Abstract

A crossingsymmetric pionnucleon scattering amplitude with Regge behaviour and secondsheet resonance poles is constructed using suitable combinations of a representation proposed by CohenTannoudji Henyey Kane and Zakrzewski CHKZ The Regge residues for highenergy scattering are obtained in terms of the functionft which is used in construction of the CHKZ representation An attempt is made to find the form offt which gives the best fit to the highenergy chargeexchange differential crosssection in the forward direction It is also shown that the nucleon pole term imposes restrictions on the location of the branch point offt and that the fit at large t can be improved by modifying the π trajectory function so that it satisfies the bound αρ t Ct1/2 log t1 fort→∞Si costruisce un’ampiezza di scattering pionenucleone a simmetria incrociata con comportamento di Regge e poli di risonanza sul secondo foglietto facendo uso di opportune combinazioni di una rappresentazione proposta da CohenTannoudji Henyey Kane e Zakrzewski CHKZ Si ottengono i residui di Regge per lo scattering di alta energia in termini della funzioneft usata nella costruzione della rappresentazione di CHKZ Si tenta di trovare la forma dift che dà la migliore approssimazione alla sezione d’urto differenziale di scambio di carica di alta energia in avanti Si mostra anche che il termine di polo del nucleone impone restrizioni alla posizione del punto di diramazione dift e che l’approssimazione per t grande può essere migliorata modificando la funzione della traiettoria β in modo che essa soddisfi al vincolo αρ t Ct1/2 log t1 pert →∞Используя соответствуюшие комбинации представления предложенного КохеномТаннодьи Хением Кейном и Закржевским конструируется кроссингсимметричная амлитуда рассеяния пиона нуклоном имеюшая Реджеповедение и резонансные полюса на втором листе Вычеты Редже для рассеяния при высоких энергиях выражаются через функциюft которая используется при конструировании представления КохенаТаннодьи Хения Кеина и Закржевского Предпринимается попытка получить формуft которая дает наилучшую подгонку для дифференциального поперечного сечения перезарядки при высоких энергиях в направлении впере Также показывается что член нуклонного полюса наклдывает ограничения на распокожение точки ветвленияft и что соответствие при больших t может быть улучшено за счет модификации функции б траектории так чтобы удовлетворить условию αρ t Ct1/2 log t1 ириt→−∞
