Bu yazarlardan sadece Bursa Uludağ Üniversitesi mensuplarının girişleri yapılmıştırUsing a sample of 1.06 × 108φ(3686) events collected with the BESIII detector at BEPCII, the decays ηc(2S) → pp¯ and hcpp¯ are searched for, where ηc(2S) and hc are reconstructed in the decay chains φ(3686) → γηc(2S), ηc(2S) → pp¯ and χ(3686) → π0hc, hc→ pp¯, respectively. No significant signals are observed. The upper limits of the product branching fractions are determined to be B(φ(3686) → γηc(2S)) × B(ηc(2S) → pp¯) < 1.4 × 10-6and B(φ(3686) → π0hc) × B(hc→ pp¯) < 1.3 × 10-7at the 90% C.L.. The branching fractions for χcJ→ pp¯ (J = 0, 1, 2) are also measured to be (24.5 ± 0.8 ± 1.3, 8.6 ± 0.5 ± 0.5, 8.4 ± 0.5 ± 0.5) × 10-5, which are the world's most precise measurements. © 2013 American Physical Society.eninfo:eu-repo/semantics/closedAccessAstronomy & astrophysicsPhysicsArticle0003286019000012-s2.0-849798462838811https://doi.org/10.1103/PhysRevD.88.112001Astronomy & astrophysicsPhysics, particles & fieldsBaryon; Hadron; Physics
