论文摘要
从第一原则中，具有相同夸克含量和相似质量的粒子应具有相似的运动学分布。可以使用横向质量缩放来估计此类颗粒动量分布的可能差异。基于此扩展，发现在LHC下测得的激发底池状态与$υ$（1）有显着不同，以至于$υ$（2s）的综合收益率是比质量差异所解释的$υ$（2s）的1.6倍和$υ$ 2.4倍的2.4倍。该程序解释了如何制定估计值，并将其与在LHC执行的其他测量结果相关联。
From first principles, particles with the same quark content and similar masses should have similar kinematic distributions. Transverse mass scaling may be employed to estimate possible differences in the momentum distribution of such particles. Based on this scaling the excited bottomonium states measured at the LHC are found to be significantly different from $Υ$(1S) to the extent that the integrated yield of $Υ$(2S) is 1.6 times less and $Υ$(3S) 2.4 times less than would be explained by the mass difference. This proceeding explains how the estimate is worked out and relates it to other measurements performed at the LHC.
