GAMBIT -- a Global And Modular Bsm Inference Tool

Modern science usually provides both lots of data and very complicated models for the part of reality it is trying to describe. Sometimes there is even so much data, and the models are so complicated, that it becomes difficult to make full use of the data in deciding between models, or finding their properties. The main goal of the GAMBIT project is to write a software tool to help physicists do just that.

About the project

We live in the time of Big Data. Our fantastic technical ability to measure and record the world around us with great precision floods us with information. This is true both in our daily lives and in science. Mirroring this, our understanding of the world has advanced to very detailed and complicated models in most fields; models with many parameters and with great predictive power for many possible measurements. The data and the models have even become so unwieldy as to pose a problem: we are constantly challenged to apply the full power of the data to our models, in order to decide between competing models, and to establish the properties of a particular model. It is to meet this challenge in the field of particle and astroparticle physics that we started the GAMBIT Collaboration in 2012.

Objective

The main objective of the GAMBIT project is to deliver an open source computational tool able to deal with the full set of all relevant particle and astrophysical data, and its statistically correct application to any new physics models attempting to describe the basic building blocks of the Universe.

Outcomes

We have released version 1.0.0 of the GAMBIT software. The code can be found on HepForge and as a GitHub repository.

Financing

Work on GAMBIT in Oslo is partially financed by the Research Council of Norway (RCN) and the University of Oslo through a four-year FRIPRO/Fellesløftet grant for young research talents starting in the fall of 2014. It is also supported by the Faculty of Mathematics and Natural Sciences at the University of Oslo through its Strategic Dark matter Initiative.

Collaboration

The GAMBIT Collaboration consists of around 30 physicist, both theorists and experimentalists, from all over the world. Current participating institutions are: Aachen University, University of Adelaide, CERN, University of Edinburgh, GRAPPA Institute, University of Amsterdam, Harvard University, Imperial College London, Monash University, Technical University Munich, NORDITA, the Oskar Klein Centre, Stockholm University and the University of Zurich. The Collaboration includes members of the AMS-02, ATLAS, CDMS, CTA, DARWIN, DM-ICE, Fermi-LAT, HESS, IceCube, LHCb and XENON experiments, as well as developers of the public computer codes DarkSUSY, FlexibleSUSY, IsaJet, SoftSUSY and SuperIso.

Tools

You can find the open source GAMBIT software here together with documentation of the code.
