3 Solved Problems On Quantum Field Theory I Assignment 10 Phy 396kо The introduction to quantum field theory is a two semester course. content wise, this is a continious 29 week long course, but for administrative purposes it is split in two: phy 396 l quantum field theory ii, usually taught in the spring. physics wise, the split is rather arbitrary, so students seriously interested in the quantum field. Phy–396 k. problem set #13. due december 2, 2004 (last class day). 1. consider the bhabha scattering e−e → e−e . in qed, there are two tree level feynman diagrams contributing to this process. Phy–396 k l. solutions for problem set #12. problem 1: note the correct muon decay amplitude m (µ− → e−νµν̄e) = gf√ 2 [ ū (νµ) (1− γ5)γαu (µ−) ] × [ ū (e−) (1− γ5)γαv (ν̄e) ] . (1) the complex conjugate of this amplitude m∗ = gf√ 2 [ ū (µ−)γβ (1 γ5)u (νµ) ] × [ v̄ (ν̄e)γβ (1 γ 5)u. Qft ps4 solutions: free quantum field theory (22 10 18) 3 the quick and dirty way here is to remember that these integrals here are part of an operator expression coming from commutators even if it is a unit operator. to evaluate these expressions the operator must act on something. so you should let your expression act on a dummy function f(p).

The various terms, parameterized by λ n, fall into three different categories. [λ 3] = 1: for this term, the dimensionless parameter is λ 3 e, where e has dimensions of mass. typically in quantum field theory, e is the energy scale of the process of interest. this means that λ 3. Quantum field theory assignment 7 solutions | phy 396k, assignments for physics. phy–396 k. solutions for problem set #7. problem 1 (a): γµγν = ±γνγµ where the sign is ‘ ’ for µ = ν and ‘−’ otherwise. hence for any product Γ of the γ matrices, γµΓ = (−1)nµΓγµ where nµ is the number of γ ν 6=µ factors of.
