Abstract

We evaluate the pion–nucleon and the pion–Delta sigma terms by employing the method of quantum chromodynamics (QCD) sum rules. The obtained value of the pion–nucleon sigma term is compatible with the larger values already anticipated by the recent calculations. It is also found that the pion–Delta sigma term is as large as the pion–nucleon sigma term.
