Shadowing in deuterium.

Inhomogeneous shadowing effects on J/psi production in dA collisions.

We study the effect of spatially homogeneous and inhomogeneous shadowing on J/psi production in deuterium-nucleus collisions. We discuss how the shadowing and its spatial dependence can be measured by comparing central and peripheral dA collisions. These event classes may be selected by using gray protons from heavy ion breakup and events where the proton or neutron in the deuterium does not in...

Open and Hidden Charm Production in dA Collisions at RHIC and LHC

We discuss aspects of open and hidden charm production in deuterium-nucleus collisions at RHIC and LHC energies. We describe calculations of the total cc cross section and the charm quark transverse momentum distributions. We next explain how shadowing and moderate nuclear absorption can explain the PHENIX J/ψ dAu/pp ratios and predict the combined effect of shadowing and absorption in 6.2 TeV ...

Neutron Structure Functions From Nuclear Data

The spin-averaged structure function of the neutron, F n 2 , is extracted from recent deuteron data, taking into account the small but significant corrections from nuclear effects in the deuteron. At small x, the F D 2 /F p 2 ratio measured by the New Muon and Fermilab E665 Collaborations is interpreted to suggest a small amount of shadowing in deuterium, which acts to enhance F n 2 for x < ∼ 0...

Global Study of Nuclear Structure Functions

We present the results of a phenomenological study of unpolarized nuclear structure functions for a wide kinematical region of x and Q2. As a basis of our phenomenology we develop a model which takes into account a number of different nuclear effects including nuclear shadowing, Fermi motion and nuclear binding, nuclear pions and off-shell correction to bound nucleon structure functions. Within...
