Nucleon spin structure at low momentum transfers
Roman Pasechnik, Jacques Soffer, Oleg Teryaev
The generalized Gerasimov-Drell-Hearn (GDH) sum rule is known to be very sensitive to QCD radiative and power corrections. We improve the previously developed QCD-inspired model fo…
Model-independent constraints on spin observables
Jean-Marc Richard, Xavier Artru, Mokhtar Elchikh +2
We discuss model-independent constraints on spin observables in exclusive and inclusive reactions, with special attention to the case of photoproduction.
The relevance of positivity in spin physics
J. Soffer, X. Artru, M. Elchikh +2
Positivity reduces substantially the allowed domain for spin observables. We briefly recall some methods used to determine these domains and give some typical examples for exclusiv…
Constraints on spin observables
Jean-Marc Richard, Xavier Artru, Mokhtar Elchikh +2
Positivity constrains the allowed domain for sets of spin observables in exclusive or inclusive reactions. Examples are given for strangeness-echange reactions and photoproduction.
Spin observables and spin structure functions: inequalities and dynamics
Xavier Artru, Mokhtar Elchikh, Jean-Marc Richard +2
Model-independent identities and inequalities relating the various spin observables of a reaction are reviewed in a unified formalism, together with their implications for dynamica…
QCD radiative and power corrections and Generalized GDH sum rules
Jacques Soffer, Oleg Teryaev
We extend the earlier suggested QCD-motivated model for the -dependence of the generalized Gerasimov-Drell-Hearn (GDH) sum rule which assumes the smooth dependence of the stru…
