Consistent Effective Field Theories


Abstract

Even without reference to ultraviolet completions that include gravity (like e.g. string theory), generic effective field theories might be inconsistent and be part of a "swampland". These lectures aim at introducing the basic constraints that a consistent Effective Field Theory (EFT) should satisfy. Positivity bounds on Wilson coefficients and restrictions from gauge anomaly cancellation will be illustrated at an introductory level. Several simple examples will be worked out, both in a top-down and in a bottom up-approach.
