13 May 2002 | | Journal: | Phys.Lett. B567 (2003) 159-166 | | Subject: | hep-ex hep-ph | | Affiliation: | IHEP, Protvino, Russia), V.N. Bolotov, S.V. Laptev, A.R. Pastsjak, A.Yu. Polyarush, R.Kh. Sirodeev (INR, Moscow, Russia | | Abstract: | The Dalitz plot slope parameters g, h and k for the K- -> pi0 pi0 pi- 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 pi- 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. | | Source: | arXiv, hep-ex/0205027 | | Services: | Forum | Review | PDF | Favorites | |
