Аннотация:
We present a new class of evolution equations that govern the
high-energy behavior of power-suppressed scattering amplitudes. The
equations can be viewed as a renormalization group flow with respect
to the relevant effective field theory cutoff. A distinct feature of
the method is in the use of a multidimensional cutoff to separate the
relevant scales in problems characterized by a complex factorization
structure. By adjusting the renormalization group variables to the
geometry of the effective theory modes, our method naturally extends
to a broad spectrum of physical problems that include massive,
massless, small, and wide-angle scattering. We present applications to
the benchmark processes of electron-positron forward annihilation and
light-quark-mediated Higgs boson production and decays.
