In this talk, we show how the swampland conjecture, which has
recently been attracting attention in string theory and gravity
theory, relates to the slow-roll condition of inflation. First, we
will briefly explain the reason why we focus on the swampland
conjecture to investigate the dynamics of inflation. Next, we discuss

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.
Gr@v students visit Brazil
Gr@v Ph.D. students Alexandre Pombo, João Oliveira and Jorge Delgado visited Belém, Brazil as members of the FunFiCO Marie Curie RISE project. Their visit coincided with the VII Amazonian Workshop on Gravity and analogue models, where they presented their work, and the Amazonian High Studies School in Theoretical Physics where they attended courses on Numerical Relativity and Gravitational Lensing.
