Renormalon subtraction in OPE by dual space approach: nonlinear sigma model and QCD
Journal of High Energy Physics, 2023 It is becoming more important to subtract renormalons efficiently from perturbative calculations, in order to achieve high precision QCD calculations. We propose a new framework “Dual Space Approach” for renormalon separation, which enables subtraction ...

Bell violation in 2 → 2 scattering in photon, gluon and graviton EFTs
Journal of High Energy Physics, 2023 In this paper, we explore Bell inequality violation for 2 → 2 scattering in Effective Field Theories (EFTs) of photons, gluons, and gravitons. Using the CGLMP Bell parameter (I 2), we show that, starting from an appropriate initial non-product state, the

Amplitude/operator basis in chiral perturbation theory
Journal of High Energy Physics, 2023 We establish a systematic construction of the on-shell amplitude/operator basis for Chiral Perturbation Theory (ChPT) in D = 4 spacetime dimensions and with an arbitrary number of flavors N f .

QCD phase transitions in an effective field theory [PDF]
Nuclear Physics B, 1990 Abstract We analyze the transitions between hadronic and quark-gluon phases of QCD using an effective low-energy lagrangian for chiral and scale invariance, which embodies quark and gluon condensation. We argue that the quark condensation and deconfinement transitions take place at the same temperature, T q , and that gluon condensation and ...

Journal of High Energy Physics, 2022 In large-momentum effective theory (LaMET), the transverse-momentum-dependent (TMD) light-front wave functions and soft functions can be extracted from the simulation of a four-quark form factor and equal-time correlation functions.

Deconfinement critical point of heavy quark effective lattice theories [PDF]
, 2022 Effective three-dimensional Polyakov loop theories derived from QCD by strong coupling and hopping expansions are valid for heavy quarks and can also be applied to finite chemical potential μ, due to their considerably milder sign problem.

Systematic parametrization of the leading B-meson light-cone distribution amplitude
Journal of High Energy Physics, 2022 We propose a parametrization of the leading B-meson light-cone distribution amplitude (LCDA) in heavy-quark effective theory (HQET). In position space, it uses a conformal transformation that yields a systematic Taylor expansion and an integral bound ...

Effective Field Theories [PDF]
, 2020 This paper represents a pedagogical introduction to low-energy effective field theories. In some of them, heavy particles are “integrated out” (a typical example—the Heisenberg–Euler EFT); in some, heavy particles remain but some ...

Effective field theory for the crystalline colour superconductive phase of QCD [PDF]
Physics Letters B, 2001 We present an effective field theory for high density, low temperature QCD in the crystalline colour superconductive phase (LOFF phase). This interesting phase of QCD is characterized by a gap parameter with a crystalline pattern, breaking traslational and rotational invariance, and could have astrophysical applications.
