    18 The SMEFT is constructed out of a series of SU(3),,C,, × SU(2),,L,, × U(1),,Y,, invariant (local and analytic) higher dimensional operators L,,6,,, L,,7,,, ... built out of the SM fields.[[BR]]
    19 The SMEFTsim package provides a complete implementation of the dimension-6 Lagrangian adopting the Warsaw basis [https://arxiv.org/abs/1008.4884/ arXiv:1008.4884]

    21 The SM Lagrangian is extended with the inclusion of the complete set of baryon-number-conserving operators of the Warsaw basis and of the SM loop-induced  Higgs couplings to gg, γγ and Zγ. [[BR]]
    22 Importantly, field rotations required to have canonically normalized kinetic terms and parameter redefinitions following from the choice of an input parameters set are automatically applied in the Lagrangian.

    2827* The flavour general case
    2928* The U(3)^5^ flavor symmetric case, with possible non-SM CP-violating phases
    30 * A linear Minimal flavor violation (MFV) ansatz, in which non-SM CP-violating effects are neglected, but flavor-violation spurion insertions are allowed in quark currents
     29* A linear Minimal flavor violation (MFV) ansatz [Gino's paper], in which non-SM CP-violating effects are neglected, but linear flavor-violating spurion insertions are allowed in quark currents

    3231For each model it is possible to choose between two input parameters sets for the electroweak sector, namely:
    3332* α scheme: {α,,em,,, m,,Z,, , G,,f,,}
    34 * m,,W,, scheme: {m,,W,,, m,,Z,, , G,,f,,}
     33* m,,W,, scheme: {m,,W,,, m,,Z,, , G,,f,,}

    3637Two independent models sets (A and B) are supplied. Each set contains a main file, a number of subroutines and restriction files.
