The present work proposes a Born–Infeld contribution to the 
extension of the Standard Model, where it is introduced associated to the X17 neutral boson. The decay width of the decay into 3X and 3
processes are computed, based on NA64 and ATLAS experiments data.
In honor of the 60th birthday of Prof. Daniel Heber Theodoro Franco.
