Dilaton Effective Field Theory [PDF]
Universe, 2022 We review and extend recent studies of dilaton effective field theory (dEFT) that provide a framework for the description of the Higgs boson as a composite structure.

Effective field theory for chaotic CFTs [PDF]
Journal of High Energy Physics, 2018 We derive an effective field theory for general chaotic two-dimensional conformal field theories with a large central charge. The theory is a specific and calculable instance of a more general framework recently proposed in [1].

On the development of effective field theory [PDF]
The European Physical Journal H, 2021 Editor’s note: One of the most important developments in theoretical particle physics at the end of the 20th century and beginning of the twenty-first century has been the development of effective field theories (EFTs). Pursuing an effective field theory

Effective field theory for leptoquarks
Journal of High Energy Physics, 2023 Leptoquarks enter in several extensions of the Standard Model as possible solutions to a number of observed anomalies. We work within the soft-collinear effective theory framework to present a detailed analysis of the decay rates of the three leptoquarks

Effective Field Theory of Random Quantum Circuits [PDF]
Entropy, 2022 Quantum circuits have been widely used as a platform to simulate generic quantum many-body systems. In particular, random quantum circuits provide a means to probe universal features of many-body quantum chaos and ergodicity.

Effective Field Theory of 3He [PDF]
Few-Body Systems, 2010 3He and the triton are studied as three-body bound states in the effective field theory without pions. We study 3He using the set of integral equations developed by Kok et al. which includes the full off-shell T-matrix for the Coulomb interaction between the protons.

The geometric Standard Model Effective Field Theory [PDF]
Journal of High Energy Physics, 2020 We develop the geometric formulation of the Standard Model Effective Field Theory (SMEFT). Using this approach we derive all-orders results in the 2 H † H / Λ $$ \sqrt{2\left\langle {H}^{\dagger }H\right\rangle }/\Lambda $$ expansion relevant for studies

Effective Field Theories [PDF]
, 1995 These lectures introduce some of the basic notions of effective field theories, as used in particle physics. The topics discussed are the $ S=1$ and $ S =2$ weak interactions, and chiral perturbation theory as applied to mesons, baryons, and hadrons containing heavy quarks.
