18 Jul 2022 | | Abstract: | Recently, the LHCb Collaboration reported a near-threshold enhancement,
$X(3960)$, in the $D_s^+D_s^-$ invariant mass distribution. We show that the
data can be well described by either a bound or a virtual state below the
$D_s^+D_s^-$ threshold. The mass given by the pole position is $(3928pm3)$
MeV. Using this mass and the existing information on the $X(3872)$ and
$Z_c(3900)$ resonances, a complete spectrum of the $S$-wave hadronic molecules
formed by a pair of ground state charmed and anticharmed mesons is established.
Thus, pole positions of the partners of the $X(3872)$, $Z_c(3900)$ and the
newly observed $D_s^+D_s^-$ state are predicted. Calculations have been carried
out at the leading order of nonrelativistic effective field theory and
considering both heavy quark spin and light flavor SU(3) symmetries, though
conservative errors from the breaking of these symmetries are provided. | | Source: | arXiv, 2207.08563 | | Services: | Forum | Review | PDF | Favorites | |
