摘要
We consider the matrix elements of the left-handed flavor-conserving four-quark operators in the nucleon and pion states. Using chiral symmetry, we derive relationships among these matrix elements. We argue that the rule of hyperon and kaon non-leptonic weak decay implies possible large strange-quark content in the nucleon and pion.
