ALPs effective field theory and collider signatures [PDF]

European Physical Journal C: Particles and Fields, 2017
We study the leading effective interactions between the Standard Model fields and a generic singlet CP-odd (pseudo-) Goldstone boson. Two possible frameworks for electroweak symmetry breaking are considered: linear and non-linear.

Effective Field Theory for Inflation [PDF]

Physical Review D, 2008
The methods of effective field theory are used to study generic theories of inflation with a single inflaton field. For scalar modes, the leading corrections to the ${\cal R}$ correlation function are found to be purely of the $k$-inflation type.

The Effective Field Theory of Inflation [PDF]

Journal of High Energy Physics, 2008
We study the effective field theory of inflation, i.e. the most general theory describing the fluctuations around a quasi de Sitter background, in the case of single field models. The scalar mode can be eaten by the metric by going to unitary gauge.

D-brane effective field theory from string field theory [PDF]

, 2000
Open string field theory is considered as a tool for deriving the effective action for the massless or tachyonic fields living on D-branes. Some simple calculations are performed in open bosonic string field theory which validate this approach. The level

A Lagrangian effective field theory [PDF]

Journal of Cosmology and Astroparticle Physics, 2015
We have continued the development of Lagrangian, cosmological perturbation theory for the low-order correlators of the matter density field. We provide a new route to understanding how the effective field theory (EFT) of large-scale structure can be ...

The Hypertriton in Effective Field Theory [PDF]

Nuclear Physics A, 2001
Doublet Lambda d scattering and the hypertriton are studied in the framework of an effective field theory for large scattering lengths. As in the triton case, consistent renormalization requires a one-parameter three-body force at leading order whose ...

Effective field theory for magnetic compactifications [PDF]

Journal of High Energy Physics, 2017
Magnetic flux plays an important role in compactifications of field and string theories in two ways, it generates a multiplicity of chiral fermion zero modes and it can break supersymmetry. We derive the complete four-dimensional effective action for N $$

Effective field theory and in-in correlators

Journal of High Energy Physics
The predictions of inflation are usually defined in terms of equal time in-in correlation functions in an accelerating cosmological background. These same observables exist for quantum field theory in other spacetimes, including flat space. In this paper,

Effective Field Theory of Cosmological Perturbations [PDF]

Classical and Quantum Gravity, 2013
The effective field theory of cosmological perturbations stems from considering a cosmological background solution as a state displaying spontaneous breaking of time translations and (adiabatic) perturbations as the related Nambu-Goldstone modes.

Extended effective field theory of inflation [PDF]

Journal of High Energy Physics, 2018
We present a general framework where the effective field theory of single field inflation is extended by the inclusion of operators with mass dimension 3 and 4 in the unitary gauge.
