Running in the SMEFT
Guilherme Guedes (U. Granada and LIP)

In this talk, I will discuss the calculation of the renormalization group equations (RGEs) of theories extending the Standard Model effective field theory (SMEFT) with higher-dimensional operators or with a new degree of freedom. In the first case, I will explore the running of bosonic dimension-eight operators triggered by two dimension-six interactions. In the second scenario I will consider extending the SMEFT to include an axion-like particle and study the RGE effects up to dimension 5. In both cases, some phenomenological consequences will be discussed.
