The art of simulating the early Universe. Part II. Non-canonical cases & gravitational waves
Jorge Baeza-Ballesteros, Daniel G. Figueroa, Adrien Florio +7
We present a discussion on lattice techniques for the simulation of non-canonical field theory circumstances, complementing our previous monograph (arXiv:2006.15122) on canonical c…

Hadron interactions and cosmic strings from lattice simulations
Jorge Baeza-Ballesteros
This doctoral thesis focuses on the application of lattice techniques to study two separate topics: hadron interactions within quantum chromodynamics (QCD), and the emission of par…
Gravitational wave and particle emission from a cosmic string loop: local case
Jorge Baeza-Ballesteros, Edmund J. Copeland, Daniel G. Figueroa +1
Using lattice field simulations of the Abelian-Higgs model, we characterize the simultaneous emission of (scalar and gauge) particles and gravitational waves (GWs) by local string…
The three-pion -matrix at NLO in ChPT
Jorge Baeza-Ballesteros, Johan Bijnens, Tomáš Husek +3

Towards a realistic setup for a dynamical measurement of deviations from Newton's law: the impact of air viscosity
Jorge Baeza-Ballesteros, Andrea Donini, Gabriel Molina-Terriza +2
A novel experimental setup to measure deviations from the distance dependence of Newtonian gravity was proposed in arXiv:1609.05654. The underlying theoretical idea was to…
Three-pion scattering: From the chiral Lagrangian to the lattice
Jorge Baeza-Ballesteros, Johan Bijnens, Tomáš Husek +3
In recent years, detailed studies of three-pion systems have become possible in lattice QCD. This has in turn led to interest in 3-to-3 scattering of pions in the chiral perturbati…
Gravitational Wave Emission from a Cosmic String Loop, I: Global Case
Jorge Baeza-Ballesteros, Edmund J. Copeland, Daniel G. Figueroa +1
We study the simultaneous decay of global string loops into scalar particles (massless and massive modes) and gravitational waves (GWs). Using field theory simulations in flat spac…
