Abstract
The production of the D0 meson in pp collisions at √s = 7TeV through its hadronic decay in Kπππ, using the ALICE detector, is measured. By applying a series of topological cuts and PID selections, signal peaks in the invariant mass distribution M(Kπππ) have been found in different pT bins, ranging from 4.5 to 25 GeV/c. After performing corrections for efficiency, acceptance and feed-down from beauty contribution, differential direct production yield and cross section can be computed and compared to pQCD theoretical predictions which show a good agreement for the shape of the pT-differential cross section.
