Electromagnetic divergences in weak processes

Электромагнитные расходимости в слабых процессах

  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

We generalize earlier calculations of the leading divergence in weak transitions between hadrons by including the electromagnetic interactions of the hadrons and of the charged W-boson. It is found that these can be removed by a self-mass counter term having the same form as that found earlier. However, there is an additional counter term in which the hadrons, in the form of the neutral Cabibbo current, are coupled directly to the electromagnetic field.

Riassunto

Si generalizzano i precedenti calcoli della divergenza principale nelle transizioni deboli fra adroni comprendendo le interazioni elettromagnetiche degli adroni e dei bosoni W carichi. Si trova che queste possono essere rimosse da un controtermine di automasse che ha la stessa forma di quello trovato prima. Tuttavia vi è un controtermine aggiuntivo in cui gli adroni, nella forma della corrente di Cabibbo neutra, sono accoppiati direttamente al campo elettromagnetico.

Резюме

Мы обобщаем предыдущие вычисления главной расходимости в слабых переходах между адронами, включая электромагнитные взаимодействия адронов и заряженного W бозона. Мы получаем, что эту расходимости могут быть устранены с помощью противочлена собственной массы, который имеет ту же форму, которая была получена ранее. Однако, существует дополнительный противочлен, в котором адроны, в форме нейтрального тока Кабиббо, непосредственно связаны с электромагнигным полем.
