ADVANCED PARTICLE PHYSICS 2
Academic Year 2017/2018 - 2° Year - Curriculum FISICA NUCLEARE E SUB-NUCLEARECredit Value: 6
Scientific field: FIS/04 - Nuclear and subnuclear physics
Taught classes: 42 hours
Term / Semester: 1°
Learning Objectives
The course is aimed to provide an advanced knowledge of the particle physics phenomenology. In particular, the course is aimed to critically discuss the latest achievements in particle physics analysing the results obtained at LEP, TeVatron and LHC. The student will acquire a critical knowledge about the Standard Model, the Higgs mechanism and the possible extension of the Standard Model, the research methodology and the obtained results.
