A Near-Conformal Composite Higgs Model
Thomas Appelquist, James Ingoldby, Maurizio Piai
We analyze a composite Higgs model based on the confining gauge theory with Dirac fermions in the fundamental representation. This gauge theory has been studied o…
EFT anomalous dimensions from the S-matrix
Joan Elias Miró, James Ingoldby, Marc Riembau
We use the on-shell S-matrix and form factors to compute anomalous dimensions of higher dimension operators in the Standard Model Effective Field Theory. We find that in many insta…
The Dilaton Potential and Lattice Data
Thomas Appelquist, James Ingoldby, Maurizio Piai
We study an effective field theory (EFT) describing the interaction of an approximate dilaton with a set of pseudo-Nambu-Goldstone bosons (pNGBs). The EFT is inspired by, and emplo…
Linear Sigma EFT for Nearly Conformal Gauge Theories
T. Appelquist, R. C. Brower, G. T. Fleming +11
We construct a generalized linear sigma model as an effective field theory (EFT) to describe nearly conformal gauge theories at low energies. The work is motivated by recent lattic…
