12 -**Introduction:**
13 -
14 -Phenomenology in high-energy physics serves as a critical interface between theory and experiment.
15 -While theoretical models—particularly those based on Quantum Chromodynamics (QCD)—allow us to predict observables such as differential cross-sections, these predictions must be transformed into concrete numerical results before they can be compared to experimental data.
16 -This transformation is at the heart of phenomenological work: it requires both analytical understanding and computational implementation.
17 -
18 -In this project, the student will learn how to translate theoretical expressions for differential cross-sections into numerical simulations, calculate relevant observables, and compare these results with real-world data from high-energy experiments such as those at the LHC or RHIC.
19 -The focus will be on inclusive jet and hadron production, with the possibility of exploring more complex observables such as dijet correlations or extending the analysis to heavy-ion collisions.
20 -Through this hands-on experience, the student will develop practical skills in numerical computing, gain insight into the logic of perturbative QCD calculations, and understand how phenomenological tools connect theoretical predictions with experimental measurements.
