Bu yazarlardan sadece Bursa Uludağ Üniversitesi mensuplarının girişleri yapılmıştır.By analyzing a data set of 2.92 fb(-1) of e(+) e(-) collision data taken at root s = 3.773 GeVand 106.41 x 10(6) psi(3686) decays taken at root s = 3.686 GeVwith the BESIII detector at the BEPCII collider, we measure the branching fraction and the partial decay width for psi(3770)->gamma chi c0 to be B(psi(3770)->gamma chi c0) = (6.88 +/- 0.28 +/- 0.67) x 10(-3) and Gamma[psi(3770)->gamma chi c0] = (187 +/- 8 +/- 19) keV, respectively. These are the most precise measurements to date.eninfo:eu-repo/semantics/openAccessAstronomy & astrophysicsPhysicsCross-sectionsMonte-carloMassArticle0003687836000152-s2.0-84949668592103109753Astronomy & astrophysicsPhysics, nuclearPhysics, particles & fieldsCharmonium; Drift Chambers; Branching
