Computational Particle Physics refers to the methods and computing tools developed in and used by particle physics research. Particle physics is a branch of Physics that studies the elementary constituents of Matter and Radiation, and the interactions between them Like Computational Chemistry or Computational Biology, it is, for particle physics both a specific branch and an interdisciplinary field relying on computer science, theoretical and experimental particle physics, mathematics,. Computational chemistry is a branch of Chemistry that uses computers to assist in solving chemical problems Computational biology is an interdisciplinary field that applies the techniques of Computer science, Applied mathematics, and Statistics to address problems Particle physics is a branch of Physics that studies the elementary constituents of Matter and Radiation, and the interactions between them . . The main fields of computational particle physics are:
- Lattice field theory numerical computations
- Automatic calculation of particle interaction or decay
- Event generators
Computing tools
- Computer algebra: Many of the computer algebra language has been developed initially to help particle physics calculations: Reduce, Mathematica, Schoonship, Form, . In Physics, lattice field theory is the study of lattice models of Quantum field theory, that is of field theory on a spacetime that has been discretized The automatic calculation of particle interaction or decay is part of the Computational particle physics branch Event generators are Software libraries that generate simulated high-energy Particle physics events. A computer algebra system ( CAS) is a software program that facilitates Symbolic mathematics. REDUCE is a general-purpose Computer algebra system geared towardsapplications in physics Mathematica is a computer program used widely in scientific engineering and mathematical fields . .
- Data Grid: The largest planed use of the GRID systems will be for the analysis of the LHC produced data. A data grid is a Grid computing system that deals with data &mdash the controlled sharing and management of large amounts of distributed data Large software packages have been developed to support this application like the LHC Computing GRID LCG.
