| 11 | === Description of the model & reference === |
| 12 | |
| 13 | The top effective theory model contains all the dimension-six operators affecting top pair production, single top pair production and top decay by interfering with the SM amplitudes. |
| 14 | |
| 15 | The four-fermion operators are implemented through the exchange of heavy bosons. |
