Measurement of the differential W→ µ +ν cross section at high transverse masses at √s=13 TeV with the ATLAS detector. — •Johanna Wanda Kraus, Frederic Schröder, and Frank Ellinghaus — Bergische Universität Wuppertal
The cross section of the charged-current Drell-Yan process in the decay W→ µ +ν is measured with data taken with the ATLAS detector from pp-collisions at a center-of-mass energy of √s=13 TeV.
While the inclusive cross-section is well-known, a differential measurement at very high transverse masses is done for the first time. The cross-section will also be measured double-differentially in the transverse mass of the W-boson mTW and the pseudorapidity of the lepton.
This measurement is important since it can be used to constrain the parton distribution function of the proton as well as electroweak parameters.
An overview over the analysis strategy and progress will be given.
