Query: High-Energy Limit of QCD beyond Sudakov Approximation   We study the high-energy limit of the scattering amplitudes suppressed by the
leading power of the quark mass in perturbative quantum chromodynamics. We
prove the factorization and perform all-order resummation of the
double-logarithmic radiative corrections which determine the asymptotic
behavior of the amplitudes. In contrast to the Sudakov logarithms, the
mass-suppressed double-logarithmic corrections are induced by soft quark
exchange. The structure of the corrections and the asymptotic behavior of the
amplitudes in this case crucially depend on the color flow in a given process
and are determined by the eikonal color charge nonconservation. We present
explicit results for the Higgs boson production in gluon fusion mediated by a
light-quark loop and for the leading power-suppressed contributions to the
quark form factors, which reveal "magical" universality. Nontrivial relations
between the asymptotic behavior of different amplitudes and the amplitudes in
different gauge theories are found.
