Abstract: Investigating mechanisms for baryon and meson production at LHC energies with the ALICE experiment.

Speaker: Boris Hippolyte for the ALICE Collaboration Abstract: Several mechanisms are expected to compete for the production of hadrons at the LHC. In order to anticipate the study of baryon production in both elementary and nuclear collisions at multi-TeV energies, we propose here to discuss both recent model extrapolations and experimental capabilities for identified species. Starting from the Lund model and in-vacuo string fragmentation, the possibility of studying junction topologies will be first presented. Secondly, we will focus on experimental observables that could be used for investigating multi-parton interactions and help understanding the "underlying event" content in the first p+p collisions at the LHC.
