Vector-meson production in electron-electron collisions

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The cross-section for production of a vector meson in an electron colliding beam experiment is calculated in lowest-order perturbation theory. The vector meson is coupled directly to lepton pairs with coupling constantg. An approximate scheme of calculation is found in which one of the electrons is scattered at a small angle with respect to the beam direction. With reasonable experimental accuracy, a 5% determination ofg is possible.

Riassunto

Si oalcola nel più basso ordine della teoria delle perturbazioni, la sezione efficace per la produzione di un mesone vettoriale in un esperimenlo con un fascio di elettroni in collisione. Il mesone vettoriale è edirettamente accoppiato a coppie di leptoni con una costante di accoppiamentog. Si trova uno schema di calcolo approssimato in cui uno degli elettroni subisce uno scattering con piccolo angolo rispetto alla direzione del fascio. Con una ragionevole precisione sperimentale è epossibile la determinazione dig al 5%.
