Initial tuning of PYTHIA to the first data recorded by LCHb — •Dmitry Popov, Osvaldo Aquines, Markward Britsch, Florin Maciuc, and Michael Schmelling — Max Planck Institute for Nuclear Physics in Heidelberg, Germany

The acceptance of the LHCb in the pseudorapidity range 2< eta <5 is complementary to that of the other larger LHC experiments. Inclusive distributions as a function of rapidity, pseudorapidity and transverse momentum for positive and negative charged particles based on the first data recorded by the LHCb detector are compared to minimum bias Monte Carlo predictions. A first tuning of fragmentation paremeters for the PYTHIA generator will be presented.
