Cosmology

Cosmology is the study of the large scale structure of the Universe, as well as its dynamics. Our group has been involved in the study and development of cosmological models, in particular to explain the accelerated phases of the cosmological evolution, dubbed inflationary phases.

For our latest developments/activities in this area, please see the listing below.

In recent years several anomalies have been observed in decays of B-mesons. We give first a brief overview on the experimental situation. It is well know that these anomalies can be explained by adding leptoquarks or extra vector-bosons to the SM particle content.
