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. [...]

Building HEP Software with Spack: Experiences from Pilot Builds for Key4hep and Outlook for LCG Releases / Volkl, Valentin (CERN) ; Madlener, Thomas (DESY) ; Lin, Tao (Beijing, Inst. High Energy Phys.) ; Wang, Joseph (Hong Kong, Chinese U.) ; Konstantinov, Dmitri (Kurchatov Inst., Moscow) ; Razumov, Ivan (Kurchatov Inst., Moscow) ; Sailer, Andre (CERN) ; Ganis, Gerardo (CERN)
Consistent, efficient software builds and deployments are a common concern for all HEP experiments. This paper describes the evolution of the usage of the Spack package manager in HEP in the context of the LCG stacks and the current Spack-based management of Key4hep software. [...]

Optimizing Provisioning of LCG Software Stacks with Kubernetes / Bachmann, Richard (CERN ; Norwegian U. Sci. Tech.) ; Ganis, Gerardo (CERN) ; Konstantinov, Dmitri (Serpukhov, IHEP) ; Razumov, Ivan (Serpukhov, IHEP) ; Heinz, Johannes Martin (Hochschule, Eng. Econ., Karlsruhe)
The building, testing and deployment of coherent large software stacks is very challenging, in particular when they consist of the diverse set of packages required by the LHC*** experiments, the CERN Beams department and data analysis services such as SWAN. These software stacks comprise a large number of packages (Monte Carlo generators, machine learning tools, Python modules, HEP**** specific software), all available for several compilers, operating systems and hardware architectures.

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.

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. [...]

Study of the normalized transverse momentum distribution of $W$ bosons produced in $p \bar p$ collisions at $\sqrt{s}=1.96$ TeV / D0 Collaboration
We present a study of the normalized transverse momentum distribution of $W$ bosons produced in $p \bar p$ collisions, using data corresponding to an integrated luminosity of 4.35 fb$^{-1}$ collected with the D0 detector at the Fermilab Tevatron collider at $\sqrt{s}=1.96$ TeV. The measurement focuses on the transverse momentum region below 15 GeV, which is of special interest for electroweak precision measurements; it relies on the same detector calibration methods which were used for the precision measurement of the $W$ boson mass.

Geant-val: a web application for validation of detector simulations / Freyermuth, Luc (EISTI, Cergy) ; Konstantinov, Dmitri (CERN ; Serpukhov, IHEP) ; Latyshev, Grigorii (Serpukhov, IHEP) ; Razumov, Ivan (Serpukhov, IHEP ; CERN) ; Pokorski, Witold (CERN) ; Ribon, Alberto (CERN)
One of the key factors for the successful development of Monte-Carlo programs for physics simulations is to properly organize regression testing and validation. Geant4, the world-standard toolkit for HEP detector simulation, heavily relies on this activity. [...]

Inclusive production of the $P_c$ resonances in $p \overline p $ collisions / D0 Collaboration
We present a study of the inclusive production in $p \overline p $ collisions of the pentaquark states $P_c(4440)$ and $P_c(4457)$ with the decay to the $J/\psi p$ final state previously observed by the LHCb experiment. [...]

Properties of $Z_c^{\pm}(3900)$ produced in $p \bar p$ collision / D0 Collaboration
We study the production of the exotic charged charmonium-like state $Z_c^{\pm}(3900)$ in $p \bar p$ collisions through the sequential process $\psi(4260) \rightarrow Z_c^{\pm}(3900) \pi^{\mp}$, $Z_c^{\pm}(3900) \rightarrow J/\psi \pi^{\pm}$. Using the subsample of candidates originating from semi-inclusive weak decays of $b$-flavored hadrons, we measure the invariant mass and natural width to be $M=3902.6^{+5.2}_{-5.0}{\rm \thinspace (stat)}^{+3.3}_{-1.4}{\rm \thinspace (syst)}$ MeV and $\Gamma=32 ^{+28}_{-21}{\rm \thinspace (stat)} ^{+26}_{-7}{\rm \thinspace (syst)}$ MeV, respectively.
