Measurement of the production cross section for <em>Z/γ*</em> in association with jets in <em>pp</em> collisions at √s=7  TeV with the ATLAS detector

Jets are reconstructed in data and Monte Carlo simulated events using calorimeter towers with transverse momenta [16] above 0:1 GeV=c.. The towers associated with the

Two data sets are used for this measurement: a sample of jets from inclusive jet production, containing only a negligible amount of b -jets, and a sample where the heavy-flavor

Since the Z þ c jet cross section in the data is unknown and the simulation may not accurately describe the rate of light jets that are reconstructed with a secondary vertex,

Because of their dependence on the number of tracks in the bunch crossing, a variable closely related to the event particle multiplicity, both the trigger and the vertex effi-

Distributions of the missing transverse energy, E T miss , of electron (a) and muon (b) can- didates for data and Monte-Carlo simulation, broken down into the signal and

Sources of systematic uncertainty in the background yield of tagged b jets include the uncertainty in the b -jet tagging efficiency in the data (a relative 6% uncertainty on all

The differential cross section has been measured as a function of the prompt photon transverse energy between 15 and 100 GeV, in the three pseudorapidity intervals j j &lt; 0:6, 0:6
