Parton Luminosities 2011

Parton luminosities are convenient for estimating how the physics potential of Large Hadron Collider experiments depends on the energy of the proton beams. In arXiv:1101.3201 I present parton luminosities, ratios of parton luminosities, and contours of fixed parton luminosity for gluon-gluon, u-dbar, light-quark–light-quark, and gluon–light-quark interactions over the energy range relevant to the Large Hadron Collider, along with example analyses for specific processes. I quantify the advantage of increasing the beam energy from 3.5 TeV to 4 TeV. The plots are available here as full-page pdf files. Click on a thumbnail to retrieve a plot, or download an archive containing all twenty-four plots from the paper, plus two plots combining all the 8-TeV to 7-TeV ratios.
