1) Structure of matter particles and interactions in the Standard Model

2) Mandelstam variables on example of 2->2 process e+e- -> mu+ mu-

3) Fermi's Golden Rule formula for transition rates.
   Could you write down this formula and explain components.
   Could you recall formula for
      --> scattering cross-section in center-of-mass frame
      --> invariant differential cross-section in the lab frame

4) Accelerators: basic principles for operating circular colliders,
   which components are mandatory. 
   Example of luminosity available is related to parameters of
   the machine (beam size, frequency, etc.) ?
