Strong and electromagnetic decays of the radially excited D-s and B-s mesons in light cone QCD sum rules

Recently, LHCb Collaboration announced the discovery of radial excitations of D-s and B-s mesons. In present work, we calculate the most promising strong and electromagnetic decay widths of radially excited D-s (2S) and B-s (2S) mesons within the light cone QCD sum rules method.
