This report summarizes the proceedings of the 2014 Mainz Institute for Theoretical Physics (MITP) scientific program on High precision fundamental constants at the TeV scale. The two outstanding parameters in the Standard Model dealt with during the
MITP scientific program are the strong coupling constant $alpha_s$ and the top-quark mass $m_t$. Lacking knowledge on the value of those fundamental constants is often the limiting factor in the accuracy of theoretical predictions. The current status on $alpha_s$ and $m_t$ has been reviewed and directions for future research have been identified.
We present a program to calculate the total cross section for top-quark pair production in hadronic collisions. The program takes into account recent theoretical developments such as approximate next-to-next-to-leading order perturbative QCD correcti
ons and it allows for studies of the theoretical uncertainty by separate variations of the factorization and renormalization scales. In addition it offers the possibility to obtain the cross section as a function of the running top-quark mass. The program can also be applied to a hypothetical fourth quark family provided the QCD couplings are standard.
We summarize recent experimental and theoretical results, which were reported in the working group on Structure Functions and Low-x at the DIS 2007 workshop.
