Physics 872 Nuclear Physics II
Instructor: Simonetta Liuti (sl4y@virginia.edu)

Drawing adapted from Heidi Schelmann (Northewestern U.)

Aim: To give you the tools to both understand other people's calculations and experimental proposals, and to do your own calculations and make your own proposal(s) of new experiments at present and future facilities.

Progress:

• First Half of September

  Review of Inclusive ep Scattering:

• Covariant Formalism: calculation of Feynman diagram for inclusive lepton-proton scattering.
