Identified particle production in pp, p-Pb, and Pb-Pb collisions measured with ALICE at the LHC energies

Wednesday, 20 November 2013 from to (Mexico/General)
at ICN-UNAM ( Salón de Seminarios de Gravitación y Altas Energías )

Description
The ALICE detector has excellent Particle IDentification (PID) capabilities in the central barrel ($\lvert \eta \rvert$ $<$ 0.9). This allows hadron production to be measured over a wide transverse momentum ($p_{T}$) range, based on several sub-detectors and techniques. The particles are identified by one or more of; their specific energy loss (d$E$/d$x$), the time of flight, the Cherenkov angle or their characteristic weak decay topology.

Results on identified particle spectra and production yield ratios at
mid-rapidity measured by ALICE in different colliding systems (pp, p-Pb and Pb-Pb)  will be presented and the similarities among them will be discussed. For Pb-Pb collisions the nuclear modification factor as a function of $p_{T}$  will be shown for different collision centralities.
