Ultraforward particle production from color glass condensate and Lund fragmentation

Abstract: We present an analysis of data on single inclusive pion production measured by the LHCf collaboration in high-energy proton-proton and proton-nucleus at ultra-forward rapidities, 8.8 ≤ y ≤ 10.8. We also analyse forward RHIC data for calibration purposes. Our analysis relies on the use of a Monte Carlo event generator that combines a perturbative description of the elementary scattering process at partonic level based on the hybrid formalism of the Color Glass Condensate with an implementation of hadronization … Show more

“…Refs. [90,91] where the Lund string model based Monte Carlo methods were used to describe the fragmentation processes. A more realistic production mechanism for the jet formation would also motivate to use a more realistic jet finding algorithm to distinguish jets that are merged from the other jets whose energy is not included in the total energy of the observed jet.…”

“…The AAMQS predictions [24] for the forward jet spectra are also obtained using hybrid factorization. At the parton level, the AAMQS model generates quarks and gluons from gq → q and gg → g hard processes, along with initial-and final-state radiation based on DGLAP evolution.…”

“…For x ≈ 10 −6 , the anticipated saturation scale in a lead nucleus is approximately 10 GeV 2 and, thereby, enhanced signals of gluon saturation are expected when colliding lead ions compared to protons at the LHC. Besides being a major research topic in its own right, parton saturation is also an important theoretical ingredient for describing the initial state of heavy ion collisions [23], and for understanding cosmic ray data [24].…”
