Measurement of azimuthal asymmetries associated with deeply virtual Compton scattering on a longitudinally polarized deuterium target
The HERMES Collaboration, A. Airapetian, N. Akopov +144
Azimuthal asymmetries in exclusive electroproduction of a real photon from a longitudinally polarized deuterium target are measured with respect to target polarization alone and wi…
Partially Isometric Immersions and Free Maps
Giuseppina D'Ambra, Roberto De Leo, Andrea Loi
In this paper we investigate the existence of ``partially'' isometric immersions. These are maps f:M->R^q which, for a given Riemannian manifold M, are isometries on some sub-bundl…
Solvability of the cohomological equation for regular vector fields on the plane
Roberto De Leo
We consider planar vector field without zeroes X and study the image of the associated Lie derivative operator LX acting on the space of smooth functions. We show that the cokernel…
Effects of transversity in deep-inelastic scattering by polarized protons
HERMES collaboration, A. Airapetian, N. Akopov +142
Single-spin asymmetries for pions and charged kaons are measured in semi-inclusive deep-inelastic scattering of positrons and electrons off a transversely nuclear-polarized hydroge…
Exclusive Leptoproduction of Real Photons on a Longitudinally Polarised Hydrogen Target
The HERMES Collaboration, A. Airapetian, N. Akopov +147
Polarisation asymmetries are measured for the hard exclusive leptoproduction of real photons from a longitudinally polarised hydrogen target. These asymmetries arise from the deepl…
Leading-Order Determination of the Gluon Polarization from high- Hadron Electroproduction
The HERMES Collaboration, A. Airapetian
Longitudinal double-spin asymmetries of charged hadrons with high transverse momentum have been measured in electroproduction using the \hermes\ detector at \hera. Processes…
Global Solvability in Functional Spaces for Smooth Nonsingular Vector Fields in the Plane
Roberto De Leo, Todor Gramchev, Alexandre Kirilov
We address some global solvability issues for classes of smooth nonsingular vector fields in the plane related to cohomological equations in geometry and dynamical syste…
