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