Superconvergence sum rules in ρπ scattering

Сверхсходящиеся правила сумм в рп рассеянии

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

Summary

We calculate the contributions of the A1 and A2 resonances to a set of six superconvergence sum rules in ρπ scattering. The π, ω and A1 terms go a good way towards saturation of the forward sum rules, and the A2 terms are rather small. The A2 contributions to the non-forward sum rules are larger, and two of them are still far from saturation.

Riassunto

Si calcolano i contributi delle risonanze A1 e A2 ad un gruppo di sei regole di somma di superconvergenza nello scattering ρπ. I termini del π, ω e A1 si avvicìnano molto alla saturazione delle regole di somma in avanti e i termini di A2 sono piuttosto piccoli. I contributi di A2 alle regole di somma non in avanti sono maggiori, e due di essi sono ancora lontani dalla saturazione.

Резюме

Мы вычисляем вклады A1 и A2 резонансов в систему шести суперсходящихся правил сумм в рп рассеянии. Члены п, щ и A1 идут правильным образом к насыщению правил сумм для рассеяния вперед, а члены A2 довольно малы. Вклад от A2 в правила сумм для рассеяния не на нулевой угол является большим, причем два из еще далеки пт насыщения.

  7. There is some point in considering (11) and (12), rather than, say, (5) and (12), since the former pair of equations tells us something about the structure of ρ-mesons of helicity 0 and ±1 under chiralSU 3×SU 3.

  8. Strictly speaking, (11) and (12) are only true for zero pion mass, whereas (5) to (10) hold for physical pions.
