Effective 4 top operators :

Implemented operators are

 $\mathcal{O}_{R} = \!\left( \bar{t}_R \gamma^\mu t_R \right) \!\left( \bar{t}_R \gamma_\mu t_R \right)$ 

 $\mathcal{O}_{L}^{(1)} = \!\left( \bar{Q}_L \gamma^\mu Q_L \right) \!\left( \bar{Q}_L \gamma_\mu Q_L \right)$ 

 $\mathcal{O}_{L}^{(8)} = \!\left( \bar{Q}_L \gamma^\mu T^A Q_L \right) \!\left( \bar{Q}_L \gamma_\mu T^A Q_L \right)$ 

 $\mathcal{O}_{B}^{(1)} = \!\left( \bar{Q}_L \gamma_\mu Q_L \right) \!\left( \bar{t}_R \gamma_\mu t_R \right)$ 

 $\mathcal{O}_{B}^{(8)} = \!\left( \bar{Q}_L \gamma_\mu T^A Q_L \right) \!\left( \bar{t}_R \gamma_\mu T^A t_R \right)$ 

There coefficients are respectively named CRL2, C1LL2,C8LL2, C1BL2, C8BL2, they are in TeV^-2 (they include 1/Lambda²) and they have a coupling order NP=2.
