Abstract

The energy dependence of the energy and position resolutions of the electromagnetic calorimeter prototype made of lead tungstate crystals produced in Bogoroditsk (Russia) and Shanghai (China) is presented. These measurements were carried out at the Protvino accelerator using a 1–45 GeV electron beam. The crystals were coupled to photomultiplier tubes. The dependence of energy and position resolutions on different factors as well as the measured electromagnetic shower lateral profile are presented. [Copyright &y& Elsevier]

Abstract

The Dalitz plot slope parameters g, h and k for the K−→π0π0π− decay have been measured using in-flight decays detected with the ISTRA+ setup operating in the 25 GeV negative secondary beam of the U-70 PS. About 252 K events with four-momenta measured for the π− and four involved photons were used for the analysis. The values obtained g=0.627±0.004(stat)±0.010(syst), h=0.046±0.004(stat)±0.012(syst), k=0.001±0.001(stat)±0.002(syst) are consistent with the world averages dominated by K+ data, but have significantly smaller errors.
