Description
INCL is one of the intranuclear cascade codes that is still being developed and implemented in particle transport codes. It was last presented at a SATIF workshop in 2010. Since then, INCL has been updated and in this presentation, we propose to show the latest developments and perspectives.
The new capabilities of INCL are linked to the extension of the energy range, new projectiles and the addition of new quantum effects. INCL can be used with energies of up to ~20 GeV. This has been made possible by the implementation of multiple pion channels, then by the addition of eta and omega mesons, and finally by the ability to handle strange particles such as the Kaon meson and the Lambda and Sigma baryons. The projectiles available range from nucleons and pions to light (hyper)clusters with masses of 18 or less, including strange particles (K, Lambda, Sigma). Recently, a new type of reaction has been introduced, using antiprotons as projectiles. This has been driven by demand from people carrying out experiments at ELENA (CERN) with antiprotons at rest, and from people at FAIR (GSI) with antiprotons in flight. Concerning quantum effects, the possibility of low-energy nucleons in the target nucleus moving further away from the centre than a classical particle in a potential well has been made possible by a better description of the radial density distributions of nucleons based on a Skyrme interaction.
All these new capabilities are available in the Geant4 transport codes.
In addition to these extensions, a new study was launched in 2024: errors and associated uncertainties, and parameter optimisation. This project has been funded for four years by the French National Research Agency (ANR).
In a few words, we will present the objective of the project, what has been done previously and what will be done in the future.
This will provide an up-to-date picture of INCL.
