About Lorenzo Magnea

I am a theoretical physicist, currently working in Torino, Italy, where I am a Professor at the local Department of Physics.

Research

• My main research interest is in particle physics, and in particular in QCD, 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 Large Hadron Rap by alpinekat. If you want to know more, watch some excellent videos by PBS, more videos , 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.

Teaching

• 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 2006 and 2012, I taught Introduction to Group Theory for the Master's Degree in Physics. Here is the official web page of the class.
  • Amazingly, also Group Theory can inspire sentimental songs ... enjoy the video of the Klein Four ``group'', singing Finite simple group of order 2.

• In 2011, I taught Introductory Electromagnetism for the Bachelor's Degree in Materials Sciences, working with Nicolao Fornengo and Igor Pesando.

• 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 Fiorenza Donato, who has now taken over.

• In the past I taught Introductory Quantum Mechanics for the Math Degree program and for the Advanced School for Teachers.

• Advanced Lectures on the Infrared structure of Perturbative QCD, given at ETH in Zurich, February 2010, and as SUPA Distingushed Visitor to Edinburgh and Glasgow Universities in January 2011. Handwritten notes: Lecture 1, Lecture 2, Lecture 3, Lecture 4.

• Lectures on Perturbative QCD at the Workshop ``Signaling the Arrival of the LHC Era'', ICTP Trieste, december 2008 (pdf).

• Lectures on Perturbative QCD at the National School of Theoretical Physics of the University of Parma updated in 2008 for WHEPP X in Chennai. Available in italian (pdf), and in english (pdf).
