On strange quark scalar condensate in the nucleon

  • 1. Leningrad Inst. of Nuclear Physics, Gatchina (USSR)

Description

A well known difficulty with a large value of the σ term in πN scattering is analysed from positions of the QCD sum rules approach. The matrix element is related to flavour singlet correlation function of two quark condensates at zero momentum. The splittings and are calculated and turn to be in agreement with SU3 relations.
