 The model contains baryon-(and lepton)-number-violating (BNV) four-fermion interactions like tbμc, tbue, tτdu. These interactions for instance lead to the t→b̅c̅μ⁺ decay and ub→t̅e⁺ single top production in association with a single lepton.

 To overcome !MadGraph limitations, the model introduces a very heavy fictitious mediator {{{X}}} which effectively generates the required four-fermion interactions. Its mass {{{MX}}} is set by default to 1 PeV and should be kept much higher than the energy scale of the considered process, so that computation do not depend on its exact value.
 
-The BNV decay width of the top quark as well as the {{{u d > t~ ta+}}} matrix element computed by !MadGraph in {{{standalone_cpp}}} mode (for various combinations of {{{aaa3x1}}}, {{{bbb3x1}}}, {{{ccc1x3}}}, {{{ddd1x3}}}, {{{aaaprime3x3}}}, {{{bbbprime3x3}}}, {{{cccprime1x1}}}, {{{dddprime1x1}}} and at various phase-space point) have been validated against analytical computations.
