Homework Help: Find the gauge transformation of a Lagrangian

  1. Oct 18, 2015 #1
    1. The problem statement, all variables and given/known data
    The lagrangian is given by:
    [tex] L = -\frac{1}{4} F^2_{\mu \nu} + (\partial_{\mu} \phi_1 - m_1 A_{\mu})^2 + (\partial_{\mu} \phi_2 - m_2 A_{\mu})^2 [/tex]

    2. Relevant equations
    Find the gauge transformation of the fields that corresponds to a symmetry.
    Find the combination of scalar fields which couples to A_mu.

    3. The attempt at a solution
    I am clueless here, any idea would be great.
