About Lorenzo Magnea
I am a theoretical physicist, currently working in
where I am a Professor at the local
My main research interest is in
particle physics, and in particular in
especially in the perturbative regime.
As you may know, this is the physics of
LHC , one of the greatest scientific experiments
of all time. LHC will
not produce dangerous
black holes, but great results instead! For a
musical explanation, listen to the
Rap by alpinekat.
If you want to know more, watch some excellent
by PBS, more
, also excellent, by BBC News,
and a special on the
New York Times where I especially
recommend a nice article by Brian Greene. The LHC recently discovered a new particle, with all the properties of the Standard Model Higgs boson: a great
leap forward in our understanding of the Universe. Also for the Higgs boson, a fun musical explanation is available!
Here you find an introductory lecture on particle
physics, in italian and for the general public, which I gave at the Scuola di Fisica of the University of Torino, then for the project BraVinRicerca in the beautiful town of Bra, and finally in the conference series SeralMente at the Majorana high school in Grugliasco. An english version is available here.
- Here are some problems I am currently working on
- Infrared and collinear divergences in perturbative QCD.
- String--derived methods for quantum field theory calculations.
- Soft gluon resummations and power corrections for collider observables.

- Since 2016, I teach Physics for Citizens, an introductory physics class for non-science majors, inspired by the book Physics for Future Presidents, working with Giuseppe Tipaldo, a media scientist at the Department of Cultures, Politics and Society.
- Since 2015, I teach TIF, a short introductory course on symbolic computing software, for the Bachelor's Degree in Physics.
- Since 2014, I teach Advanced Quantum Field Theory for the Master's Degree in Physics.
- Between 2012 and 2015, I taught Introductory Physics for the Bachelor's
Degree in Chemistry, in collaboration with Simonetta Marcello.

- Between 2007 and 2010, I taught Phenomenology of Fundamental
Interactions (basics of the Standard Model), for the Master's Degree in
Physics of Fundamental Interactions, together with

Math Degree program and
for the Advanced School for Teachers.
