# Measurements of inclusive $W+$jets production rates as a function of jet transverse momentum in $p\bar{p}$ collisions at $\sqrt{s}=1.96$~TeV

### Description

This Letter describes measurements of inclusive W({yields} e{nu}) + n jet cross sections (n = 1-4), presented as total inclusive cross sections and differentially in the n{sup th} jet transverse momentum. The measurements are made using data corresponding to an integrated luminosity of 4.2 fb{sup -1} collected by the D0 detector at the Fermilab Tevatron Collider, and achieve considerably smaller uncertainties on W+jets production cross sections than previous measurements. The measurements are compared to next-to-leading order perturbative QCD (pQCD) calculations in the n = 1-3 jet multiplicity bins and to leading order pQCD calculations in the 4-jet bin. The measurements ... continued below

### Description

This Letter describes measurements of inclusive W({yields} e{nu}) + n jet cross sections (n = 1-4), presented as total inclusive cross sections and differentially in the n{sup th} jet transverse momentum. The measurements are made using data corresponding to an integrated luminosity of 4.2 fb{sup -1} collected by the D0 detector at the Fermilab Tevatron Collider, and achieve considerably smaller uncertainties on W+jets production cross sections than previous measurements. The measurements are compared to next-to-leading order perturbative QCD (pQCD) calculations in the n = 1-3 jet multiplicity bins and to leading order pQCD calculations in the 4-jet bin. The measurements are generally in agreement with pQCD predictions, although certain regions of phase space are identified where the calculations could be improved.
