Dynamically generated $N^{*}$ and $Lambda^*$ resonances in the hidden charm sector around 4.3 GeV


الملخص بالإنكليزية

The interactions of $bar{D}Sigma_{c}$-$bar DLambda_c$, $bar{D}^{*}Sigma_{c}$-$bar D^*Lambda_c$, and related strangeness channels, are studied within the framework of the coupled channel unitary approach with the local hidden gauge formalism. A series of meson-baryon dynamically generated relatively narrow $N^*$ and $Lambda^*$ resonances are predicted around 4.3 GeV in the hidden charm sector. We make estimates of production cross sections of these predicted resonances in $bar{p} p $ collisions for PANDA at the forthcoming FAIR facility.
