Abstract
1. Given the Lagrangian for the Standard Model, the Z boson couples to quarks and leptons in the Dirac basis proportional to the vector and axial vector coupling constants, g V and g A [Eq. (2.17)]. Evaluate g V , g A for up quarks and down quarks. 2. Write the first term in Eq. (2.20) using Dirac notation.

- 1.
We assume that there are only two Wilson lines, W 3 in the SU(3) torus and W 2 in the SO(4) torus.
