Investigation of Lambda p invariant mass spectrum in K^--d --->Lambda p pi reaction

Abstract

In the present work, the in-flight kaon interaction on the deuteron target at incident momentum of is investigated in the channel by a phenomenological potential model. By considering the effect of resonance in the invariant mass spectra comes fromreaction, and a comparison between theoretical spectra and Braun’s data, we found the best theoretical spectrum fitted to the experimental data. The energy and width of resonance state are respectively extracted and from the fitting process.
