F+ decay in SLAC lattice QCD

F+ распад в SLAC квантовой хромодинамике на рещетке

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

Summary

We derive, in the SLAC lattice QCD theory, the relevant large-distance effective interactions for the processes\(c + \bar s \to u + \bar d + G\) and\(c + \bar s \to u + \bar d + q\bar q\), q=u, d, s, where G is a gluon. In this way, we find the F+ decay rate Γ(F+ → all) ⋍ 2.1Γ(D+ → all) form F=2.02 GeV.

Riassunto

Si deriva, nella teoria del reticolo SLAC QCD, le rilevanti interazioni efficaci ad ampia distanza per i processi\(c + \bar s \to u + \bar d + G\) e\(c + \bar s \to u + \bar d + q\bar q\), q=u, d, s, dove G è un gluone. In questo modo, si trova la velocità di decadimento di F+ Γ(F+ → all) ⋍ 2.1 · · Γ(D+ → all) per unm F=2.02 GeV.

Реэюме

В рамках теории SLAC квантовой хромодинамики на рещетке мы выводим соответствуюшие зффективные вэаимодействия на больщих расстояниях для процессов\(c + \bar s \to u + \bar d + G\) и\(c + \bar s \to u + \bar d + q\bar q\), q=u, d s, где G есть глюон. Мы находим, что интенсивность F+ распада составляет Γ(F+ → все)=2.1Γ(D+ → все) дляm F=2.02 ГзВ.
