Charmed hadron photoproduction at COMPASS | | Xiao-Yun Wang

31 Dec 2015 | | Abstract: | Photoproduction of the charmonium-like state $Z_{c}(4200)$ and the charmed
baryon $Lambda_{c}^{ast }(2940)$ is investigated with an effective Lagrangian
approach and the Regge trajectories applying to the COMPASS experiment.
Combining the experimental data from COMPASS and our theoretical model we
estimate the upper limit of $Gamma_{Z_{c}(4200)
ightarrow J/psi pi }$ to be
of about 37 MeV. Moreover, the possibility to produce $Lambda_{c}^{ast
}(2940)$ at COMPASS is discussed. It seems one can try to search for this
hadron in the missing mass spectrum since the $t$-channel is dominating for the
$Lambda_{c}^{ast }(2940)$ photoproduction. | | Source: | arXiv, 1512.9203 | | Services: | Forum | Review | PDF | Favorites | |
