A solvable model for high-energy scattering

Рещаемая модель для рассеяния при высоких знергиях

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

Summary

A Hamiltonian model is introduced to describe high-energy scattering and production. An approximation of the eikonal type is used to deal with the kinematic term of the colliding particles, and, within this approximation, the scattering problem is solved exactly. Unitarity is satisfied both for the elastic and the inelastic amplitudes. A comparison of the prediction of the model with some experimental data for p-p scattering is presented.

Riassunto

Si costruisce un modello hamiltoniano per descrivere i fenomeni di diffusione e produzione ad alta energia. Si usa un’approssimazione di tipo iconale per trattare il termine cinetico delle particelle incidenti e, entro tale approssimazione, il problema è risolto completamente. L’unitarietà è soddisfatta tanto per l’ampiezza elastica che per quella inelastica. Si presenta un confronto delle previsioni del modello con alcuni dati sperimentali per l’urto protone-protone.

Реэюме

Вводится модель с гамильтонианом для описания процессов рождения и рассеяния при высоких знергиях. Испольэуется приближение типа зйконала для рассмотрения кинетического члена соударяюшихся частиц. В рамках зтого приближения проблема рассеяния рещается точно. Унитарность выполняется и для упругой и для неупругой амплитуд. Предлагается сравнение предскаэаний рассматриваемой модели с некоторыми зкспериментальными данными для р-р рассеяния.
