Exploration of charmed pentaquarks

Abstract

In this work, we explore the charmed pentaquarks, where the relativistic five-quark equations are obtained by the dispersion relation technique. By solving these equations with the method based on the extraction of the leading singularities of the amplitudes, we predict the mass spectrum of charmed pentaquarks with $J^P=1/2^{\pm }$ and $3/2^{\pm }$, which is valuable to further experimental study of charmed pentaquark.
