The exclusive η and π^(0)electroproduction is studied in the handbag approach based on the generalized parton distributions(GPDs)factorization.Predictions of π^(0)and η mesons are calculated for future electron-io...

Using transverse spin to explore nucleon structure is a focus of moderate and high energy nuclear physics for the moment. We measure the neutron single spin asymmetry in the semi-inclusive deep-inelastic reaction with...

We analyze the left-right asymmetry in the semi-inclusive deep inelastic scattering (SIDIS) process using a method where no weighting function are used. Considering all flavor of quarks, we reanalyze the π±product...

The exponential dichotomy and the theory of transversality are used to give the condition and its geometric significance for the persistence of a singular orbit with higher degeneracy under small autonomous perturbati...
