摘要The recently observed new member of the charm-strange family D-s(2632), which has a surprisingly narrow width, is challenging our theory. D-s(2317) and D-s(2457), which were observed earlier, have similar behaviors and receive various theoretical explanations. Some authors use the heavy hadron chiral effective theory to evaluate heavy-light quark systems and obtain a reasonable evaluation on the masses of D-s(2317) and D-s(2457). An alternative picture is to interpret them as four-quark or molecular states. In this work, we are following the latter and propose a unitive description for all three new members, D-s(2632), D-s(2317), and D-s(2457), and, at least, so far our picture is consistent with the data.
