Higher Twist contributions to the Structure Functions F_2(x,Q^2) and
g_2(x,Q^2)    [PDF]

Johannes Blümlein, Helmut Böttcher

We report on recent results on higher twist contributions to the unpolarized structure functions $F_2^{p,d}(x,Q^2)$ at N$^3$LO in the large $x$ region and constraints on the twist--3 contribution to polarized structure function $g_2(x,Q^2)$.
