弱CC单π介子产生中的轻子质量效应

Lepton mass effects in weak CC single pion production

Krzysztof M. Graczyk, Jan T. Sobczyk

摘要:

比较了在Rein-Sehgal模型中考虑非零轻子质量的不同方法。由于π极项的轴向电流的修改包括在内,它表明,它们导致大的反中微子截面的减少和$dσ/dQ^2$的形状的变化。

英文摘要:

Different approaches to take into account nonzero lepton mass in the Rein-Sehgal model are compared. Modification of the axial current due to pion pole term are included and it is shown that they lead to large reduction of antineutrino cross section and a change of the shape of $dσ/dQ^2$.
