Chiral Baryon Fields in the QCD Sum Rule    [PDF]

Hua-Xing Chen

We study the local baryon fields in the QCD sum rule. We only consider the single baryon fields and calculate their operator product expansions. We find that the octet baryon fields belonging to the chiral representations [(3,3*)+(3*,3)] and [(8,1)+(1,8)] and the decuplet baryon fields belonging to the chiral representations [(3,6)+(6,3)] lead to the baryon masses which are consistent with the experimental data of ground baryon masses. We also check our normalizations for baryon fields in PRD81:054002(2010) and find that they are well-defined.
