| Περιγραφή: | During the second long shutdown of the Large Hadron Collider (end of 2018 to middle of 2022), the ALICE detector was the subject of a complete reworking of its detector, reconstruction and analysis software, to prepare for the analysis of collisions happening at an increased interaction rate and recorded continuously, without trigger. The recording in October 2021 of the pilot beam proton-proton collisions at sqrt{s} = 900 GeV and the production of Monte Carlo data simulating those beam conditions allowed an extensive test of this new detector as well as of the reconstruction and analysis tools. This work focuses in this context on the analysis of the V0 decays K0S and Lambda in a Monte Carlo simulation of the pilot beam collisions. Those decays are building blocks for the analysis of strange decays in general, a valuable probe of the quark-gluon plasma. Their transverse momentum spectra are computed from the data reconstructed using the new analysis software, and compared to the initial spectra generated by the simulation. The analysis suite succeeds in reproducing the generated spectrum. The lower reconstruction efficiency compared to analyses done before the upgrade prompted a loosening of the reconstruction cuts despite leading to additional computing load. An imperfection in the calibration of the first preliminary results from real data is also observed. |
