Abstract: In this thesis, measurements of different charged-particle distributions performed with the CMS detector in proton-proton collisions at a centre-of-mass energy √s = 13TeV are presented.In particular, the charged-particle pseudorapidity distributions, also referred to as charged-particle pseudorapidity densities, the multiplicity distributions of charged particlesper event, and different transverse-momentum distributions corresponding to all chargedparticles, the leading charged-particle, and the integrated spectrum of the latter are presented.The charged-particles are selected with transverse momenta pT > 0.5 GeV in the range |η| < 2.4. The data are corrected for the different detector effects such as resolution andefficiency. The measured distributions are presented for four different samples corresponding to an Inclusive event sample, an Inelastic-enhanced event sample, a sample dominated bynon-single diffractive dissociation events (NSD-enhanced sample), and a sample enriched by single-diffractive dissociation events (SD-enhanced sample). The measurements presented in this thesis provide extensive and unique insights into low energy exchange processes that dominate the proton-proton interactions. The rich variety ofdistributions presented for different event samples, especially those enhanced in diffractive processes, are valuable sources of information to understand the transition from the perturbative to the non-perturbative regions and to adjust the model parameters present in modern MC event generators.5
