Reconstruction of Beauty Jets in Proton-Proton Collisions at √s=13 TeV with ALICE — •Katharina Garner for the ALICE collaboration — Westfälische Wilhelms-Universität Münster, Germany

When traversing the Quark-Gluon Plasma (QGP), partons lose energy via collisional and radiative processes. For both types of processes, the amount of lost energy depends on the particle mass and manifests in a reduced jet multiplicity in heavy-ion collisions with respect to proton-proton collisions, for which no QGP is expected to form. A detailed knowledge about not only the light-flavour but also the charm and bottom jet production in proton-proton collisions is thus inevitable for further investigations on particle energy losses. Since B mesons have much larger life-times compared to other hadrons, signed impact parameter spectra, as a measure for the distance between particle tracks and the primary vertex, offer a great opportunity to investigate the bottom jet production. First steps of an analysis on signed impact parameter distributions for tracks from within light-flavour, charm- and bottom jets in 13 TeV proton-proton collisions are presented.
