摘要
In this paper, we propose to investigate the d(N Omega) dibaryon production in the K(-)p -> d(N Omega) (Xi) over bar (0) process by utilizing a kaon beam with a typical momentum of approximately 10 GeV, which may be available at COMPASS, OKA@U-70, and SPS@CERN. The cross sections for K-p -> d(N Omega)(Xi) over bar (0) are estimated, and in particular, the magnitude of the cross sections is evaluated to be several hundred nanobarns at P-K = 20GeV. Considering that the d(N Omega) dibaryon dominantly decays into Xi Lambda and, Xi Sigma, we also estimate the cross sections for K(-)p -> Xi(0) Lambda(Xi) over bar (0) and K(-)p -> Xi-Sigma+ (Xi) over bar (0) d(N Omega) where the dibaryon can be observed in the invariant mass distributions of Xi(0) Lambda and Xi(-)Sigma(+), respectively.
