Regge behavior in effective field theory
, 2014 We derive the Regge behavior for the forward scattering amplitude in scalar field theory using the method of regions. We find that the leading Regge behavior to all orders can be obtained.

Cosmic Microwave Background from Effective Field Theory
Universe, 2019 In this work, we study the key role of generic Effective Field Theory (EFT) framework to quantify the correlation functions in a quasi de Sitter background for an arbitrary initial choice of the quantum vacuum state. We perform the computation in unitary

Nucleon-Nucleon effective field theory with dibaryon fields [PDF]
arXiv, 2009 We report on a calculation of the nucleon-nucleon scattering amplitudes in the $^1S_0$ and $^3S_1$-$^3D_1$ channels at next-to-next to leading order using a recently proposed non-relativistic chiral effective theory, which includes dibaryon field as fundamental degrees of freedom.

X(3872) in effective field theory
, 2006 We consider the implications from the possibility that the recently observed state X(3872) is a meson-antimeson molecule. We write an effective Lagrangian consistent with the heavy-quark and chiral symmetries needed to describe X(3872) and study its ...

Effective Field Theories [PDF]
, 2013 This chapter reviews effective field theory (EFT) techniques, focusing on the intertheoretic relations between low-energy effective theories and their high-energy counterparts. It discusses how EFT can be interpreted and describes the steps in the construction of an EFT in the top-down and bottom-up approaches.

Why Renormalizable NonCommutative Quantum Field Theories? [PDF]
arXiv, 2007 We complete our previous recent review on noncommutative field theory, discussing in particular the constructive aproach to the Grosse-Wulkenhaar theory. We also suggest that by gluing together many Grosse-Wulkenhaar theories at high energy one can obtain an effective commutative field theory at lower energy.
