- * The flagship {{{HeavyN}}} UFO model contains 15 free parameters:
-  * Three masses: mN1, mN2, mN3. Defaults are 300 GeV, 500 GeV, and 1 TeV, respectively.
-  * Three widths: WN1, WN2, WN3. Defaults are 0.303 GeV, 1.50 GeV, and 12.3 GeV, respectively.
-  * 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.
-  * '''Note''': VlN are restricted to be real in the model file.
-  * '''Note''': Default parameters are set so "out-of-the-box" checks can be made with [ [#Alva 1] ] and [ [#Degrande 2] ].
-
-* For the Majorana file, particle identification (PID) codes for N1,...,N3, follow standard HEP MCPID codes: 9900012, 9900014, 9900016
-
-* For the Dirac file, to avoid conflict with Pythia8, where the above PIDs are reserved for Majorana fields, the nonstandard HEP MCPID codes for N1,...,N3 are:9990012, 9990014, 9990016
-
-* For the vSMEFT file, 10 additional model parameters are introduced: 
-  * One EFT cutoff scale {{{Lambda}}} in units of GeV.
-  * Nine Wilson coefficients coupling {{{N_k}}} to {{{l}}}: {{{CeN1, CeN2, CeN3, CmuN1, CmuN2, CmuN3, CtaN1, CtaN2, CtaN3}}}
-  * '''Note''': Default parameters are set such that {{{Lambda=1000}}} (GeV), {{{CeN1=CmuN2=CtaN3=1}}}, and all other coefficients are zero
-
+ * In addition to SM parameters, the flagship {{{SM_ZeeBabu_NLO}}} UFO model contains two particles and 19 free parameters:
+  * {{{k--}}} (PID=61) and {{{h-}}} (PID=38) with antiparticles {{{k++}}} (PID=-61) and {{{h+}}} (PID=-38)
+  * Two masses: {{{mhZB}}}, {{{mkZB}}}. Default values are 300 GeV and 500 GeV, respectively.
+  * Two widths: {{{whZB}}}, {{{wkZB}}}. Default values are 1 GeV.
+  * One dimensionful parameter: {{{muZB}}}. Default value is 1 TeV.
+  * Five real scalar couplings: {{{lamhZB, lamkZB, lamhZBkZB, lamhZBH, lamkZBH}}}. Default values are 1.
+  * Six real Yukawa couplings for l-v-h: {{{gee,  gemu,  getau, gmumu, gmutau, gtautau}}}. Default values are 1.
+  * Three real Yukawa couplings for l-l-k: {{{femu, fetau, fmutau}}}. Default values are 1.
