    3333
     34 * [http://feynrules.irmp.ucl.ac.be/wiki/typeIseesaw/heavyN.fr heavyN.fr]:  Main model file.
     35 * [http://feynrules.irmp.ucl.ac.be/wiki/typeIseesaw/heavyN.nb heavyN.nb]:  Mathematica notebook file that loads FR and model, allows user to run quick sanity checks (optional), and outputs UFO file.
     36 * [http://feynrules.irmp.ucl.ac.be/wiki/typeIseesaw/Seesaw_TypeI.tgz Seesaw_TypeI.tgz]: Standalone package containing heavyN.fr, heavyN.nb, massless.rst (default FR file), diagonalCKM.rst (default FR file), and sm.fr (default FR file). To unpack, use the command:
     37~/home/$ tar -zxvf Seesaw_TypeI.tgz
     38 * [http://feynrules.irmp.ucl.ac.be/wiki/typeIseesaw/Seesaw_TypeI_withUFO.tgz Seesaw_TypeI_withUFO.tgz]: Same as Seesaw_TypeI.tgz but with UFO folder generated using restrictions massless.rst (only massive fermions are top quark and Majorana neutrino) and diagonalCKM.rst (CKM matrix set to unity).
     39 * [http://feynrules.irmp.ucl.ac.be/wiki/typeIseesaw/Seesaw_TypeI_UFO.tgz Seesaw_TypeI_UFO.tgz]: Standalone UFO folder as packaged in Seesaw_TypeI_withUFO.tgz.

     41Notes:
     42 * The model contains five free parameters in addition to SM parameters: heavy neutrino mass mN, heavy neutrino with WN, and mixing matrix elements VeN, VmuN, and VtaN that parameterize the mixing between lepton flavor eigenstates (\nu_e, \nu_mu, \nu_tau) and heavy mass eigenstate N. '''Note''': VlN are restricted to be real in the model file.

    3444=== Validation ===
     45This model file was validated using FeynRules v2.0.6 and MG5_aMC@NLO (MG5) v2.1.0. The results are reported in Ref. [#Alva 2].
