Observation of. lambda. p mass enhancement in the reaction K/sup -/d. -->. lambda. p. pi. /sup +/. pi. /sup -/. pi. /sup -/

Journal Article · · Phys. Rev., D; (United States)
A study of ..lambda..p mass distribution is made from the analysis of bubble-chamber data of the reaction K/sup -/d ..-->.. ..lambda..p..pi../sup +/..pi../sup -/..pi../sup -/ at K/sup -/ beam momenta of 1.45 and 1.65 GeV/c. A statistically significant peak in the ..lambda..p mass distribution is observed at approx. =2130 MeV. Another ..lambda..p mass peak in the region approx. =2195--2210 MeV is also seen but its statistical significance depends on the choice of the background estimate.
