Measurements of prompt-charm-production-cross-sections in pp collisions at LHCb for Run 3 — Rowina Caspary, Giulia Frau, Paul André Günther, Stephanie Hansmann-Menzemer, and •Maurice Pierre Morgenthaler — Physikalisches Institut, Ruprecht-Karls-Universität Heidelberg, Heidelberg, Germany
The LHCb experiment at CERN plays a leading role in the study of bottom and charm quark physics. The experiment was heavily upgraded for Run 3, necessitating studies to validate its performance. In this talk, we will present one of the initial Run 3 analysis which delivers interesting first physics results and provide a detailed understanding of the upgraded experiment simultaneously. The data used to measure the prompt-charm-production-cross-sections is taken in pp-collisions in 2023 at a center-of-mass energy of 13.6 TeV corresponding to an integrated luminosity of 47 pb−1. Using bins of charm-hadron transverse-momentum and rapidity, the cross-sections of D0, D+, Ds+ and D∗ + mesons are measured.
