Up and down quark structure of the proton Open
We report an improved measurement of the valence u and d quark distributions from the forward-backward asymmetry in the Drell-Yan process using 8.6 fb−1 of data collected with the D0 detector in pp¯ collisions at s=1.96. This analysis prov…

The International Linear Collider: Report to Snowmass 2021 Open
The International Linear Collider (ILC) is on the table now as a new global energy-frontier accelerator laboratory taking data in the 2030s. The ILC addresses key questions for our current understanding of particle physics. It is based on …

The Road Ahead for CODEX-b Open
In this Snowmass contribution we present a comprehensive status update on the progress and plans for the proposed CODEX-b detector, intended to search for long-lived particles beyond the Standard Model. We review the physics case for the p…

Search for strongly interacting massive particles generating trackless jets in proton-proton collisions at $\sqrt{s} = $ 13 TeV Open
A search for dark matter in the form of strongly interacting massive particles (SIMPs) using the CMS detector at the LHC is presented. The SIMPs would be produced in pairs that manifest themselves as pairs of jets without tracks. The energ…

Studies of $X(3872)$ and $\psi(2S)$ production in $p\bar{p}$ collisions at 1.96 TeV Open
We present various properties of the production of the $X(3872)$ and $ψ(2S)$ states based on $10.4 fb^{−1}$ collected by the D0 experiment in Tevatron $p\bar{p}$ collisions at $\sqrt{s}=1.96 TeV$. For both states, we measure the nonprompt …

Decentralised Multi-Robot Systems Towards Coordination in Real World Settings Open
In recent years, Multi-Robot Systems (MRS) have gained significant interest in research and in industry (Khandelwal and Stone, 2017; E. Schneider et al., 2016; Amato et al., 2015; Alonso-Mora et al., 2015b; Enright and Wurman, 2011). Manuf…

The Cosmic Ray Observatory Project A Statewide Outreach Education Experiment in Nebraska Open
The Cosmic Ray Observatory Project (CROP) is a statewide education and research experiment involving Nebraska high school students, teachers, and college undergraduates in the study of extended cosmic-ray air showers. A network of high sch…

Combination of D0 measurements of the top quark mass Open
We present a combination of measurements of the top quark mass by the D0 experiment in the lepton+jets and dilepton channels. We use all the data collected in Run I (1992–1996) at √s=1.8 TeV and Run II (2001–2011) at √s = 1.96 TeV of the T…

Exclusive and semi-exclusive $\pi^{+}\pi^-$ production in proton-proton collisions at $\sqrt{s} = 7$ TeV Open
A measurement is presented of the exclusive and semi-exclusive production of charged pion pairs in proton-proton collisions, $pp \to p(p^{*}) + \pi^{+}\pi^- + p(p^{*})$ here the $\pi^{+}\pi^-$ pair is emitted at central rapidities, and the…

Measurement of the top quark mass using the matrix element technique in dilepton final states Open
We present a measurement of the top quark mass in ppbar collisions at a center-of-mass energy of 1.96 TeV at the Fermilab Tevatron collider. The data were collected by the D0 experiment corresponding to an integrated luminosity of 9.7 fb-1…

Evidence for a [?] State Open
We report evidence for a narrow structure, X(5568), in the decay sequence X(5568) → [?], [?] → J/ψϕ, J/ψ → μ+μ−, ϕ → K+K−. This is evidence for the first instance of a hadronic state with valence quarks of four different flavors. The mass …
