v28 v29 41 41 \end{eqnarray} 42 42 }}} 43 Neutrino masses (mNk) and mixing parameters (Vlk) between heavy mass eigenstate and (active) flavor eigenstates are taken to be independent, phenomenological parameters. Mixing parameters (VeN, VmuN, VtaN) are taken to be real (no CP Violation). This allows for maximum flexibility and model independence when calculating rates. Therefore, some care by the user is required.43 Neutrino masses (mNk) and mixing parameters (Vlk) between heavy mass eigenstate and (active) flavor eigenstates are taken to be independent, phenomenological parameters. This allows for maximum flexibility and model independence when calculating rates. Therefore, some care is required by the user. 44 44 The lepton number and flavorviolating interactions of the Lagrangian allow for modeling of the Type I, Inverse, and Linear seesaw mechanisms at both lepton, hadron, and leptohadron colliders. 45 45 … … 47 47 The above Lagrangian with Goldstone boson couplings and in the Feynman Gauge was implemented into FeynRules 2.3.10. QCD renormalization and R2 rational counter terms were determined using NLOCT 1.02 and FeynArts 3.8. Feynman rules were collected into a single UFO, available below. 48 48 In the UFO file, five massless quarks are assumed as are zero offdiagonal CKM matrix entries. 49 For additional details, see [ [#Degrande 2] ] and references within.49 For additional details, see [ [#Degrande 2] ] and references therein. 50 50 These additions permit treelevel calculations at LO and NLO in QCD and loopinduced calculations at LO in QCD using MadGraph_aMC@NLO. 51 51 … … 64 64 65 65 66 == = Notes ===66 == Notes == 67 67 * To download any of the packages and unpack via the terminal, use the commands: 68 68 … … 78 78 * Three masses: mN1, mN2, mN3. Defaults are 300 GeV, 500 GeV, and 1 TeV, respectively. 79 79 * Three widths: WN1, WN2, WN3. Defaults are 0.303 GeV, 1.50 GeV, and 12.3 GeV, respectively. 80 * Nine mixing parameters: V''lk'' for ''l'' = ''e, mu, tau'' and ''k'' = 1,2,3. Default values are V''lk'' = Identity(3x3), i.e., Ve1 = Vmu2 = Vta3 = 1 and all others zero.80 * Nine real (no CP violation) mixing parameters: V''lk'' for ''l'' = ''e, mu, tau'' and ''k'' = 1,2,3. Default values are V''lk'' = Identity(3x3), i.e., Ve1 = Vmu2 = Vta3 = 1 and all others zero. 81 81 * '''Note''': VlN are restricted to be real in the model file. 82 82 * '''Note''': Default parameters are set so "outofthebox" checks can be made with [ [#Alva 1] ] and [ [#Degrande 2] ].
