Description

When data anomalies are observed, it is a common practice to assume some toy models, simplified models, or EFT and interpret the anomalies. In particular, one tends to minimize the number of new physical degrees of freedom, as well as the number of couplings. In this talk, I will describe a few examples in physics of flavors and dark matter, where this simple-minded approach leads to incorrect or unphysical results. Based on these observations, I will advocate criteria that the simplest model for data analysis must satisfy to avoid this problem.
