Abstract

Abstract: The radiative decays χc1(3872) → ψ(2S) γ and χc1(3872) → J/ψγ are used to probe the nature of the χc1(3872) state using proton-proton collision data collected with the LHCb detector, corresponding to an integrated luminosity of 9 fb1. Using the B+ → χc1(3872)K+ decay, the χc1(3872) → ψ(2S) γ process is observed for the first time and the ratio of its partial width to that of the χc1(3872) → J/ψγ decay is measured to be

where the first uncertainty is statistical, the second systematic and the third is due to the uncertainties on the branching fractions of the ψ(2S) and J/ψ mesons. The measured ratio makes the interpretation of the χc1(3872) state as a pure D0 \( {\overline{\textrm{D}}}^{\ast 0} \) + \( {\overline{\textrm{D}}}^0 \) D*0 molecule questionable and strongly indicates a sizeable compact charmonium or tetraquark component within the χc1(3872) state.

利用辐射衰变探测χc1(3872)态的性质
摘要:利用LHCb探测器收集到的质子-质子对撞数据,用辐射衰变χc1(3872)→ψ(2S)γ和χc1(3872)→J/ψγ来探测χc1(3872)态的性质,对应的综合光度为9 fb-1。利用 B+ → χc1(3872)K+ 衰变,首次观测到 χc1(3872) → ψ(2S) γ 过程,并测量出其部分宽度与 χc1(3872) → J/ψγ 衰变部分宽度之比,其中第一个不确定性是统计不确定性、ψ(2S)和 J/ψ 介子分支分数的不确定性造成的。测得的比值使得把χc1(3872)态解释为一个纯D0\( {\overline\{textrm{D}}}^{\ast 0} \) + \( {\overline\{textrm{D}}}^0 \) D*0分子的观点受到质疑,并强烈表明在χc1(3872)态中存在一个相当大的紧凑粲子或四夸克成分。

期刊介绍: The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
