Software trigger in ALICE — •Victor Feuillard for the ALICE Germany collaboration — Physikalisches Institut, Ruprecht-Karls-Universität Heidelberg, Heidelberg, Germany

Since the beginning of Run3, ALICE has been recording data in a trigger less mode. As a consequence an enormous amount of data needs to be stored on disk. To mitigate for this situation, an offline trigger is applied on the data in order to reduce the volume of data stored in the long term. In this presentation, we will introduce the strategy implemented in ALICE to perform this offline filtering, as well as the result of the first two filtering campaigns in pp collisions at √s=13 TeV, regarding the data collected in 2022 and 2023
