Charm mesons production asymmetries at LHCb in Run 3 — •Luca Balzani1, Serena Maccolini2, and Dominik Stefan Mitzel1 — 1TU Dortmund University, Dortmund, Germany — 2CERN, Geneva, Switzerland
Ahead of Run 3 of the LHC, the LHCb detector was profoundly upgraded to leverage the programmed increase in luminosity. Studying the features of the upgraded detector is of paramount importance in order to reliably perform measurements.
Production asymmetries are ideal candidates to investigate the characteristics of the new LHCb detector. These observables depend on the colliding system characteristics but shall not be influenced by experimental effects. Therefore, having these latter contributions under control is essential to perform a consistent measurement. Precise measurements of production asymmetries also allow for a better understanding of QCD models used in Monte Carlo generators, especially in the high-rapidity region. The production asymmetry for neutral charm meson has been measured for the first time in proton-proton collisions at the LHC energies and is part of the first published result from LHCb with Run 3 data. This contribution will discuss the general strategy and the techniques used for the measurement, providing some insights on the characteristics of the new LHCb Run 3 data.
