Baryon masses and chiral symmetry breaking
Description
We study the 1/2+ baryon octet within the ITEP sum rule approach. With only the input of one mixing angle for the interpolating baryon operator, the quark vacuum condensates and the strange quark mass, the best values for the masses are obtained for sup(1/3) approx.= 0.93 sup(1/3) and msub(s) approx.= 115 MeV. We also give results for the 3/2+ decuplet. (orig.)
