Sudakov logs and power corrections for selected event shapes

open access: yes, 2004
I summarize the results of recent studies analyzing perturbative and nonperturbative effects of soft gluon radiation on the distributions of the C-parameter and of the class of angularities, by means of dressed gluon exponentiation.Comment: Talk given at

DVCS via color dipoles: Nonperturbative effects

open access: yes, 2008
We study the DVCS amplitude within the color dipole approach. The light-cone wave function of a real photon is evaluated in the instanton vacuum model. Our parameter free calculations are able to describe H1 data, both the absolute values and the $t$-dependences, at medium-high values of $Q^{2}$.
