  Horndeski/Galileons may be considered as a proper generalization of General
Relativity in high energy regime. Thus one may search for manifestation of
Galileons interaction in collision experiments. In this paper we give arguments
supporting this thesis. Galileon scalar field do not interact with matter via
Standard Model interactions, we discuss a mechanism that allows Galileons to
have influence on particle collisions. We give reasons to narrow the whole
class of Horndeski/Galileons models to one particular term - John term from Fab
Four subclass - for this particular issue. We were able to establish the
constraint on the model coupling constant.
