Description

This study focuses on the measurement of b-jet production in pp collisions at 13.6 TeV with the ALICE detector. The accurate identification of b-jets is crucial for understanding heavy-flavour quark production and fragmentation. This analysis concentrates on tagging beauty jets using the secondary-vertex method which excels in identifying long-lived hadrons containing a b quark by analyzing the secondary vertex of the hadron's decay and the primary vertex of the collision. In this work we focus on finding secondary vertices containing 3 prongs. Notably, this analysis takes advantage of the Run3 dataset, where updates to the Inner Tracking System (ITS2) have significantly improved the secondary-vertex resolution compared to Run2. This study presents the measurement of b-jet cross sections, highlighting the effectiveness of secondary vertex tagging techniques.
