Anomalous Sudakov Form Factors
, 909
"... While radiative corrections of infrared origin normally depress high energy amplitudes (Sudakov form factors), we find that in some cases resummation of leading effects produces exponentials with positive exponents, giving rise to amplitudes that grow indefinitely with energy. The effect happens in ..."

Sudakov Form Factors in Leptoproduction of Vector Mesons
, 1997
"... It is shown that Sudakov form factors for a colour dipole in a QCDinspired model of leptoproduction of vector mesons reduce the value of the cross section of the process by an order of magnitude. They suppress the large size quarkantiquark pairs and unequal sharing of energy among the components of ..."

Mass scale effects for the Sudakov form factors in theories with the broken gauge symmetry
, 2002
"... The offshell and the onshell Sudakov form factors in theories with broken gauge symmetry are calculated in the doublelogarithmic approximation. We have used different infrared cutoffs, i.e. different mass scales, for virtual photons and weak gauge bosons. ..."

Electroweak Sudakov form factors and nonfactorizable soft QED effects at NLC energies
, 1999
"... We study the leading log infrared behavior of electroweak corrections at TeV scale energies, that will be reached by next generation of linear colliders (NLC). We show that, contrary to what happens at typical LEP energies, it is not anymore possible to disentangle “pure electroweak ” from “photonic ..."
Abstract
 Add to MetaCart
“photonic ” corrections. This means that soft QED effects do not factorize and therefore cannot be treated in the usual “naive ” way they were accounted for in the LEPera. The nonfactorizable effects come up first at the two loop LL level, that we calculate explicitly for a fermion source that is neutral
THE PION FORM FACTOR: SUDAKOV SUPPRESSIONS AND INTRINSIC TRANSVERSE MOMENTUM
, 1993
"... It is demonstrated that any attempt to calculate the perturbative QCD contribution to the pion form factor requires the inclusion of intrinsic transverse momentum besides Sudakov form factors. For momentum transfers of the order of a few GeV the intrinsic transverse momentum leads to a substantial s ..."
