A note on analytic continuation to Minkowski space relevant for decay-model phenomenology
Alexandre Salas-Bernárdez, Juan Ferrera, Felipe J. Llanes-Estrada
We discuss some aspects of the uniqueness of analytically continuing Euclidean Green functions obtained by means of the Dyson-Schwinger equations (DSEs) and constrained by lattice…
The left-cut for partial waves in terms of physical amplitudes
Alexandre Salas-Bernárdez
We derive a novel representation of the partial wave amplitude over the left-hand cut for scattering. We express the left-hand cut of arbitrary isospin and angular moment…
Analytical Quantum Field methods in Particle Physics
Alexandre Salas-Bernárdez
In this thesis we deal with different aspects of quantum field theory, particularly in non-perturbative but also perturbative regimes, applied to the intellectual construction that…
Detectable Gravitational Wave Signals from Inflationary Preheating
Yanou Cui, Evangelos I. Sfakianakis
We consider gravitational wave (GW) production during preheating in hybrid inflation models where an axion-like waterfall field couples to Abelian gauge fields. Based on a linear a…
Assessment of systematic theory uncertainties in IAM unitarization
Juan Escudero-Pedrosa, Felipe J. Llanes-Estrada, José Antonio Oller +1
Effective Field Theories (EFTs) for Goldstone Boson scattering at a low order allow the computation of near--threshold observables in terms of a few coefficients arranged by a coun…
Systematizing and addressing theory uncertainties of unitarization with the Inverse Amplitude Method
Alexandre Salas-Bernárdez, Felipe J. Llanes-Estrada, Juan Escudero-Pedrosa +1
Effective Field Theories (EFTs) constructed as derivative expansions in powers of momentum, in the spirit of Chiral Perturbation Theory (ChPT), are a controllable approximation to…
