Production in High Energy Nuclear Collisions
We investigate the production of baryon in high energy nuclear
collisions via quark coalescence mechanism. The wave function of
is solved from the Schr\"odinger equation for the bound state of three charm
quarks by using the hyperspherical method. The production cross section of
per binary collision in a central Pb+Pb collision at
TeV reaches 9 nb, which is at least two orders of
magnitude larger than that in a p+p collision at the same energy. Therefore, it
is most probable to discover in heavy ion collisions at LHC, and
the observation will be a clear signature of the quark-gluon plasma formation.Comment: 6 pages, 5 figure
Nucleon Mass Splitting at Finite Isospin Chemical Potential
We investigate nucleon mass splitting at finite isospin chemical potential in
the frame of two flavor Nambu--Jona-Lasinio model. It is analytically proved
that, in the phase with explicit isospin symmetry breaking the proton mass
decreases and the neutron mass increases linearly in the isospin chemical
potential.Comment: 3 pages and no figure
