Compatibility and combination of world W-boson mass measurements / LHC-TeV MW Working Group Collaboration
The compatibility of W-boson mass measurements performed by the ATLAS, LHCb, CDF, and D0 experiments is studied using a coherent framework with theory uncertainty correlations. The measurements are combined using a number of recent sets of parton distribution functions (PDF), and are further combined with the average value of measurements from the Large Electron-Positron collider.

Up and Down Quark Structure of the Proton / D0 Collaboration
We measure proton structure parameters sensitive primarily to valence quarks using 8.6 fb$^{-1}$ of data collected by the D0 detector in $\sqrt{s}=1.96$ TeV $p\bar{p}$ collisions at the Fermilab Tevatron. We exploit the property of the forward-backward asymmetry in dilepton events to be factorized in to distinct structure parameters and electroweak quark-level asymmetries. [...]

We report on the first production of an antihydrogen beam by charge exchange of 6.1 keV antiprotons with a cloud of positronium in the GBAR experiment at CERN. The antiproton beam was delivered by the AD/ELENA facility. [...]

Positron accumulation in the GBAR experiment / GBAR Collaboration
We present a description of the GBAR positron (e+) trapping apparatus, which consists of a three stage Buffer Gas Trap (BGT) followed by a High Field Penning Trap (HFT), and discuss its performance. The overall goal of the GBAR experiment is to measure the acceleration of the neutral antihydrogen (H) atom in the terrestrial gravitational field by neutralising a positive antihydrogen ion (H+), which has been cooled to a low temperature, and observing the subsequent H annihilation following free fall. [...]

A pulsed high-voltage decelerator system to deliver low-energy antiprotons / Husson, A (IJCLab, Orsay) ; Kim, B H (Seoul Natl. U., Dept. Phys. Astron.) ; Welker, A (CERN) ; Charlton, M (Swansea U.) ; Choi, J J (Seoul Natl. U., Dept. Phys. Astron.) ; Chung, M (UNIST, Ulsan) ; Cladé, P (Paris, Lab.

The GBAR (Gravitational Behavior of Antihydrogen at Rest) experiment at CERN requires efficient deceleration of 100 keV antiprotons provided by the new ELENA synchrotron ring to synthesize antihydrogen. This is accomplished using electrostatic deceleration optics and a drift tube that is designed to switch from -99 kV to ground when the antiproton bunch is inside – essentially a charged particle “elevator” – producing a 1 keV pulse.

Comparison of $pp$ and $p \bar{p}$ differential elastic cross sections and observation of the exchange of a colorless $C$-odd gluonic compound / D0 Collaboration
We describe a quantitative analysis comparing the p anti-p elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a mainly model-independent approach. The TOTEM cross sections extrapolated to a center-of-mass energy of sqrt(s) = 1.96 TeV are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the pp cross section.

Accumulation of Positrons from a LINAC Based Source / GBAR Collaboration
The GBAR experiment aims to measure the gravitational acceleration of antihydrogen H. It will use H + ions formed by the interaction of antiprotons with a dense positronium cloud, which will require about $10^{10}$ positrons to produce one H + [...]

Development of a PbWO$_4$ Detector for Single-Shot Positron Annihilation Lifetime Spectroscopy at the GBAR Experiment / Kim, B H (Seoul Natl. U.) ; Choi, J J (Seoul Natl. U.) ; Chung, M (UNIST, Ulsan) ; Cladé, P (Paris, Lab. Kastler Brossel) ; Comini, P (IRFU, Saclay) ; Crivelli, P (Zurich, ETH) ; Crépin, P-P (Paris, Lab. Kastler Brossel) ; Dalkarov, O (Lebedev Inst.) ; Debu, P (IRFU, Saclay) ; Dodd, L (Swansea U.) et al.
We have developed a PbWO$_{4}$ (PWO) detector with a large dynamic range to measure the intensity of a positron beam and the absolute density of the ortho-positronium ($\mathrm{o-Ps}$) cloud it creates. A simulation study shows that a setup based on such detectors may be used to determine the angular distribution of the emission and reflection of $\mathrm{o-Ps}$ to reduce part of the uncertainties of the measurement.

Studies of $X(3872)$ and $\psi(2S)$ production in $p\bar{p}$ collisions at 1.96 TeV / D0 Collaboration
We present various properties of the production of the $X(3872)$ and $\psi(2S)$ states based on 10.4 fb$^{-1}$ collected by D0 experiment in Tevatron $p \bar p$ collisions at $\sqrt{s}$ = 1.96 TeV. For both states, we measure the nonprompt fraction $f_{NP}$ of the inclusive production rate due to decays of $b$-flavored hadrons. [...]
