    Description
    Consistent truncations have proven to be one of the main tools to study low-dimensional effective theories of string theories. In this talk, I will discuss how new U-duality covariant formulations of higher-dimensional supergravities, Exceptional Generalised Geometries (EGG) and Exceptional Field Theories (ExFT), can be used to classify the possible consistent truncations that can be obtained from such higher-dimensional supergravities. As an application, I will introduce a new D=4 maximal, tromboneful gauged supergravity relevant for the physics of M5-branes first obtained by EGG techniques and show how ExFT can be used to obtain a subsector of the global Kaluza-Klein spectrum of masses.
