Search for an I=1 resonance in the pp to K/sub 1//sup 0/K/sup +or-/ pi /sup +/ pi /sup -/ reaction, in the 1970 MeV mass region

Reports data from an experiment undertaken by the Glasgow-Liverpool- Lausanne/Neuchatel-Paris (IPN) collaboration in the 2-meters HBC at CERN. The beam was set up at 8 different incident momenta between 1.50 to 2.04 GeV/c. The kinematic reconstruction was performed by the THRESHGRIND programs. The n...

Sumario:Reports data from an experiment undertaken by the Glasgow-Liverpool- Lausanne/Neuchatel-Paris (IPN) collaboration in the 2-meters HBC at CERN. The beam was set up at 8 different incident momenta between 1.50 to 2.04 GeV/c. The kinematic reconstruction was performed by the THRESHGRIND programs. The number of events in this channel is the following: K/sub 1//sup 0/K/sup +or-/ pi /sup -or+/ pi /sup +/ pi /sup -/ 835 events. The four-body mass combination (K/sub 1//sup 0/K/sup +or-/ pi /sup +/ pi /sup -/) presents a significant bump (about 4 sigma 's) in the 1970 MeV mass region. A resonant effect at this mass was already observed in the rho pi pi combination, by another experiment. (0 refs).
