3.1 | 5 | **Introduction:** |
| 6 | |||
| 7 | Phenomenology in high-energy physics serves as a critical interface between theory and experiment. | ||
| |
4.1 | 8 | |
| |
3.1 | 9 | 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. |
| 10 | This transformation is at the heart of phenomenological work: it requires both analytical understanding and computational implementation. | ||
| 11 | |||
| 12 | 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. | ||
| |
4.1 | 13 | |
| |
3.1 | 14 | 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. |
| |
4.1 | 15 | |
| |
3.1 | 16 | 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. |
