Nuclear Effects in Neutrino Structure Functions
We discuss calculation of nuclear corrections to the structure functions for the deepinelastic scattering of muon and (anti)neutrino. Our approach includes a QCD description of the nucleon structure functions as well as the treatment of Fermi motion and nuclear binding, off-shell correction to bound nucleon structure functions, nuclear pion excess and nuclear shadowing. We emphasize the depende...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Nuclear effects on the spin-dependent structure functions
We address the question how the spin-dependent nucleon structure function g1 ( x,Q ) gets modified when the nucleon is bound inside a nucleus. We analyze the influence of nuclear interactions using the ∆−π model, known to describe well the unpolarized effect, and the free polarized parton distributions. The results for the neutron in He and proton in H, Li and F are presented, showing significa...
متن کاملNuclear Effects on the Extraction of Neutron Structure Functions
Nuclear effects in light nuclei due to the presence of spin-one isosinglet 6-quark clusters are investigated. The quark distributions of 6-quark clusters are obtained by using a perturbative QCD (pQCD) based framework, which allows us to get a good description of the ratio of the deuteron structure function to the free nucleon structure function. Nuclear effects on the extraction of the neutron...
متن کاملRescaling of Nuclear Structure Functions
It is shown that nucleonic structure functions are x− and Q 2 −rescaled in nuclei. The x−rescaling accounts for nuclear effects in the case of exact scaling, while the Q 2 −rescaling is responsible for a corresponding modification of quantum corrections. This result is obtained in the leading order for all flavour combinations and connects the two known models for the EMC-effect. Electroproduct...
