Phenomenology of Fundamental Interactions
The
Graduate School in Physics of
Torino University
organizes different Ph.D. Programmes in Theoretical Physics that are related
to the research lines pursued within the
Department of Theoretical Physics and the
INFN Sezione di Torino
and are linked to international collaborations both at the scientific and
teaching level.
Phenomenology of Fundamental Interactions consists of two
distinct Ph.D Programmes
- Physics at Colliders
- Astroparticle and neutrino Physics
The different curricula are activated on a yearly basis (November-May)
depending on the profile of the selected Ph.D. students.
The courses are by default in English.
Ph.D. Programmes on Phenomenology of Fundamental
Interactions
We invite external Ph.D. students, in particular from neighboring
universities, to participate in our Programmes that are activated
on a yearly basis as advertised on the net.
The detailed plan of the introductory courses will depend on the profile
of the students. These are assumed to have followed at least three preliminar
courses during their training, equivalent to the following three given at
Torino University:
-
Introduction to QFT (50 hours)
(G.Passarino)
-
Introduction to Renormalization (40 hours)
(G.Passarino/R.Pittau)
-
Phenomenology of Fundamental Interactions (50 hours)
(A.Bottino/
N.Fornengo)
Students who do not have these courses in their previous training will have
to take them during their Ph.D programme.
The remaining parts of the detailed plans of study for the two
Ph.D. Programmes are as follows:
Physics at Colliders

Ph.D. students that have an interest in this field will have to follow
a teaching path composed by:
