APFEL++ Ariane
The main feature of this version of APFEL++ is the implementation of the evolution of generalised parton distributions (GPDs). So far only leading-order unpolarised evolution is implemented but the structure allows for an easy extension to higher orders and polarised GPDs planned for the next future.
Additional functionalities newly implemented include:
- the possibility to handle evolution with explicitly scale dependent splitting functions,
- the implementation of polarised DIS structure functions up to next-to-leading order,
- new integration strategies. Specifically a 2D integrator and the Gauss-Kronrod algorithm (now set as a default).
This release also includes minor bug fixing and performance enhancements.
