Description

This work explores meson and isolated photon production in high-multiplicity proton-proton (pp) collisions at fixed energy and forward rapidities using the Color Glass Condensate (CGC) framework with running coupling Balitsky-Kovchegov (BK) solutions for the unintegrated gluon distribution. Self-normalized yields of these particles are studied as a function of charged hadron multiplicity and compared to experimental data when possible. We point that the simultaneous analysis of isolated photons and hadronic final states in high-multiplicity events may provide a test the CGC formalism and highlights the potential to disentangle initial- and final-state effects in high-energy hadronic collisions.
