Polarized Structure Functions with Neutrino Beams
نویسنده
چکیده
Physics with neutrino beams has played a crucial role in establishing the standard model and its structure, specifically in leading to the discovery of weak neutral currents and of their properties. Currently, while the physics of neutrinos gives us the first evidence of physics beyond the standard model, the use of neutrinos as probes appears to be the only way of accessing subtle details of the structure of the standard model, on the one hand, and of the nucleon, on the other hand. This is due to the obvious fact that weak currents, unlike the electromagnetic current, couple nontrivially to spin and flavour. Current data offer tantalizing evidence of this situation: neutrino scattering data from the NuTeV collaboration provide evidence for unexpected

Hadron Physics at a Neutrino Factory
We review the way intense neutrino beams at the front–end of a muon storage ring can be used to probe the structure of hadrons. Specifically, we discuss how the polarized and unpolarized flavor structure of the nucleon can be disentangled in inclusive deep-inelastic scattering, and how less inclusive measurements can shed light on various aspects of hadron structure such as fragmentation functi...

We review the physics potential for experiments with intense neutrino beams at the front–end of a muon storage ring, stressing the way the spin and flavour structure of neutrino interactions with matter can be used to shed light on the structure of the strong and electroweak interactions. Specifically, we discuss precision tests of the standard model, studies of polarized and unpolarized struct...

For neutrino scattering from polarized electron, the weak interaction term in the cross section is significantly suppressed by the polarized term. The magnetic moment term does not receive any correction from the electron polarization. Hence, the study of the magnetic moment of neutrinos through scattering from the polarized electron leads to a stronger bound on the neutrino magnetic moment com...
متن کاملStructure functions of the nucleon and nuclei in neutrino reactions
Determination of parton distribution functions in nuclei is important for calculating nuclear corrections in oscillation experiments, from which detailed information should be extracted on neutrino properties. First, nuclear parton distributions are discussed for explaining high-energy nuclear reaction data. Possible nuclear modification is explained for valence-quark and antiquark distribution...

The studies of neutrino interactions with nuclei has been an actively developing field both experimentally and theoreticaly [1,2]. Nuclear physics studies with (anti)neutrino beams are relevant in two different contexts. First, it must be noted that neutrino collision experiments usually use heavy-nucleus targets. For this reason a good understanding of “standard” nuclear effects is necessary f...
