Contur - Constraints On New Theories Using Rivet

The original Contur procedure is defined in a ‘white paper’, which should be used as a reference for the method. More detail is also given here.

Currently, Contur produces combined sensitivity limits derived from comparisons between theoretical BSM simulations and data at the particle-level. That is, the theory simulates a fully-exclusive final state, and the data have been corrected for detector effects.

Professor

Professor is a tuning tool for Monte Carlo event generators, based on the ideas described in “Tuning and Test of Fragmentation Models Based on Identified Particles and Precision Event Shape Data” (Z. Phys., C73 (1996) 11-60).

Fundamentally, the idea of Professor is to reduce the exponentially expensive process of brute-force tuning to a scaling closer to a power law in the number of parameters, while allowing for massive parallelisation and systematically improving the scan results by use of a deterministic parameterisation of the generator’s response to changes in the steering parameters.

The approach is not limited to MC tuning: any situation which can benefit from fast parameterisation of histogram values can use Professor!

YODA - Yet more Objects for Data Analysis

YODA is a small set of data analysis (specifically histogramming) classes being developed by MCnet members as a lightweight common system for MC event generator validation analyses, particularly as the core histogramming system in Rivet.

YODA is a refreshingly clean, natural and powerful way to do histogramming… and there are plenty of improvements still to come. Our mission is to make the most powerful, expressive, and focused approach to binned computational data handling, with the nicest possible balance of power and simplicity in the user interface.

MCplots

MCPLOTS is intended as a simple browsable repository of MC (Monte Carlo) plots comparing High Energy Physics event generators to a wide variety of available experimental data, for tuning and reference purposes. Apart from individual plots contained in papers and presentations, there has not previously been any central database where people can quickly see how tune X of version Y of generator Z looks on distribution D. The idea with mcplots is to provide such a repository, mainly based on the Rivet analysis tool.

AGILe

AGILe is A Generator Interface Library (& executable), i.e. a uniform object oriented C++ interface for a variety of Fortran-based Monte Carlo event generators. The role of AGILe is to provide a standard steering interface for Fortran generator codes which usually do not come with an executable, usually need to be recompiled to change parameter settings, and cannot write output into the C++ HepMC event record: AGILe remedies all of these defects.

With the move to the C++ generation of MC event generators, AGILe is no longer needed for most collider physics applications.

The code remains available, but has not been actively maintained since ~2014
