Erratum: Isospin violation in QCD sum rules for baryons
PACS number(s): 11.55.Hx. , 11.30.Hv, 14.20.Dh, 99.10.+g In a recent paper [1], it was brought to our attention that some numerical factors in our equations were in error. In Eq. (3.12), the second sum rule for the nucleon, the term reading —za2 should read —za . As a consequence, the term sa2 in Eq. (3.34) is replaced by &a . There is also a change in the sum rule for the Z hyperons. In Eq. (3...
متن کاملIsospin violation in QCD sum rules for baryons.
We thoroughly analyze isospin-violating effects in QCD sum rules for the masses of nucleons, X, and :hyperons. After comparing with experimental mass splittings in isotopic multiplets, we obtain for the isospin breaking in the quark condensate (0~uu —dd ~0) /(0~uu ~0) =(2+1)X 10 ', a value significantly smaller than the one usually adopted. We present arguments in favor of our result and critic...
متن کاملFinite energy chiral sum rules in QCD
The saturation of QCD chiral sum rules of the Weinberg-type is analyzed using ALEPH and OPAL experimental data on the difference between vector and axial-vector correlators (V-A). The sum rules exhibit poor saturation up to current energies below the tau-lepton mass. A remarkable improvement is achieved by introducing integral kernels that vanish at the upper limit of integration. The method is...
متن کاملPredicative Ability of QCD Sum Rules for Decuplet Baryons
QCD sum rules for decuplet baryon two-point functions are investigated using a comprehensive Monte-Carlo based procedure. In this procedure, all uncertainties in the QCD input parameters are incorporated simultaneously, resulting in realistic estimates of the uncertainties in the extracted phenomenological parameters. Correlations between the QCD input parameters and the phenomenological parame...
متن کاملPredictive Ability of QCD Sum Rules for Excited Baryons
The masses of octet baryons are calculated by the method of QCD sum rules. Using generalized interpolating fields, three independent sets of QCD sum rules are derived which allow the extraction of low-lying N* states with spin-parity 1/2+, 1/2and 3/2in both the non-strange and strange channels. The predictive ability of the sum rules is examined by a Monte-Carlo based analysis procedure in whic...
