ULYSSES: Universal LeptogeneSiS Equation Solver

Understand

ULYSSES is a python package that calculates the baryon asymmetry produced from leptogenesis in the context of a type-I seesaw mechanism.

• The code solves the semi-classical Boltzmann equations for points in the model parameter space as specified by the user.
• We provide a selection of predefined Boltzmann equations as well as a plugin mechanism for externally provided models of leptogenesis.
• Furthermore, the ULYSSES code provides tools for multi-dimensional parameter space exploration.
