LHCb for astroparticle physics: Prompt production of charged particles — Johannes Albrecht1, •Julian Boelhauve1, Hans Dembinski1, and Michael Schmelling2 — 1TU Dortmund University, Dortmund, Germany — 2Max Planck Institute for Nuclear Physics, Heidelberg, Germany
A long-standing issue in the field of cosmic-ray research is the discrepancy in the number of muons produced in high-energy air showers between observations and simulation, which is referred to as the Muon Puzzle. Precision measurements of hadron production in the forward region are required in order to validate and improve the hadronic-interaction models used in the simulation of air showers, aiming at solving the Muon Puzzle. For this, measuring the differential cross-section of prompt production of long-lived charged particles as a function of transverse momentum and pseudorapidity is of great importance.
An analysis in which this differential cross-section has recently been determined in proton-proton collisions recorded with the LHCb experiment at a centre-of-mass energy of 13 TeV is presented in this talk. Moreover, extensions of the analysis towards a measurement of prompt production of identified hadrons are described.
