WG4 QCD and Hadronic Final States
We present recent results on heavy flavor jet production in association with weak vector bosons using proton-antiproton collision data collected with the D0 detector at center of mass energy sqrt{s}=1.96 TeV. We discuss in particular the measurements of W+b/c-jet production cross-sections and the ratio of cross-sections, sigma(Z+2b-jet)/sigma(Z+2jets). Study of these processes provide tests...

WG4 QCD and Hadronic Final States
H1 and ZEUS have published single-differential cross sections for inclusive D* meson production in deep-inelastic ep scattering at HERA from their respective final data sets. These cross sections are combined in the common visible phase space region of photon virtuality Q² > 5 GeV², electron inelasticity 0.02 < y < 0.7 and the D* meson's transverse momentum p_T (D*)> 1.5 GeV and pseudorapidity...

WG4 QCD and Hadronic Final States
We present a measurement of the forward-backward asymmetry in the production of B± mesons, Λb baryons and Λ baryons in 10.4 fb−1 of ppbar collisions at √s=1.96 TeV collected by the D0 experiment during Run II of the Tevatron collider. Nonzero asymmetries would indicate a preference for a particular flavor, i.e., b quark or b antiquark, to be produced in the direction of the proton beam. These...

WG5 Heavy Flavours
The LHC is the hardron collider with highest energy in the history. Taking the LHC run 1 data into account and considering more flexible parametrization, the CTEQ-TEA group study its impact on Parton distribution function, the CT14 PDFs. In this talk, we will present the recent study on heavy flavors base on the preliminary CT14 candidate.
