Perturbative Effects in the Form Factor γγ^*\to πand Extraction of the Pion Wave Function from CLEO Data

Alexander Schmedding, Oleg Yakovlev

We study the pion form factor F^{πγγ^*}(Q^2) in the light-cone sum rule approach, accounting for radiative corrections and higher twist effects. Comparing the results to the CLEO e…

On the resummation of double logarithms in the process Higgs --> two photons

M. I. Kotsky, O. I. Yakovlev

The decay of the Higgs boson into two photons is discussed. Using Sudakov technicue, we study a new type of double logarithms in the case of the light quark loop. First, we examine…

QCD Sum Rules for Heavy Baryons at Next-to-Leading Order in alpha_s

S. Groote, J. G. Körner, O. I. Yakovlev

We derive QCD sum rules for heavy baryons at leading order in and at next-to-leading order in . The calculation involves the evaluation of four different perturbative…
