Investigation of the reaction pp->p K0 pi+ Lambda in search of the pentaquark
Investigation of the reaction pp->p K0 pi+ Lambda in search of the pentaquark
The reaction pp -> pK(0)pi(+) Lambda has been studied with the ANKE spectrometer at COSY-Julich at a beam momentum of 3.65 GeV/c in order to search for a possible signal of the pentaquark Theta(+)( 1540), decaying into the pK(0) system. By detecting four charged particles in the final state (pi(+...

The reaction pp -> pK(0)pi(+) Lambda has been studied with the ANKE spectrometer at COSY-Julich at a beam momentum of 3.65 GeV/c in order to search for a possible signal of the pentaquark Theta(+)( 1540), decaying into the pK(0) system. By detecting four charged particles in the final state (pi(+), pi(-) and two protons), the K-0 and the Lambda have been reconstructed to tag strangeness production. It has been found that the pi(+)Lambda missing-mass spectrum displays no significant signal expected from the Theta(+)(1540) excitation. The total cross section for the reaction pp -> pK(0)pi(+) Lambda has been deduced, as well as an upper limit for the Theta(+) production cross section. The intermediate Delta K-++(0) Lambda state seems to provide a significant contribution to the reaction. |
