For non-supersymmetric models one can use the following two options in the [Main Model File](/Main_Model_File"wikilink"):
-`NoU1Mixing = True/False;`, default: `False`, disables effects from gauge-kinetic mixing
-`NoU1Mixing = True/False;`, default: `False`, disables effects from gauge-kinetic mixing
-`IgnoreGaugeFixing=True/False;`, default: `False`, disables the calculation of the gauge fixing and ghost terms. Note, that this should just be done if a model is studied at tree-level. For a correct calculation of the loop corrections, the ghosts are needed. More information about the [gauge fixing terms and ghost interactions is given here.](/Gauge_fixing"wikilink")
