We present a comprehensive analysis of inclusive W(\to e\nu)+n-jet (n\geq1,2,3,4) production in proton-antiproton collisions at a center-of-mass energyof 1.96 TeV at the Tevatron collider using a 3.7 fb^{-1} dataset collected bythe D0 detector. Differential cross sections are presented as a function of thejet rapidities (y), lepton transverse momentum (p_T) and pseudorapidity (\eta),the scalar sum of the transverse energies of the W boson and all jets (H_T),leading dijet p_T and invariant mass, dijet rapidity separations for a varietyof jet pairings for p_T-ordered and angular-ordered jets, dijet opening angle,dijet azimuthal angular separations for p_T-ordered and angular-ordered jets,and W boson transverse momentum. The mean number of jets in an event containinga W boson is measured as a function of H_T, and as a function of the rapidityseparations between the two highest-p_T jets and between the most widelyseparated jets in rapidity. Finally, the probability for third-jet emission inevents containing a W boson and at least two jets is studied by measuring thefraction of events in the inclusive W+2-jet sample that contain a third jetover a p_T threshold. The analysis employs a regularized singular valuedecomposition technique to accurately correct for detector effects and for thepresence of backgrounds. The corrected data are compared to particle levelnext-to-leading order perturbative QCD predictions, predictions from all-orderresummation approaches, and a variety of leading-order and matrix-element plusparton-shower event generators. Regions of the phase space where there isagreement or disagreement with the data are discussed for the different modelstested.
