Charm Production in Antiproton-Proton Annihilation
Abstract We study the production of charmed mesons (D) and baryons ($ Λ_{c} $) in antiproton-proton $${(\bar{p}p)}$$ annihilation close to their respective production thresholds. The elementary charm production process is described by either baryon/meson exchange or by quark/gluon dynamics. Effects...

| 520 | |a Abstract We study the production of charmed mesons (D) and baryons ($ Λ_{c} $) in antiproton-proton $${(\bar{p}p)}$$ annihilation close to their respective production thresholds. The elementary charm production process is described by either baryon/meson exchange or by quark/gluon dynamics. Effects of the interactions in the initial and final states are taken into account rigorously. The calculations are performed in close analogy to our earlier study on $${\bar{p}p \to \bar{\Lambda} \Lambda}$$ and $${\bar{p} p \to \bar{K} K}$$ by connecting the processes via SU(4) flavor symmetry. Our predictions for the $${\bar{\Lambda}_c \Lambda_c}$$ production cross section are in the order of 1 to 7 mb, i.e. a factor of around 10–70 smaller than the corresponding cross sections for $${\bar{\Lambda} \Lambda}$$ However, they are 100 to 1000 times larger than predictions of other model calculations in the literature. On the other hand, the resulting cross sections for $${\bar{D} D}$$ production are found to be in the order of $ 10^{−2} $ – $ 10^{−1} $μb and they turned out to be comparable to those obtained in other studies. | ||

Charm Production in Antiproton-Proton Annihilation |
| abstract |
Abstract We study the production of charmed mesons (D) and baryons ($ Λ_{c} $) in antiproton-proton $${(\bar{p}p)}$$ annihilation close to their respective production thresholds. The elementary charm production process is described by either baryon/meson exchange or by quark/gluon dynamics. Effects of the interactions in the initial and final states are taken into account rigorously. The calculations are performed in close analogy to our earlier study on $${\bar{p}p \to \bar{\Lambda} \Lambda}$$ and $${\bar{p} p \to \bar{K} K}$$ by connecting the processes via SU(4) flavor symmetry. Our predictions for the $${\bar{\Lambda}_c \Lambda_c}$$ production cross section are in the order of 1 to 7 mb, i.e. a factor of around 10–70 smaller than the corresponding cross sections for $${\bar{\Lambda} \Lambda}$$ However, they are 100 to 1000 times larger than predictions of other model calculations in the literature. On the other hand, the resulting cross sections for $${\bar{D} D}$$ production are found to be in the order of $ 10^{−2} $ – $ 10^{−1} $μb and they turned out to be comparable to those obtained in other studies. © Springer-Verlag 2010 |
