We consider the 2 Higgs doublet model (2HDM) and compare two effective field theory
(EFT) approaches to it, according to whether the heavy degrees of freedom are integrated …

In recent years, theoretical and phenomenological studies with effective field theories have
become a trending and prolific line of research in the field of high-energy physics. In order to …

We present the universal one-loop effective action up to dimension eight after integrating out
heavy fermion (s) using the Heat-Kernel method. We have discussed how the Dirac operator …

The program AutoEFT is described. It allows one to generate Effective Field Theories (EFTs)
from a given set of fields and symmetries. Allowed fields include scalars, spinors, gauge …

A bstract The ongoing Effective Field Theory (EFT) program at the LHC and elsewhere is
motivated by streamlining the connection between experimental data and UV-complete …

Linear Standard Model (SM) extensions, defined as new particles that can couple linearly to
SM fields, form a motivated and finite set of simplified models for exploring phenomenology …

We propose a heat-kernel-based method to compute one-loop effective action up to any
mass-dimension with arbitrary numbers of non-degenerate scalars and fermions. We …

We present a systematic method for determining the two-loop effective Lagrangian resulting
from integrating out a set of heavy particles in an ultraviolet scalar theory. We prove that the …

A bstract The effective field theory approach parameterizes the low energy behaviors of all
possible ultraviolet (UV) theories in a systematic way. One of the most important tasks is thus …

The two-Higgs doublet model (2HDM) is a well understood alternative to the Standard
Model of particle physics. If the new particles included in the 2HDM are at an energy scale …
