Calculation of the Z+ jet cross section including transverse momenta of initial partons

Transverse momenta of partons in high-energy scatter- ing processes

The central topic of these lectures is the proton. We want to grasp its structure. On the one hand as part of our quest to understand the heart of the matter, at least the visible matter, in our universe. On the other hand because protons besides electrons are basic tools in experiments that probe the fundamental forces in nature. Therefore we want to use their properties, global ones like ener...

Jet Missing Transverse Momenta for Quark-gluon Plasma Thermometry

At the LHC, where hard multi-jet events are common, large imbalances in the total jet-pT can arise due to the interaction of jets with the plasma formed in heavy-ion collisions. We find that this missing-pT spectrum yields a measurement of the initial temperature of the plasma. Using commonly accepted guesses for this temperature, and ISAJET estimates for jet cross sections, we predict an order...

Calculation of Z plus Four Jet Production at the Tevatron

We present the first calculation of Z + 4 jet production with heavy quark flavor identification at the Tevatron pp̄ collider. The Z + 4 jet channel is especially interesting as a normalizer for the W + 4 jet background to top quark signals, as a background to a possible t → cZ flavor-changing neutral-current (FCNC) decay signal, and as a background to missing-pT signals from gluino pairs. We als...
