Sven Moch: Physics at the LHC at the precision frontier

We review the current state of precision predictions for the LHC covering the aspects of perturbative corrections at higher orders to hard scattering processes, the parton distribution functions as non-perturbative input at hadron colliders and our knowledge on fundamental parameters of the Standard Model such as the strong coupling constant alpha_s and the quark masses m_c, m_b and m_t.
We illustrate how the precision of available experimental data challenges current theoretical predictions and we outline areas for future improvements.
