FiveLoop Static Contribution to the Gravitational Interaction Potential of Two Point Masses
[arXiv:1902.11180; DESY19029; DOTH19/01]
We compute the static contribution to the gravitational interaction potential of two point masses in the velocityindependent fiveloop (and 5th postNewtonian) approximation to the harmonic coordinates effective action in a direct calculation. The computation is performed using effective field methods based on Feynman diagrams in momentumspace in $d = 3  2\varepsilon$ space dimensions. [...]

HEJ 2: High Energy Resummation for Hadron Colliders
[arXiv:1902.08430; DESY19028; IPPP/19/13; MCnet1905]
We present HEJ 2, a new implementation of the High Energy Jets formalism for highenergy resummation in hadroncollider processes as a flexible Monte Carlo event generator. In combination with a conventional fixedorder event generator, HEJ 2 can be used to obtain greatly improved predictions for a number of phenomenologically important processes by adding allorder logarithmic corrections in $\hat{s}/p_\perp^2$.

Conformal field theory and the hot phase of threedimensional U(1) gauge theory
[arXiv:1903.00491; DESY19027]
We study the hightemperature phase of compact U(1) gauge theory in 2+1 dimensions, comparing the results of lattice calculations with analytical predictions from the conformalfieldtheory description of the lowtemperature phase of the bidimensional XY model. We focus on the twopoint correlation functions of probe charges and the fieldstrength operator, finding excellent quantitative agreement with the functional form and the continuously varying critical indices predicted by conformal field theory..

Measurements of the pseudorapidity distributions of charged hadrons produced in xenonxenon collisions at a nucleonnucleon centreofmass energy of $\sqrt{s_\mathrm{NN}} =$ 5.44 TeV are presented. The measurements are based on data collected by the CMS experiment at the LHC. [...]

Combinations of singletopquark production crosssection measurements and $f_{\rm LV}V_{tb}$ determinations at $\sqrt{s}=7$ and 8 TeV with the ATLAS and CMS experiments
[arXiv:1902.07158; CERNEP2019005]
This paper presents the combinations of singletopquark production crosssection measurements by the ATLAS and CMS Collaborations, using data from LHC protonproton collisions at $\sqrt{s}=7$ and 8 TeV corresponding to integrated luminosities of 1.17 to 5.1 fb$^{1}$ at $\sqrt{s}=7$ TeV, and 12.2 to 20.3 fb$^{1}$ at $\sqrt{s}=8$ TeV. These combinations are performed per centreofmass energy and for each production mode: $t$channel, $tW$, and $s$channel. [...]

Limits on contact interactions and leptoquarks at HERA
[arXiv:1902.03048; DESY19022]
Highprecision HERA data corresponding to a luminosity of around 1 fb$^{1}$ have been used in the framework of $eeqq$ contact interactions (CI) to set limits on possible highenergy contributions beyond the Standard Model to electronquark scattering. Measurements of the inclusive deep inelastic cross sections in neutral and charged current $ep$ scattering were considered. [...]

Fiveloop contributions to lowN nonsinglet anomalous dimensions in QCD
[arXiv:1812.11818; Nikhef2018066; DESY18227; LTH1191]
We present the first calculations of nexttonexttonexttonexttoleading order (N 4 LO) contributions to anomalous dimensions of spin N twist2 operators in perturbative QCD. Specifically, we have obtained the respective nonsinglet quark–quark anomalous dimensions at N=2 and N=3 to the fifth order in the strong coupling αs . [...]

Probing the photonic content of the proton using photoninduced dilepton production in $p+\textrm{Pb}$ collisions at the LHC
[arXiv:1901.06305; DESY19010]
We propose a new experimental method to probe the photon parton distribution function inside the proton (photon PDF) at LHC energies. The method is based on the measurement of dilepton production from the $\gamma p\rightarrow\ell^+\ell^+X$ reaction in protonlead collisions. [...]

Measurements of the pp$\to$WZ inclusive and differential production cross section and constraints on charged anomalous triple gauge couplings at $\sqrt{s} =$ 13 TeV
[arXiv:1901.03428; CMSSMP18002; CERNEP2018322]
The WZ production cross section is measured in protonproton collisions at a centreofmass energy $\sqrt{s} =$ 13 TeV using data collected with the CMS detector, corresponding to an integrated luminosity of 35.9 fb$^{1}$. 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.
