Joint HEP/Theory Seminar: Precision calculations for the LHC using MCFM
Tuesday, September 19, 2017
1:30 pm - 2:30 pm
John M. Campbell, Fermilab
The impressive size of the datasets collected by the LHC experiments, together with the ever-increasing sophistication of the accompanying analyses, means that experimental uncertainties at the level of a few percent are becoming more common. In order to maximize the information that can be inferred from such analyses, theoretical calculations of signal and background processes should be of commensurate precision. This talk outlines the current status of precision theoretical predictions and describes the calculation of some of them in the next-to-next-to-leading order Monte Carlo program MCFM. Examples include predictions for diphoton, Z+photon, and photon+jet production, as well as applications to searches for dark matter at the LHC.
