Abstract: (Elsevier)

We present a measurement of the cross section for W boson production in association with at least one b -quark jet in proton–antiproton collisions. The measurement is made using data corresponding to an integrated luminosity of 6.1 fb−1 recorded with the D0 detector at the Fermilab Tevatron pp¯ Collider at s=1.96 TeV . We measure an inclusive cross section of σ(W(→μν)+b+X)=1.04±0.05(stat.)±0.12(syst.) pb and σ(W(→eν)+b+X)=1.00±0.04(stat.)±0.12(syst.) pb in the phase space defined by pTν>25 GeV , pTb-jet>20 GeV , |ηb-jet|<1.1 , and a muon (electron) with pTℓ>20 GeV and |ημ|<1.7 ( |ηe|<1.1 or 1.5<|ηe|<2.5 ). The combined result per lepton family is σ(W(→ℓν)+b+X)=1.05±0.12(stat.+syst.) pb for |ηℓ|<1.7 . The results are in agreement with predictions from next-to-leading order QCD calculations using mcfm , σ(W+b)⋅B(W→ℓν)=1.34−0.34+0.41(syst.) pb , and also with predictions from the sherpa and madgraph Monte Carlo event generators.

We use a standard right-handed coordinate system. The nominal collision point is the center of the detector with coordinate (0, 0, 0). The direction of the proton beam is the positive +z axis. The +x axis is horizontal, pointing away from the center of the Tevatron ring. The +y axis points vertically upwards. The polar angle, θ, is defined ned such that θ = 0 is the +z direction. The rapidity is defined as y = - ln [(E + pZ)/(E - pZ)], where E is the energy and pZ is the momentum component along the proton beam direction. Pseudorapidity is defined as η = - ln(tan θ 2 ). ϕ is defined as the azimuthal angle in the plane transverse to the proton beam direction

Since the longitudinal component of the momentum of the neutrinos is not measured, the measured properties of the W boson candidates are limited to their transverse energy and transverse mass, defined as MT = (p/ T + pℓ T )2 - (p/ x + pℓ x)2 - (p/ y + pℓ y)2 where p/ T is the magnitude of the missing transverse energy vector, pℓ T is the transverse momentum of the lepton and pℓ x and pℓ y (p/ x and p/ y) are the magnitude of the x and y components of the lepton’s momentum (missing transverse energy) respectively
