Renormalization of general Effective Field Theories: Renormalization of fermionic operators
Renato M. Fonseca, Pablo Olgoso, José Santiago
Renormalization group equations play a central role in effective field theories, both maintaining perturbative control and allowing one to determine the correct low-energy phenomen…

Renormalization of general Effective Field Theories: Formalism and renormalization of bosonic operators
Renato M. Fonseca, Pablo Olgoso, José Santiago
We describe the most general local, Lorentz-invariant, effective field theory of scalars, fermions and gauge bosons up to mass dimension 6. We first obtain both a Green and a physi…

Efficient on-shell matching
Mikael Chala, Javier López Miras, José Santiago +1
We propose an efficient method to perform on-shell matching calculations in effective field theories. The standard off-shell approach to matching requires the use of a Green's basi…
