K over K multiplicity ratio for kaons produced in DIS with a large fraction of the virtual-photon energy
R. Akhunzyanov, M. G. Alexeev, G. D. Alexeev +207
The K over K multiplicity ratio is measured in deep-inelastic scattering, for the first time for kaons carrying a large fraction of the virtual-photon energy. The d…
Interplay among transversity induced asymmetries in hadron leptoproduction
Compass Collaboration, C. Adolph, R. Akhunzyanov +206
In the fragmentation of a transversely polarized quark several left-right asymmetries are possible for the hadrons in the jet. When only one unpolarized hadron is selected, it exhi…
