This study investigates dijet and neutral pion production in high-energy nuclear collisions in the LHCb detector. The obtained measurements offer crucial insights into Quantum Chromodynamics
(QCD), understanding of parton distribution functions, nuclear structure, and particle production dynamics. Specifically, the nuclear modification factor for neutral pions in proton-lead collisions at 8.16 TeV reveal notable first evidence enhancement in the backward region providing constraints on models of nuclear structure. Furthermore, the inclusive 𝑏 ̄𝑏 and 𝑐 ̄𝑐-dijet production cross-sections in the forward region of pp collisions at 13 TeV align with next-to-leading order theoretical predictions. These findings on dijet and neutral pion production offer complementary perspectives on PDFs and nuclear structure, which are crucial for comprehending QCD dynamics in high-energy nuclear collisions and refining theoretical models.
