Higher Twist Contributions to Deep-Inelastic Structure Functions

Johannes Blümlein, Helmut Böttcher

We report on a recent extraction of the higher twist contributions to the deep inelastic structure functions $F_{2}^{e p, e d} (x, Q^{2})$ in the large $x$ region. It is shown that the size…

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…

Two--Loop Massive Operator Matrix Elements for Unpolarized Heavy Flavor Production to $O(ε)

Isabella Bierenbaum, Johannes Blümlein, Sebastian Klein +1

We calculate the $O (α_{s}^{2})$ massive operator matrix elements for the twist--2 operators, which contribute to the heavy flavor Wilson coefficients in unpolarized deeply inelastic sc…

Status of Deeply Inelastic Parton Distributions

Johannes Blümlein

A brief review on the status of unpolarized parton densities and the determination of the QCD scale $Λ_{QCD}$ from deep-inelastic scattering data is presented.
