Abstract

We present a theoretical analysis of the process Λc+pKˉ0π0\Lambda_c^+ \to p\bar{K}^0 \pi^0 within the chiral unitary approach, with particular emphasis on the dynamically generated N(1535)N(1535) resonance. In addition to N(1535)N(1535), our model incorporates contributions from other intermediate resonances including N(1650)N(1650), K(892)K^*(892), K0(1430)K_0^*(1430), N(1440)N(1440), and Σ(1750)\Sigma(1750). The calculated invariant mass distributions and Dalitz plot are in good agreement with the recent Belle measurements. Our analysis highlights the crucial role of N(1535)N(1535) state in this decay channel and supports its interpretation as a dynamically generated state arising from coupled-channel meson-baryon interactions.
