v3 v4 21 21 22 22 === Synopsis === 23 Th is set of UFO libraries enables one to simulate the Weinberg operator in high-energy scattering and resonant decay processes up to next-to-leading order in QCD.23 The {{{SMWeinberg}}} UFO libraries allows one to simulate the Weinberg operator in high-energy scattering and resonant decay processes up to next-to-leading order in QCD when used in conjunction with event generators, like {{{MadGraph5_aMC@NLO}}}. 24 24 25 25 26 26 === Full Description === 27 This model file is constructed in the context of the Standard Model (SM) Effective Field Theory (SM EFT), and extend the SM Lagrangianby gauge-invariant operators up to dimension {{{$d=5$}}}. In the canonical representation the Lagrangian is given by27 This model file works in the context of the Standard Model (SM) Effective Field Theory (SM EFT), where the SM Lagrangian is extended by gauge-invariant operators up to dimension {{{$d=5$}}}. In the canonical representation the Lagrangian is given by 28 28 {{{ 29 29 #!latex … … 41 41 }}} 42 42 where 43 {{{$\Lambda$}}} is the EFT cutoff scale, 44 {{{$C^{\ell\ell'}_5$}}} is the flavor-dependent Wilson coefficient in the flavor basis, 43 {{{Lambda}}} is the EFT cutoff scale [GeV], 44 {{{#!latex 45 $C^{\ell\ell'}_5$ 46 }}} 47 {{{#!latex $C^{\ell\ell'}_5$}}} 48 is the flavor-dependent Wilson coefficient in the flavor basis, 45 49 and the the SU(2)-invariant product {{{$\Phi\cdot \overline{L^c} = \Phi^i\varepsilon_{ij} \overline{L^{cj}}$}}} is fixed by {{{$\varepsilon_{12}=1$}}}. 46 50
