DESCRIPTION:Speakers: Adrián Moreno Sánchez (Universidad de Granada)\nEf
 fective field theories have been gathering increasing attention in recent 
 years. Within this field\, the matching process is a key question for conn
 ecting this formalism with precise UV theories beyond the Standard Model. 
 It is precisely here where functional methods have emerged as very efficie
 nt tools\, especially for automating computations.\n\nSo far\, this method
  has been applied up to one loop. I present a systematic procedure for goi
 ng beyond\, considering both fermionic and bosonic degrees of freedom. I w
 ill demonstrate how the inclusion of gauge bosons requires a new approach 
 to the problem that was not necessary in the one-loop case. It will rely o
 n the introduction of the Wilson line to obtain a covariant expansion.\n\n
 Additionally\, this method will be exemplifyed with the matching of QED to
  the Euler-Heisenberg Lagrangian\n\nhttps://indico.ific.uv.es/event/7664/c
