In the framework of model motivated by perturbative calculations in QCD we estimate the differential and total cross sections for both the photoproduction of vector D *-mesons and their yield in deep inelastic scattering at the HERA collider. The offered model allows us to take into account higher twists over the transverse momentum of meson at p T ∼ m c and correctly to approach the dominance ...

The quantum properties of solitons at one loop can be related to phase shifts of waves on the soliton background. These can be combined with heat kernel methods to calculate various parameters. The vacuum energy of a CP (1) soliton in 2 + 1 dimensions is calculated as an example. Pacs numbers: 11.10.Lm Typeset using REVTEX 1
