11. Direct detection of pNG dark matter in the S2HDM

Pedro Gabriel

Pseudo-Nambu-Goldstone (pNG) dark matter models are popular for having a rich phenomenology and for being compatible with many existing observations. These models have the distinct feature of having negligible DM direct detection cross section at leading order, being that the first relevant contribution to the cross section comes from the one-loop electroweak corrections. These one-loop...

12. Hubble tension in a nonminimally coupled curvature-matter gravity model

Miguel Barroso Varela

The presently open problem of the Hubble tension is shown to be removed in the context of a modified theory of gravity with a non-minimal coupling between curvature and matter. By evolving the cosmological parameters that match the cosmic microwave background data until their values from direct late-time measurements, we will show how to obtain an agreement between different experimental...

6. Orbifold stability of asymptotic GUTs

Anca Preda

In the realm of higher-dimensional grand unified theories (GUTs), the technique of orbifolding has emerged as a powerful tool to achieve spontaneous symmetry breaking by geometrical means. We use this tool to analyze the most general 5D GUT models based on the gauge groups SU(N), Sp(2N) and SO(N). We find a new physical consistency requirement, which these models have to satisfy in order to be...
