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 pro…

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 …

Inclusive production of the $P_c$ resonances in $p \\overline p $\n collisions Open
We present a study of the inclusive production in $p \\overline p $ collisions\nof the pentaquark states $P_c(4440)$ and $P_c(4457)$ with the decay to the\n$J/\\psi p$ final state previously observed by the LHCb experiment. Using a\nsample…

CMS: Search for heavy resonances decaying to a top quark and a bottom quark in the lepton+jets final state in proton–proton collisions at 13TeV Open
A search is presented for narrow heavy resonances decaying to a top quark and a bottom quark using data collected by the CMS experiment at √s=13TeV in 2016. The data set analyzed corresponds to an integrated luminosity of 35.9fb−1. Final s…

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…

CMS: Search for lepton flavour violating decays of heavy resonancesand quantum black holes to an eμ pair in proton–protoncollisions at√s = 8 TeV Open
A search for narrow resonances decaying to an electron and a muon is presented. The eμ mass spectrum is also investigated for non-resonant contributions from the production of quantum black holes (QBHs). The analysis is performed using dat…

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 p (p) over bar 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…

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 …

Precise measurement of the top quark mass in dilepton decays using optimized neutrino weighting Open
We measure the top quark mass in dilepton final states of t (t) over bar events in p (p) over bar collisions at root s = 1.96 TeV, using data corresponding to an integrated luminosity of 9.7 fb(-1) at the Fermilab Tevatron Collider. The an…

We present a simultaneous measurement of the forward-backward asymmetry and the top-quark polarization in tt¯ production in dilepton final states using 9.7 fb−1 of proton-antiproton collisions at s√=1.96 TeV with the D0 detector. To recons…
