Default loading of the model 24 ==== Restriction cards ==== 25 Because of the mixture of LO/NLO compatible operators included in the model, restriction cards must be used to access the SMEFT interactions. 26 27 Default loading of the model 25 28 {{{ 26 29 > import model SMEFTatNLO_U2_2_U3_3_cG_4F_LO_UFO … … 39 42 This invokes a restricted set of operators for which the required counterterms are implemented. 40 43 44 ==== Coupling orders ==== 45 41 46 We recommend specifying the full {{{QCD}}}, {{{QED}}} and {{{NP}}} orders for process generation. 42 47 … … 47 52 }}} 48 53 Generates the NLO QCD top pair production process including the QCDinduced SM and the SMEFT contributions. 54 55 ==== Excluding operators ==== 56 57 We recommend avoiding setting values of Wilson coefficients to 0 when computing at NLO using MadGraph5_aMC@NLO. 58 59 Operators should either be removed explicitly with restriction cards or set to a very small nonzero value, e.g., 1e10 49 60 === Model Files === 50 61 * [https://feynrules.irmp.ucl.ac.be/attachment/wiki/SMEFTatNLO/SMEFTatNLO_U2_2_U3_3_cG_4F_LO_UFO.20190812.tgz SMEFTatNLO_U2_2_U3_3_cG_4F_LO_UFO.tgz] : archive of UFO model  4 fermion and c,,G,, operators at LO, U(2)^2^ x U(3)^3^ flavor symmetry
