Robust model-to-data comparisons
HZTool is a library of routines which will allow you to reproduce an
experimental result using the four-vector final state from Monte Carlo
Version 4.3 of HZTool has now been released.

Version 4.1 of HZTool has now been released.
This release allows the LEP gamma-gamma analysis routines to be run in a mode where direct, single and doubly resolved photoproduction are produced in a single Monte Carlo run. Available as a tarball on the downloads page. Changes in version 4.1

- HZSteer is a related
a project which provides executable main programs using HZTool.
- Rivet aims to
provide similar functionality in a C++, objected-oriented manner.
- The RunMC
package provides a nice front-end for HZTool (as well as other good things).

The original idea for HZTOOL emerged in the workshop on
Future Physics at HERA. The
original reference is
J. Bromley et al, Hamburg 1995/96, Future physics at HERA, vol. 1, 611-612.
The package was managed by Tancredi Carli for quite some time and many
people have contributed routines and general development to HZTool
since it first appeared. Tancredi's old web page can be found here.
