Photoproduction of Pentaquark and Chiral Symmetry Restoration in Hot and Dense Medium
arXiv:hep-ph/0505204 · doi:10.1103/PhysRevD.73.014005
Abstract
The photoproduction rate of pentaquark is calculated in a hot and dense medium. At high temperature and density, due to the restoration of chiral symmetry, photoproduction energy threshold is increased. Above the thresold the production cross section is strongly enhanced.
