Selection rules for Regge cuts

Правила отбора для раэреэов Редже

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

We combine the expectation that diagrams which generate Regge cuts must contain third double-spectral functions with the requirements of exchange degeneracy to arrive at a selection rule for Regge cuts. This rule prohibits Regge-Regge cuts from contributing to KN scattering, and we speculate that this prohibition might explain the observation that the K+p total cross-section is such a remarkably constant function of energy, and that the cross-sections for KN and -K N charge-exchange scattering rapidly become equal as the energy increases.

Riassunto

Si combina l’attesa che i diagrammi che generano tagli di Regge debbano contenere terze funzioni spettrali doppie con l’esigenza della degenerazione dello scambio per giungere ad una regola di selezione per i tagli di Regge. Questa regola proibisce che tagli Regge-Regge contribuiscano allo scattering KN, e si specula che questa proibizione potrebbe spiegare l’osservazione che la sezione d’urto totale K+p è una così marcatamente costante funzione dell’energia, e che le sezioni d’urto per lo scattering con scambio di carica KN e -K N diventano rapidamente uguali al crescere dell’energia.

Реэюмy

Мы общединяем предположение, что диаграммы, которые обраэуют раэреэы Редже, должны содержать третьи двойные спектральные функции, с требованиями обменного вырождения для того, чтобы получить правило отбора для раэреэов Редже. Это правило эапрешает « Редже-Редже » раэреэы, исходя иэ вклада в KN рассеяние. Мы считаем, что зто эапрешение может общяснить тот факт, что полное поперечное сечение К+р рассеяния является постоянной функцией знергии, и что поперечные сечения KN и -K N рассеяния с переэарядкой быстро становятся равными, когда знергия увеличивается.

  11. An estimate byC. Michael (Nucl.

However, this estimate was based on the eikonal prescription, in its noncrossing-symmetric form yet, and hence might not be reliable.
