Аннотация:We are considering a possibility for detecting nonperturbative effect in process of top
pair production in association with a high pT photon. Starting from previous results on
two solutions for a spontaneous generation of an effective interaction of a top pair with
a pair of electroweak bosons, we show that a solution with effective cutoff Λ≃100 TeV
is already contradicting to the existing data, while the other one with Λ≃10^16 TeV
(just the Planck scale) could be reconciled with data and give predictions for process
p + p → ttγ + X, which could be effectively checked at the LHC with √s = 13 TeV.
The confirmation of the predictions would mean a strong support for the existence of
nonperturbative effects in the electroweak interaction.
