We evaluate the cross sections for charmed hadron production from proton-proton reactions $pp\to\bar D^0p\Lambda_c^+$ and $pp\to\bar D^{*0}p\Lambda_c^+$ using a hadronic Lagrangian. With empirical coupling constants and cutoff parameters in…

It is usually assumed that the production of baryons in $B$ meson decays is induced primarily by the quark level process $b\to c\bar ud$, where the charm quark hadronizes into a charmed baryon. With this assumption, the $\Lambda_c$ momentum…

Using the Quark-Gluon Strings Model (QGSM) combined with Regge phenomenology we consider the reactions $\pi^- p \to K^0 \Lambda$ and $\pi^- p \to D^- \Lambda_c^+$ which are dominated by the contributions of the $K^*$ and $D^*$ Regge…

It is shown that the D--meson, whose light quark is the initial-pion valence quark and whose charmed quark is produced in annihilation of valence quarks and has got a large enough momentum, is really a leading meson in reactions like $\pi^-…

We investigate the possibility to study the charmed baryon $\Lambda_c(2940)$ by kaon-induced reaction on a proton target. By assuming the $\Lambda_c(2940)$ as a $pD^{*0}$ molecular state with spin-parity $J^{p}=1/2^{\pm}$, an effective…
