The LHC experiment at CERN has established a golden era for precision measurements in particle physics, opening the possibility to detect deviations from the Standard Model predictions and constrain the new physics, up to the multi-TeV scales. In this work, a procedure is described to use this data to obtain bounds on a higher-dimensional operator, that describes new gluon self-interactions than the Standard Model ones, in an Effective Field Theory framework. In Chapter one, the Standard Model is breefly rehearsed: in Chapter two, the LHC main features are overviewed. In Chapter three, the Effective Field Theory approach is explained, with particular attention to the operator we are interested in this work; the previous works about it are summarised. Finally, in Chapter four, the possibility to constrain it by considering its interference with the Standard Model is detailedly explained, and some results from simulations are analysed.
