Structure of the inelastic overlap function for πp collisions in a diffraction dissociation model

Структура неупругой функции перекрытия для πp соударений в модели дифракционной диссоциации

Summary

Modified nova models of diffraction dissociation, including growing spin values of the fireballs and specific helicity structures of the amplitudes, are used to analyse the inelastic overlap functionF(s,t) for πp collisions ats=10, 30, 50 (GeV/c)2. The effect of the spins on the small-|t| slope ofF(s,t) is found to be large. With reasonable parameters and the assumption oft-channel helicity conservation these spin effects enable the model to reproduce the slope ofF(s, t) as calculated from the general optical theorem and the knowledge, of elastic scattering.

Riassunto

Per analizzare le funzioni di sovrapposizione elasticheF(s,t) per collisioni πp eds=10, 30, 50 (GeV/c)2 si adoperano modelli nova modificati delle dissociazioni diffrattive, comprendenti valori crescenti dello spin delle sfere di fuoco e specifiche strutture di elicità delle ampiezze. Si trova che l'effetto degli spin sulle pendenze diF(s,t) a piccoli |t| è grande. Con parametri ragionevoli e l'ipotesi della conservazione dell'elicità del canalet questi effetti di spin permettono che il modello riproduca la pendenza diF(s,t) quale è calcolata dal teorema ottico generale e dalla conoscenza dello scattering elastico.

Резюме

Для анализа неупругой функции перекрытияF(s, t) для πр соударений приs=10, 30, 50 (ГэВ/с)2 используутся модифицированные новые модели дифракционнои диссоциации, которые учитывают возрастающие значения спина файрболов и специфические стиральные структуры амплитуд. Получено, что влияние спинов на малый |t| наклонF(s, t) оказывается больщим. При разумных параметрах и предположении сохранения спиральности вt-канале эти спиновые эффекты позволяют прпспособить модель для воспроизведения наклонаF(s, t), который вычислен из общей оптической теоремы и знания упругого рассеяния.
