Description

We evaluate the gluon and charm parton distribution functions (PDFs) of the deuteron using light-front quantization together with the impulse approximation. We use a nuclear wave function obtained by solving the nonrelativistic Schrödinger equation with the realistic Argonne v18 nuclear force; it is then convoluted with the proton PDF. The resulting gluon distribution in the deuteron (per nucleon) is smaller than that of the proton by a few percent close x = 0.4, whereas it is enhanced at x larger than 0.6. We discuss the applicability of our computation and comment on how to extend it to x as large as two. We also analyze the charm distribution of the deuteron within the same approach by considering perturbatively and non-perturbatively (intrinsic) generated charm inside the deuteron. In particular, we note that the intrinsic charm content in the deuteron may be enhanced for 6-quark configurations.
