    1831
    19 This model is an extension of the SM, featuring a vector leptoquark (''U,,1,,~('''3''','''1'''),,2/3,,''), a colored vector (''G'~('''8''','''1'''),,0,,''), and a SM singlet '' (''Z'~('''1''','''1'''),,0,,'') as new heavy mediators.  [[BR]]
    20 The 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.
     32This model is an extension of the SM featuring a vector leptoquark (''U,,1,,~('''3''','''1'''),,2/3,,''), a colored vector (''G'~('''8''','''1'''),,0,,''), and a SM singlet (''Z'~('''1''','''1'''),,0,,'') as new heavy mediators. An extension of the model including vector-like fermions coupling to the new heavy gauge bosons is included. [[BR]][[BR]]
     33The implementation of the heavy vector bosons is based on ''"High-p,,T,, Signatures in Vector-Leptoquark Models''" (arXiv:1901.10480). The extension of the model including vector-like fermions is based on ''"Maximal Flavour Violation: a Cabibbo mechanism for leptoquarks''" (arXiv:1808.00942) and ''"Reading the footprints of the B-meson flavor anomalies''" (arXiv:2103.16558).

    34 The model is loaded by merging the model files {{{SM.fr}}} (in StandardModel), {{{vector_LQ.fr}}}, {{{coloron.fr}}} and {{{Zprime.fr}}}. Alternatively, one can exclude the model files {{{coloron.fr}}} or {{{Zprime.fr}}} if the user is not interested in these mediators.  [[BR]]

Alternatively, one can exclude the model files {{{coloron.fr}}} or {{{Zprime.fr}}} if the user is not interested in these mediators.  [[BR]][[BR]]
    3549The 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). [[BR]]
    3650The NP interaction order has been set to 1, the same as QCD.

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