Abstract

We display the hypothesis that multipleparticle production proceeds via two different processes called pionization and fragmentation We specify these two processes and then plot the inclusive singleparticle production spectraEdN/d3p in the cm variablesx = 2p l /sqrt s andy = tgh1 pl/E It is shownthat our curves are consistent with CERN ISR data where such exist By extrapolation to regions where so far no sufficient data are presented we predict a pionization double peak atx =y = 0 and a dip or shoulder in the transition region from pionization to fragmentation at some intermediate value of ¦x¦ and ¦y¦Мы исследуем гипотез у что множественное рождение частиц прои сходит через два различных п роцесса называемых п ионизацией и фрагментацией Мы конкретизируем эт и два процесса и затем вычерчиваем инклюзи вные одночастичные спектры рождения E dN/d3p в переменных системы ц ентра масс x=2pl/√s и y=tgh1 pl/E Показывается чт о наши кривые согласу ются с CERN ISR данными Предлагается экстра поляция в области где пока нет достаточных данных И спользуя эту экстраполяцию мы предсказываем двойн ой пик пионизации при x=у=0 и провал или выступ в пе реходной области от п ионизации к фрагментации при нек оторых промежуточных значе нияхx иуSi espone l’ipotesi che la produzione di particelle multiple proceda attraverso due processi diversi chiamati pionizzazione e frammentazione Si descrivono speciflcamente questi due processi e quindi si tracciano gli spettri della produzione inclusiva di particelle singoleEdN/d3p in funzione delle variabili del centro di massax = 2p l /sqrt s ey = tgh1 pl/E Si mette in luce ehe queste curve concordano con i dati CEEN ISR laddove questi esistono Estrapolando a regioni in cui ancora non sono stati presentati dati sufflcienti si prevede un picco doppio di pionizzazione perx = y = 0 e un avvallamento o spalla nella regione di transizione dalla pionizzazione alla frammentazione a un certo valore intermedio di ¦x¦ e ¦y¦
