Sharpening the species scale.
In a quantum theory of gravity, the species scale can be defined as the scale at which the Einstein effective action breaks down and higher-curvature corrections become important. Interestingly, such corrections are related to the sizes of minimal black holes in gravitational theories. Therefore, understanding properties of the species scale can shed light on fundamental aspects of quantum gravity and have important applications to phenomenology. In this talk, I will introduce the species scale as a moduli-dependent quantity in supersymmetric theories and explore a diverse set of examples within string theory. This journey through different dimensions will provide evidence for a global bound of the species scale over its moduli space.
