Ultra - High Energy Neutrino - Nucleon Scattering and Parton Distributions at Small x
نویسندگان
چکیده
The cross section for ultra-high energy neutrino-nucleon scattering is very sensitive to the parton distributions at very small values of Bjorken x (x ≤ 10−4). We numerically investigate the effects of modifying the behavior of the gluon distribution function at very small x in the DGLAP evolution equation. We then use the Color Glass Condensate formalism to calculate the neutrino-nucleon cross section at ultrahigh energies and compare the result with those based on modification of DGLAP evolution equation.

Dynamical QCD Predictions for Ultrahigh Energy Neutrino Cross Sections
Neutrino-nucleon total cross sections for neutrino energies up to ultrahigh energies (UHE), Eν = 10 12 GeV, are evaluated within the framework of the dynamical (radiative) parton model. The expected uncertainties of these predictions do not exceed the level of about 20 % at the highest energies where contributions of parton distributions in the yet unmeasured region around x ≃ 10 to 10 are non-...
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...
متن کاملDynamical Parton Distributions Revisited
Dynamical parton densities, generated radiatively from valence–like inputs at some low resolution scale, are confronted with recent small–x data on deep inelastic and other hard scattering processes. It is shown that within theoretical uncertainties our previous (1994) dynamical/radiative parton distributions are compatible with most recent data and still applicable within the restricted accura...
متن کاملEvidence for Charge Symmetry Violation in Parton Distributions
By comparing structure functions measured in neutrino and charged lepton deep inelastic scattering, one can test the validity of parton charge symmetry. New experiments allow us to make such tests, which set rather tight upper limits on parton charge symmetry violation [CSV] for intermediate Bjorken x, but which appear to show sizable CSV effects at small x. We show that neither nuclear shadowi...
متن کاملUltra-high energy neutrino-nucleon cross section and radiative corrections
A cubic kilometer scale experiment has been proposed to detect cosmic neutrinos of energy from tens of GeV up to the highest energies observed for cosmic rays, ∼ 10 eV, or possibly even beyond. Detection efficiencies depend crucially on the neutrino-nucleon cross section at these energies at which radiative corrections beyond the lowest order approximation could become non-negligible. The diffe...
