| 英文摘要 | The process of pion axioproduction, aN -> pi N, with an intermediate Delta resonance is analyzed using baryon chiral parturbation theory. The Delta resonance is included in two ways: First, deriving the a Delta N-vertices, the axion is brought into contact with the resonance, and, second, taking the results of pi N elastic scattering including the Delta, it is implicitly included in the form of a pion rescattering diagram. As a result, the partial wave cross section of axion-nucleon scattering shows an enhancement in the energy region around the Delta resonance. Because of the isospin breaking, the enhancement is not as pronounced as previously anticipated. However, since the isospin breaking here is much milder than that for usual hadronic processes, novel axion-search experiments might still exploit this effect. |
