We investigate S=2 production from the ΛpK+X reactions within the effective Lagrangian approach. The ΛpK+ΛΛ and ΛpK+Ξp reactions are considered to find the lightest S=2 system, which is H-dibaryon. We assume that the H(2250)ΛΛ, and H(2270)Ξp decays with the intrinsic decay width of 1 MeV. According to our calculations, the total cross sections for ΛpK+ΛΛ and ΛpK+Ξp reactions were found to be of the order of a few μb in the Λ beam momentum range of up to 5GeV/c. Furthermore, the direct access of information regarding the interference patterns between the H-dibaryon and nonresonant contributions was demonstrated.

Λp→K+X反应中的双奇异性产生

我们调查 =-2 从生产 Λ+X有效拉格朗日方法中的反应。这Λ+ΛΛΛ+Ξ- 反应被认为是找到最轻的 =-2 系统,即 H-二重子。我们假设H(2250)ΛΛ, 和 H(2270)Ξ-以 1 MeV 的固有衰减宽度衰减。根据我们的计算,总截面为Λ+ΛΛΛ+Ξ- 发现反应是几个数量级的 μ 在里面 Λ 光束动量范围可达 5电子伏特/C. 此外,直接访问有关干涉模式的信息H-二重子和非共振贡献被证明。
