  We consider a Euclidean extension of the wedge form of Hamiltonian dynamics,
which explicitly accounts for the strong localization of the first interaction
in nuclear collisions. A new principle of the analytic continuation via the
tetrad vector is introduced. We discover the existence of self-dual solutions
with short life-times (ephemerons) and conjecture that these vacuum
fluctuations can lower the Euclidean action of the system of the colliding
nuclei, thus enforcing a breakdown of the nuclei coherence. We suggest that the
ephemerons can be identified with the gluons-partons, which are resolved in
high-energy nuclear collisions.
