Query: Physics Performance with the CMS Pixel Detector   A large fraction of the results produced by the LHC experiments during the
first run were made possible by precision vertexing detectors. The all-silicon
tracking detector of the CMS experiment uses a pixel detector to do vertexing.
This conference report uses four physics analyses as examples where pixel
detector are used to either reconstruct primary vertices, separate event tracks
from pileup, and/or determine displaced vertices.
