论文摘要

我们已经重新考虑了狭窄的底池状态$υ(1s)$ - $υ(3s)$在1982---1986在CESR,DORIS和VEPP-4校对中获得的结果,以解决质量确定程序的缺点。对于在CESR和DORIS进行的实验,这包​​括对1986年修订的电子质量值的辐射校正和使用的不正确的记录。在所有实验的分析中,共振产生和非谐振过程的干扰被忽略了。提出了五个实验的校正质量值。校正从0.1到0.4〜MEV不等。 CESR和\ Mbox {VEPP-4}之间的差异在$υ(1s)$质量上的结果已从3.3降低到1.8标准偏差。

We have reconsidered the results on the masses of the narrow bottomonium states $Υ(1S)$--$Υ(3S)$ obtained in 1982--1986 at CESR, DORIS and VEPP-4 colliders in order to fix shortcomings of the mass determination procedures. For experiments at CESR and DORIS this includes the incorrect accounting of the radiative corrections and usage of the electron mass value revised in 1986. In analyses of all experiments the interference of the resonance production and the nonresonant process was ignored. The corrected mass values for five experiments are suggested. The corrections vary from 0.1 to 0.4~MeV. The discrepancy between CESR and \mbox{VEPP-4} results on $Υ(1S)$ mass has been reduced from 3.3 to 1.8 standard deviations.
