Standard convolution description of deuteron tensor spin structure

Abstract

Spin-1 hadrons have additional structure functions not present for spin 1/2 hadrons. These could probe novel aspects of hadron structure and QCD dynamics. For the deuteron, the tensor structure function b1b_1 inherently mixes quark and nuclear degrees of freedom. These proceedings discuss two standard convolution models applied to calculations of the deuteron b1b_1 structure functions. We find large differences with the existing HERMES data and other convolution model calculations. This leaves room for non-standard contributions to b1b_1 in the deuteron. We also discuss the influence of higher twist nuclear effects in the model calculations and data extraction at kinematics covered in HERMES and Jefferson Lab.
