Contribution

It provides a comprehensive analysis of open charm mesons' spectra and decay characteristics, including molecular state identification, within a phenomenological framework.

Findings

Identification of experimental open charm states with orbital excitations.

Prediction of molecular-like states among charm mesons.

Analysis of decay constants and widths of D, D_s, and B_c mesons.

Abstract

We present here recent results on the investigations of the mass spectrum (S-states and P-states), decay constants, decay widths and life time of the D, $D_s$,and $B_c$mesons within the framework of phenomenological potential models.We also present the binding energy and the masses of the di-meson molecular systems with one or more charm meson combinations. Many of the newly found experimental open charm states are identified with the orbital excitations of the conventional open charm mesons while others like X(3872), Y(3930), $D_{sJ}$(2632, 2700) \emph{etc.}, are identified as molecular like states.
