The model contains baryon-(and lepton)-number-violating (BNV) four-fermion interactions: tbμc, tbue, tτdu. They for instance lead to the t→b̅c̅μ⁺ decay and ub→t̅e⁺ single top production in association with a single lepton. Please refer to: [https://arxiv.org/abs/1107.3805] Contact person: Gauthier Durieux
