Summary, in English

The amplitude for scalar Higgs boson production in the fusion of two off-shell gluons is calculated including finite (not infinite) masses of quarks in the triangle loop. In comparison to the effective Lagrangian approach, we have found a new term in the amplitude. The matrix element found can be used in the k-factorization approach to the Higgs boson production. The results are compared with the calculations for on-shell gluons. Small deviations from the cos2φ-dependence are predicted. The off-shell effects found are practically negligible.
