. Nemoto, N. Nakajima, H. Matsufuru +1
We study negative-parity baryon spectra in quenched anisotropic lattice QCD. The negative-parity baryons are measured as the parity partner of the ground-state baryons. In addition…
Spontaneous violation of CP symmetry in the strong interactions
Michael Creutz
Some time ago Dashen pointed out that spontaneous CP violation can occur in the strong interactions. I show how a simple effective Lagrangian exposes the remarkably large domain of…
