	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.

	33	+* reproduce existing dijet-related experimental data (LL)
	34	+* implement applications in heavy-ion collisions (optional)
