CAMPANELLI1	The physics of jets at the Large Hadron Collider
Type	Experimental
#students	2
Orientation	Why is the scientific problem of interest at all? Particle colliders provide access to the highest energies and shortest distances, allowing us to extend the frontiers of knowledge of the fundamental forces and particles of the universe. Hadronic jets in a high-energy collider can be initiated by quarks, gluons or hadronic decays of heavy objects. Distinguishing between these topologies opens new doors to the understanding of the collisions from the LHC, and allows for the possibility of looking for new physics
How	How is the research going to shed light on the given problem?. The project aims at assessing the performance of various techniques developed to study the sub-structure of hadronic jets, and distinguish various production modes. The student(s) will be part of an active group studying jet substructure in the Atlas experiment
What	What is the specific thing that the student will do, and how does it fit inside the overall project? The student will analyse simulated and real data from the Atlas experiment, applying various techniques to distinguish various kinds of jets, and assess their performance.
Special Knowlegde	It mainly requires programming, statistical data analysis, and attending meetings.
