Patriot
Physics Analysis & Tools Required to Investigate Our Theories

PATRIOT is a project that aims to provide better predictions of physics events for

the high-Pt physics program of Run2.

Central to Patriot is an enstore or mass storage repository for files describing the high-Pt physics predictions. These are typically stored as StdHep files which can be handled by CDF and D0 and run through detector and triggering simulations. The definition of these datasets in the CDF and D0 data handling system SAM is under way.

Patriot relies heavily on a new generation of Monte Carlo tools to calculate the hard structure of high-Pt events and the more venerable event generators to make particle level predictions. Many of these tools are described here.

An early informational database, describing the types of data files stored in Patriot, is provided below. A new database is under development.

Details of one prediction of interest for Run2, which involves the merging of W+0 through W+4 parton matrix element predictions using the event generator Pythia, are described here. Figures describing the predictions are seen below.

Below are examples of events processed through the CDF and D0 detector simulations:

detailed properties of high-Pt events. Some of the essential features of particle-level events must be described by non-perturbative functions, whose form is often constrained by theory, but which must be ultimately tuned to data.

Details of this undertaking, and other related issues, can be found in the collection of transparencies from the MC4Run2 meetings, provided below.
