Abstract

The first observation of a new meson state decaying into B_{c}^{+} and a photon is presented using a dataset of pp collisions at a center-of-mass energy sqrt[s]=13 TeV collected by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb^{-1}. The B_{c}^{+} mesons are reconstructed from a three-muon final state from B_{c}^{+}→J/ψ(μ^{+}μ^{-})μ^{+}ν_{μ}X decays, along with photons reconstructed via conversions to electron-positron pairs in the detector material. The new state is observed with a significance that exceeds 8 standard deviations. The mass difference between the new meson state and the ground-state B_{c}^{+} meson is measured to be 64.5±1.4(stat) _{-1.4}^{+1.0}(syst) MeV. This corresponds to a mass for the observed state of 6339.0±1.4(stat) _{-1.4}^{+1.0}(syst)±0.3(m_{B_{c}^{+}}) MeV, where the last uncertainty is due to the precision of the best knowledge of the B_{c}^{+} meson mass. The low mass difference value matches the theory expectations for the lowest vector state of the b[over ¯]c system, the B_{c}^{*+} meson.

用ATLAS探测器观测一个B_{c}^{*+}介子。

利用大型强子对撞机ATLAS探测器收集的质心能量sqrt[s]=13 TeV的pp碰撞数据集，首次观测到一个新的介子态衰变为B_{c}^{+}和一个光子，对应的综合光度为140 fb^{-1}。B_{c}^{+}介子由B_{c}^{+}→J/ψ(μ^{+}μ^{-})μ^{+}ν_{μ}X衰变的三介子最终态重构而成，光子通过在探测器材料中转换成电子-正电子对重构而成。观察到的新状态的显著性超过8个标准差。新介子态与基态B_{c}^{+}介子的质量差为64.5±1.4(stat) _{-1.4}^{+1.0}(syst) MeV。这对应于观测状态的质量为6339.0±1.4(stat) _{-1.4}^{+1.0}（syst）±0.3(m_{B_{c}^{+}}) MeV，其中最后的不确定性是由于B_{c}^{+}介子质量的最佳知识的精度。低质量差值符合b[over¯]c系统的最低矢量态B_{c}^{*+}介子的理论期望值。
