Abstract |
Motivated by recent BESIII measurements of the singly Cabibbo-suppressed processes Lambda c+->Lambda K+pi 0 and Lambda c+->Lambda KS0 pi+ , we investigate the process Lambda c+->Lambda K0 pi+ by taking into account the contribution from the low-lying excited baryon Sigma*(1/2-), dynamically generated via the S-wave pseudoscalar meson-octet baryon interaction, as well as from the intermediate resonances K*(892) and N (1535). Our model successfully reproduces the BESIII pi+K0 invariant mass distribution, and predicts a distinct cusp structure around 1.43 GeV in the pi+Lambda invariant mass distribution, which is associated with the predicted Sigma*(1/2-). Future high-precise measurements of this process at BESIII, Belle II, and the proposed Super Tau-Charm Facility experiments will be crucial for testing the existence of Sigma*(1/2-) and advancing our understanding of the light baryon spectrum. |
