k_S^0, Λ, and ͞Λ, pT spectra in pp collisions at √s = 7 TeV, measured with the ALICE experiment at LHC
Author
Summary, in English
This thesis presents a study of L, ¯L, and K0
s particle (generically referred to as V0 particles)
production measured by the ALICE experiment located at LHC, CERN, in protonproton
collisions at a center of mass collision energy of
p
s = 7 TeV. The particles are
reconstructed via their V0 decay topology, which can be done due to the excellent tracking
performance of the Time Projection Chamber detector. The V0 invariant yields, as
well as the pT dependence of the L/K0
s and ¯L/L ratios, are produced and analyzed. In
addition to being one of the first measurements of these particles in pp collisions at this
energy, the results are important as a reference for studies of lead-lead collisions, where
the yield and ratio dependencies of transverse momentum are expected to change due
to a recombination mechanism during the hadronization of the new quark matter state
created in heavy ion collisions: the quark gluon plasma.
