Observation of μ *+ (1385) rho0 (770) narrow bound state with the mass of 2.26 GeV in K-p interactions at 32 GeV/c
Description
The μ*+(1385) rho0(770) narrow bound state with the mass of 2.26+-0.02 GeV has been observed at 32 GeV/c in K-p-interactions. The product cross section multiplied by the branching ratio of the studied mode is found to be σB=8.4+-2.6 μb. It has been shown that the maximum production rate for this state is achieved at the Feynman variable x=0.4+-0.1. Different interpretations for the observed signal including a possibility of its identification with charmed νsub(c)sup(+) baryon are also discussed
