Five-Loop Static Contribution to the Gravitational Interaction Potential of Two Point Masses [arXiv:1902.11180; DESY-19-029; DO-TH-19/01]   We compute the static contribution to the gravitational interaction potential of two point masses in the velocity-independent five-loop (and 5th post-Newtonian) approximation to the harmonic coordinates effective action in a direct calculation. The computation is performed using effective field methods based on Feynman diagrams in momentum-space in $d = 3 - 2\varepsilon$ space dimensions.

In combination with a conventional fixed-order event generator, HEJ 2 can be used to obtain greatly improved predictions for a number of phenomenologically important processes by adding all-order logarithmic corrections in $\hat{s}/p_\perp^2$.

We focus on the two-point correlation functions of probe charges and the field-strength operator, finding excellent quantitative agreement with the functional form and the continuously varying critical indices predicted by conformal field theory..

The measurements are based on data collected by the CMS experiment at the LHC.

These combinations are performed per centre-of-mass energy and for each production mode: $t$-channel, $tW$, and $s$-channel.

Measurements of the inclusive deep inelastic cross sections in neutral and charged current $ep$ scattering were considered.

Specifically, we have obtained the respective non-singlet quark–quark anomalous dimensions at N=2 and N=3 to the fifth order in the strong coupling αs .

The method is based on the measurement of dilepton production from the $\gamma p\rightarrow\ell^+\ell^-+X$ reaction in proton--lead collisions.

The inclusive cross section is measured to be $\sigma_{\text{tot}}($pp$\to$WZ$) =$ 48.09 $^{+1.00}_{-0.96}$ (stat) $^{+0.44}_{-0.37}$ (theo) $^{+2.39}_{-2.17}$ (syst) $\pm$ 1.39 (lumi) pb, resulting in a total uncertainty of $-$2.78/$+$2.98 pb.
