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. The emphasis of the code is on user flexibility and rapid evaluation. It is publicly available at https://github.com/earlyuniverse/ulysses

  1. Thermal leptogenesis in minimal unified models

    hep-ph 2025-06 conditional novelty 4.0 of 10

    Thermal leptogenesis in minimal flipped SU(5) and SO(10) models tightly constrains their flavour parameters, yielding a lightest-neutrino mass below 0.03 eV and a B-L breaking scale near 10^12.5 GeV.

  2. Baryogenesis through leptogenesis in the minimal flipped $SU(5)$ with radiative seesaw

    hep-ph 2025-06 conditional novelty 2.0 of 10

    In the minimal flipped SU(5) model with radiative seesaw, successful thermal leptogenesis implies an upper limit on the lightest neutrino mass of about 3 x 10^-2 eV, testable at KATRIN.
