Studies of X(3872)X(3872) and ψ(2S)ψ(2S) production in pˉpp¯p collisions at 1.96 TeV / D0 Collaboration
We present various properties of the production of the X(3872)X(3872) and ψ(2S)ψ(2S) states based on 10.4 fb11 collected by D0 experiment in Tevatron pˉpp¯p collisions at ss = 1.96 TeV. For both states, we measure the nonprompt fraction fNPfNP of the inclusive production rate due to decays of bb-flavored hadrons. [...]

Study of the normalized transverse momentum distribution of WW bosons produced in pˉpp¯p collisions at s=1.96s=1.96 TeV / D0 Collaboration
We present a study of the normalized transverse momentum distribution of WW bosons produced in pˉpp¯p collisions, using data corresponding to an integrated luminosity of 4.35 fb11 collected with the D0 detector at the Fermilab Tevatron collider at s=1.96s=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 WW boson mass.

Properties of Z±c(3900)Z±c(3900) produced in pˉpp¯p collision / D0 Collaboration
We study the production of the exotic charged charmonium-like state Z±c(3900)Z±c(3900) in pˉpp¯p collisions through the sequential process ψ(4260)Z±c(3900)πψ(4260)Z±c(3900)π, Z±c(3900)J/ψπ±Z±c(3900)J/ψπ±. Using the subsample of candidates originating from semi-inclusive weak decays of bb-flavored hadrons, we measure the invariant mass and natural width to be M=3902.6+5.25.0(stat)+3.31.4(syst)M=3902.6+5.25.0(stat)+3.31.4(syst) MeV and Γ=32+2821(stat)+267(syst)Γ=32+2821(stat)+267(syst) MeV, respectively.

Measurement of the direct CP violating charge asymmetry in B±μ±νμD0B±μ±νμD0 decays / D0 Collaboration
We present the first measurement of the CP violating charge asymmetry in B±μ±νμD0B±μ±νμD0 decays using the full Run II integrated luminosity of 10.4 fb11 in proton-antiproton collisions collected with the D0 detector at the Fermilab Tevatron Collider. We measure a difference in the yield of BB and B+B+ mesons in these decays by fitting the reconstructed invariant mass distributions. [...]

Project Everware - running other people's code doesn't have to be painful / HEAD, Tim (speaker) (Ecole Polytechnique Federale de Lausanne (CH))
Everware is a project that allows you to edit and run someone else's code with one click, even if that code has complicated setup instructions. The main aim of the project is to encourage reuse of software between researchers by making it easy and risk free to try out someone else's code..

Data science in LHCb / HEAD, Tim (speaker) (Ecole Polytechnique Federale de Lausanne (CH))
Machine learning is used at all stages of the LHCb experiment. It is routinely used: in the process of deciding which data to record and which to reject forever, as part of the reconstruction algorithms (feature engineering), and in the extraction of physics results from our data. This talk will highlight current use cases, as well as ideas for ambitious future applications, and how we can collaborate on them.

Inclusive production of the X(4140)X(4140) state in p¯pp¯¯¯p collisions at D0 / D0 Collaboration
We present a study of the inclusive production of the X(4140)X(4140) with the decay to the J/ψϕJ/ψϕ final state in hadronic collisions. Based on 10.4 fb110.4 fb1 of p¯pp¯¯¯p collision data collected by the D0 experiment at the Fermilab Tevatron collider, we report the first evidence for the prompt production of X(4140)X(4140) and find the fraction of X(4140)X(4140) events originating from bb hadrons to be fb=0.39±0.07(stat)±0.10(syst)fb=0.39±0.07(stat)±0.10(syst) [...]

Simultaneous measurement of forward-backward asymmetry and top polarization in dilepton final states from tˉtt¯t production at the Tevatron / D0 Collaboration
We present a simultaneous measurement of the forward-backward asymmetry and the top-quark polarization in tˉtt¯t production in dilepton final states using 9.7 fb11 of proton-antiproton collisions at s=1.96s=1.96 TeV with the D0 detector. To reconstruct the distributions of kinematic observables we employ a matrix element technique that calculates the likelihood of the possible tˉtt¯t kinematic configurations. [...]
