Abstract

• In this research work, the inclusive missing-mass spectrum of D(+, K+)X reaction at J-PARC E-27 experiment have been studied. JPARC E27 experiment was conducted to search for the simplest kaonic nuclear bound state by using D(+, K+)X reaction at the beam momentum of 1.7 GeV/c. In the E-27 experiment, high energy pion is incident upon deuteron target and interacts with neutron in the target to produce K , K and p. Due to the strong attractive force between K and p, * = (1405) is formed as a doorway state to populate K pp. The missing mass spectrum obtained from E-27 experiment at J-PARC has covered energy regions of quasi free -p, -p, *-p, *-p production and pp K bound state. The missing mass spectrum of D(+, K+)X reaction covering all the above energy regions have been analyzed by using Greens function method.
