Abstract: In this paper, we investigate the transverse momentum spectra of charged particles in proton–proton collisions at the LHC using detailed event-by-event simulations with the PYTHIA 8 event generator. Rather than relying solely on average observables such as the mean transverse momentum, we analyse the full shape of the spectra across different charged-particle multiplicity intervals. Our results show that significant variations in spectral shape occur with increasing multiplicity, revealing a transition from soft to hard processes that is not captured by global mean values. Comparisons with other commonly used Monte Carlo models, including Herwig 7 and EPOS 4, demonstrate that while the mean values are broadly consistent across generators, the underlying spectral shapes differ.
