Abstract

We present the preliminary p_t differential cross section in pp collisions of the D_s⁺ meson measured in the mid-rapidity region of ALICE through the D_s⁺ → K⁺K⁻π⁺ decay channel with an integrated luminosity of 4.8 nb⁻¹. The ratios between all the D meson preliminary p_t differential cross sections measured in the ALICE experiment (D_s⁺, D⁰, D⁺, D*⁺) are also presented and compared with the results of other experiments.
