Homework and Tests for Quantum Field Theory

Dr. Kaplunovsky's Class

All assignments are available in 4 formats, use whichever you like (or whichever your software likes).

TeX
Plain TeX (not LaTeX) source of the problem set. Needs phyzzx macros.
DVI
Device-independent TeX output.
PDF
Adobe Portable Document Format. Uses scalable fonts, so should work for both screen viewing and printing.
PS
Postscript. Uses scalable fonts, so should work for both screen viewing and printing.
Source
TeX source, DVI and all the eps pictures tarred together and gzipped. This format replaces separate TeX and DVI formats when eps pictures are present.

Exams

  • Mid-term exam (tex, dvi, pdf, ps), due in class, on Wednesday October 29.
  • End-term exam (tex, dvi, pdf, ps), due December 11 by 5PM.
    Error note: the printed version of this exam had a sign error in eq. (F.12) and a missing factor of i in eq. (F.11). The on-line version was corrected at 14:53 on 2003-12-08; please reload.
    Note: In problem 1 you must calculate the whole shmeer: First, calculate M(2 charged —> 2 neutral); second, use the wave function of the bound state and calculate M(bound —> 2 neutral); and finally calculate the decay rate.
    Note: In problem 2(a) you may take the basic scalar propagator for granted, but you should explain the arrows in eqs. (F.7–9).
