K^-pp态的首次独家测量--在2.85 GeV的pp到K^+ Lambda p反应中填充

First exclusive measurements of the K^-pp state - populated in the pp to K^+ Lambda p reaction at 2.85 GeV

T. Yamazaki

摘要:

我们分析了在T_p = 2.85 $ GeV to search for a K^-pp (= X) nuclear bound state to be formed in the pp to K^+ + X reaction. The deviation spectra of the K^+ missing-mass MM (K^+) and Lambda p invariant-mass M(Lambda-p) with selection of large-angle proton emission revealed a structure with M_X = 2265 +- 2 MeV/c2 and Gamma_X = 118 +- 8$ MeV时,从pp到K^+ λ p的排它过程的DISTO实验数据。

英文摘要:

We have analyzed data of the DISTO experiment on the exclusive pp to K^+ Lambda p process at T_p = 2.85$ GeV to search for a K^-pp (= X) nuclear bound state to be formed in the pp to K^+ + X reaction. The deviation spectra of the K^+ missing-mass MM (K^+) and Lambda p invariant-mass M(Lambda-p) with selection of large-angle proton emission revealed a structure with M_X = 2265 +- 2 MeV/c2 and Gamma_X = 118 +- 8$ MeV.
