A calorimeter with wavelength shifter read-out for particles at small angles in proton-antiproton collisions

Abstract We report the results of a test of two total absorption calorimeters with wavelength shifter read-out. They are now installed in the very forward parts of the UA1 experiment at the proton-antiproton collider at CERN. The response and resolution obtained with electrons and hadrons in the energy range 2–10 GeV are presented.

Inclusive study of hadron production by e+e− annihilation for 1.4⩽√s⩽2.3 GeV at adone

SummaryResults are reported on the inclusive study of the production of charged particles in the reaction e+e− → many hadrons in the c.m. energy range √s=(1.4 ÷ 2.3) GeV. The ratio between the kaons detected in the MEA apparatus at Adone and the corresponding total number of particles has been measured. The inclusive momentum distributions of the detected particles are given and the mean charged-particle energy and the mean observed multiplicity are evaluated.RiassuntoSi riportano i risultati di uno studio inclusivo sulla produzione di particelle cariche prodotte nella reazione e+e−→molti adroni nell’intervallo di energia del centro di massa √s=(1.4÷2.3) GeV. È stato misurato il rapporto tra il numero di K± rivelato dall’apparato MEA ed il corrispondente numero totale di particelle cariche. Si presentano le distribuzioni inclusive dei momenti delle particelle cariche rivelate per tre intervalli di √s ed inoltre — in funzione di √s — l’energia media e la molteplicità media delle particelle cariche rivelate.
