Strange and charmed baryon pair productions in proton-antiproton collisions are studied in the effective Lagrangian and Regge approaches. Unknown parameters of both models are determined from the comparison with the existing data for strangeness productions. Then, we predict charm production cross sections by extrapolating the amplitudes for strangeness productions to those for charm. As a result, the total cross sections are about 10 to 10 times smaller than those of strangeness productions, depending on the final states. By using the known total cross sections for strangeness, similar to 10 b for and, similar to 10 b for , the total cross sections for charm productions are predicted to be similar to 10 b for , similar to 10 b for , and similar to 10 b for . Our results can be tested in the future experiments at ANDA.
