The Differential cross section distribution of Drell-Yan dielectron pairs in the z boson mass region
- Univ. of Rochester, NY (United States)
We report on a measurement of the rapidity distribution, dσ/dy, for Z=Drell-Yan → ee events produced in p$$\bar{p}$$ collisions at √s = 1.96 TeV. The data sample consists of 2.13 fb-1 corresponding to about 160,000 Z/Drell-Yan → ee candidates in the Z boson mass region collected by the Collider Detector at Fermilab. The dσ/dy distribution, which is measured over the full kinematic range for e+e- pairs in the invariant mass range 66 < Mee < 116 GeV/c2, is compared with theory predictions. There is good agreement between the data and predictions of Quantum Chromodynamics in Next to Leading Order with the CTEQ6.1M Parton Distribution Functions.
