Abstract

We report the observation of a heavy particle $J$, with mass $m=3.1$ GeV and width approximately zero. The observation was made from the reaction $p+\mathrm{Be}\ensuremath{\rightarrow}{e}^{+}+{e}^{\ensuremath{-}}+x$ by measuring the ${e}^{+}{e}^{\ensuremath{-}}$ mass spectrum with a precise pair spectrometer at the Brookhaven National Laboratory's 30-GeV alternating-gradient synchrotron.

重粒子的实验观察[J]

我们报道了重粒子J的观测，其质量m=3.1 GeV，宽度近似为零。在布鲁克海文国家实验室的30-GeV交流梯度同步加速器上，用精密对谱仪测量了${e}^{+}{e}^{\ensuremath{-}}$的质谱，从反应$p+\ mathm {Be}\ensuremath{\rightarrow}{e}^{+}}+{e}^{\ensuremath{-}} $得到了观测结果。
