     17=== Description of the model ===
     18
     19This model is an extension of the SM, featuring a vector leptoquark (''U,,1,,~('''3''','''2'''),,2/3,,''), a colored vector (''G'~('''8''','''1'''),,0,,''), and a ''Z' '' (''Z'~('''1''','''1'''),,0,,'') as new heavy mediators.
     20
     21The implementation of the model is based on ''"High-p,,T,, Signatures in Vector-Leptoquark Models''" (arXiv:1901.10480). If you use our model file please cite this reference.

    1533=== Instructions ===
    1634
    17 This implementation corresponds to the vector leptoquark model (''U,,1,,'') described in arXiv:1901.10480
     35The model is loaded by merging the model files {{{SM.fr}}}, {{{vector_LQ.fr}}}, {{{coloron.fr}}} and {{{Zprime.fr}}}. Alternatively, one exclude the model files {{{coloron.fr}}} or {{{Zprime.fr}}}, if the user is not interested in these mediators.
     36
     37The implementation allows for the use of the Feynman gauge in the SM.The switch between the two gauge is achieved via {{{FeynmanGauge = True/False}}} (see StandardModel).

    26 === UFO models ===
     50An alternative  Feynrules implementation for the vector leptoquark model (but with interactions to left-handed SM fermions only) is available in https://lqnlo.hepforge.org. We have cross-checked our leptoquark implementation (with ''β,,33,, = 0'') against this one, finding a perfect agreement between the two.
