Abstract

We have measuredpt andpi spectra of the pions and protons produced in six and twoprong interactions in a bubblechamber experiment The BNL 80 in liquidhydrogen bubble chamber was exposed to a 70 GeV/c negativepion beam The data are analysed in terms of the Hagedorn model and the twotemperature model of Wayland and Bowen The temperature of the interaction volume obtained from fitting thept spectra of the pions is below 140 MeV and for the protons it is close to 180 MeV Thept spectra of the pions yields a good fit to an expression given in the twotemperature model We have divided our sixprong data into peripheral and nonperipheral events and the temperature values of the two samples show considerable difference for the protonpt distributions We have gathered data from the other experiments at different energies We find that the temperature increases with the rise in incidentparticle energy and it decreases as the multiplicity of the pions produced increases at a fixed incident energyМы измерили спектрыpt иpt для пионов и протонов рожденных в шести и двухлучевых веанмодействиях на эксперименте в пузырьковой камере Юидкостноводородная пузырьковая камера BNL 80 in экспонировалась в 70 ГэВ/с пучке отрицательных пионов Полученные данные анализируются в терминах модели Хагедорна и двухтемпературной модели Вейленда и Бовона Температура обьема взанмодействия полученная из подгонки спектраpt пиохов оказывается ниже 140 МэВ а для протонов близкак 180 МэВ Спектрpl пионов хорошо соответствует выражению определяемому двухтемпературной Мы раеделили наши шестилучевые данные на лериферические и непериферические события и значения температир для двух подворок обнаруживают значительное раеличие дяяpt рапределения протонов тонв Мы собрали данные из других зкспериментов при различных энергиях Мы получнли что температура увеличивается с увеличением знергии подающих частиц и температура падает когда число рожденных пионов увеяичивается при фиксированной энергии падающих частицSi sono misurati gli spettri dipi ept dei pioni e dei protoni prodotti nelle interazioni a sei e a due rami in un esperimento con la camera a bolle Si è esposta la camera a bolle ad idrogeno liquido del BNL da 80 in ad un fascio di pioni negativi di 70 GeV/c Si analizzano i dati in termini del modello di Hagedorn e del modello a due temperature di Wayland e Bowey La temperature del volume di interazione ottenuta dallapprossimazione dello spettroo dipt dei pioni è al disotto di 140 MeV e per i protoni si avvicina a 180 MeV Lo spettro dipi dei pioni fornisce una buona approssimazione ad unespressione data nel modello a due temperature Si sono divisi i dati a sei rami in eventi periferici e non periferici e i valori della temperatura dei due campioni mostrano differenze considerevoli per le distribuzioni dipt dei protoni Si sono riuniti i dati ottenuti in altri esperimenti ad altre energie Si trova che la temperatura aumenta con laumento dellenergia della particella incidente e diminuisee collaumento della moltiplicità dei pioni per energie incidenti fisse
