Abstract:
Nonlocal gauge theories including gravity are considered. It is shown that the
introduction of the additional nonlocal interaction makes $\gamma_5$-anomalous theories
meaningfull. The introduction of such interaction leads to macrocausal unitaire theory,
which describes the interaction of massive vector fields with fermion fields. It is shown
that nonlocal gauge theories with nonlocal scale $\Lambda_{n1}\lesssim (1\div 10)$ TeV can solve the gauge
hierarchy problem. An example of nonlinear grand unification gauge model in which
topologically nontrivial finite energy monopole solutions are absent is found.
