Description
Measurements of hadron production provide important insight about the quark and gluon fragmentation that are relevant for the simulation of kinematic distributions of high-energy collisions. The measurement of charged particle distributions using LHC proton-proton data collected at 13.6 TeV of centre-of-mass energy will be presented. The differences in the production with and without accompanying forward protons will be highlighted. In addition, the production of charged particle production in photo-nuclear interactions using lead-lead collisions at 5 TeV will be discussed and contrasted with photo-nuclear proton-lead events at the same collision energy. The spectra of correlated hadron chains are explored in p-p, p-lead, and lead-lead collisions and compared to the predictions based on the quantized fragmentation of a three-dimensional QCD helix string. Finally, the talk will describe a recent result of the search for Axion Light Particles utilising two photons and forward protons in the event.
