“Asymptotic KNO scaling for Mueller's dipole in the double-logarithm limit”


We analyze Mueller's QCD dipole wave function evolution in the double logarithm (DLA) limit. Using complex analytic methods, we show that the distribution of dipoles in the wave function asymptotically satisfies the Koba-Nielsen-Olesen (KNO) scaling with a novel scaling function f(z). The behavior of the scaling function in the DLA limit is qualitatively different from the expected scaling e^{-z} in the diffusion limit: at large z the f(z) decays as ze^{-z/0.3917} , while at small z the speed of growth is log-normal-like . The bulk and asymptotic results are shown to be in good agreement with the measured hadronic multiplicities in DIS, as reported by the H1 collaboration at HERA.


The seminar will be in a hybrid mode, local people are invited to meet in the seminar room D-2-02.
