Higher Twist Contributions to the Structure Functions F_2^p(x,Q^2) and F_2^d(x,Q^2) at Large x and Higher Orders

Johannes Blümlein, Helmut Böttcher

The higher twist contributions to the deeply inelastic structure functions $F_2^p(x,Q^2)$ and $F_2^d(x,Q^2)$ for larger values of the Bjorken variable $x$ are extracted extrapo…
