v25 v26 12 12 * IPHC Strasbourg / University of Strasbourg 13 13 * benjamin.fuks@iphc.cnrs.fr 14 * Celine Degrande 15 * IPPP University of Durham 16 * celine.degrande@durham.ac.uk 14 17 15 18 === Model Files === … … 21 24 * [/feynrules/attachment/wiki/StandardModel/Cabibbo.rst Cabibbo.rst]: 3rd generation mixing is off. 22 25 === Instructions === 23 The Standard Model (SM) is implemented in both Feynman and unitary gauge. A switch {{{FeynmanGauge}}} has been created. To switch between the two simply set {{{FeynmanGauge = True/False}}} inside your mathematica notebook after loading the model but before doing any calculations with it (finding vertices for example.) {{{FeynmanGauge}}} is set to {{{False}}} by default. 26 The Standard Model (SM) is implemented in both Feynman and unitary gauge.

To switch between the two simply set {{{FeynmanGauge = True/False}}} inside your mathematica notebook after loading the model but before doing any calculations with it (finding vertices for example.) {{{FeynmanGauge}}} is set to {{{False}}} by default. The NLO counterterms have been computed and can be found in the 27 [/attachment/wiki/StandardModel/SMQCD.nlo SMQCD.nlo]. They can be exported in the UFO format to Madgraph5/aMCatNLO. 24 28 === Examples === 25 29 * [/attachment/wiki/StandardModel/SM.nb SM.nb]: This is an example Mathematica® notebook that loads SM.fr and calculates Feynman rules. … … 27 31 === Validation === 28 32 The SM implementation was extensively tested on various 2-to-2 processes. A selection is shown in [/attachment/wiki/StandardModel/XS1.jpg this table]. (Note that the discrepancy with MG stock simply comes from the fact that MG stock has the 4 higgs vertex not implemented). 33 The counterterms analytic expressions have been checked with the literature and the UFO compared with the built in version of SM in Madgraph5/aMCatNLO. 29 34 30 35 === Interfaces ===
