    Photon mass in superconductors

    If the symmetry breaks here, does that mean the standard model is already wrong?

    It's an effective mass, not a rest mass. The Standard Model give the free photon a zero rest mass, not a zero effective mass. We already see photons forming a quasiparticle with an effective mass (the polariton).

    Ok thanks for the clarifications.
