Important Message for Mid term exam:

The loop diagrams shall ONLY be calculated in Feynman gauge for the gluon propagator.

In third lin of problem 3, "photon" should be replaced by "gluon"

JOE

The MId Term Exam Problems are now available

Next week there will be lecture(s) tuesday 4 march (continues with RGE for QCD)

The Mid-term exam will be on this web page monday morning 3.march.

There will be no lectures thursday 6. and tuesday 11. march

This week I will continue to tal about the renormalization group

This week I will continue to tal about the renormalization group

Tomorrow I will start to talk about the renormalization group Equations (RGE);- in first case examplified for  massless Phi^4 theory

Exercises( The Mid-term for 2013 ) is now available

Next week 11-13 febr, there will be more on renormalization (vertex correction etc), ward identities, soft photon bremsstrahlung, optical theorem etc

This week (4-6. feb) I will talk on dimension regularization- and vacuum polarization.

JOE

This week I will talk on the electron (fermion) self energy,- and afterwards on vacuum polarization.
