Subject: Measurements of Z Transverse Momentum Shape Using a Novel Variable at the CMS Detector

The understanding of transverse momentum of the Z boson in a proton-proton collision is important, and yet at low values, measurements of transverse momentum are not in agreement with proposed models. This talk describes a measurement of the physics behind the transverse momentum of the Z boson using a novel variable (phi-star) that increases the precision of the analysis beyond that of a conventional transverse momentum measurement.
