Catalog of electroweak scalar manifolds
Juan Carlos Criado
The local structure of the Higgs sector around the vacuum does not uniquely determine its global properties. Most of the current experimental data provides only local information,…
Potential Blind Directions at TeraZ
Mikael Chala, Juan Carlos Criado, Michael Spannowsky
The next generation of high-luminosity electron-positron colliders, such as FCC-ee and CEPC operating at the pole (TeraZ), is expected to deliver unprecedented precision in ele…
Field Redefinitions in Classical Field Theory with some Quantum Perspectives
Juan Carlos Criado, Joerg Jaeckel, Michael Spannowsky
In quantum field theories, field redefinitions are often employed to remove redundant operators in the Lagrangian, making calculations simpler and physics more evident. This techni…
Higher-order corrections to phase-transition parameters in dimensional reduction
Mikael Chala, Juan Carlos Criado, Luis Gil +1
The dynamics of phase transitions (PT) in quantum field theories at finite temperature is most accurately described within the framework of dimensional reduction. In this framework…
Iteration on the Higgs-portal for vector Dark Matter and its effective field theory description
Giorgio Arcadi, Juan Carlos Criado, Abdelhak Djouadi
We reanalyze the effective field theory (EFT) approach for the scenario in which the particles that account for the dark matter (DM) in the universe are vector states that interact…
Walls, bubbles and doom -- the cosmology of HEFT
Rodrigo Alonso, Juan Carlos Criado, Rachel Houtz +1
As experiment charts new territory at the electroweak scale, the enterprise to characterise all possible theories becomes all the more necessary. In the absence of new particles, t…
Training Neural Networks with Universal Adiabatic Quantum Computing

Juan Carlos Criado, Peter D. Hatton, Álvaro Lanza +2
Chiral magnets with Dzyaloshinskii-Moriya interactions feature a rich phase diagram with a variety of thermodynamical phases. These include helical and conical spin arrangements an…
LHC EFT WG Note: Precision matching of microscopic physics to the Standard Model Effective Field Theory (SMEFT)
Sally Dawson, Admir Greljo, Kristin Lohwasser +16
This note gives an overview of the tools for the precision matching of ultraviolet theories to the Standard Model effective field theory (SMEFT) at the tree level and one loop. Sev…
QFitter -- A Quantum Fitting Framework Applied to Effective Field Theories
Juan Carlos Criado, Roman Kogler, Michael Spannowsky
The use of experimental data to constrain the values of the Wilson coefficients of an Effective Field Theory (EFT) involves minimising a function that may contain local minim…
Identifying magnetic antiskyrmions while they form with convolutional neural networks
Jack Y. Araz, Juan Carlos Criado, Michael Spannowsky
Chiral magnets have attracted a large amount of research interest in recent years because they support a variety of topological defects, such as skyrmions and bimerons, and allow f…
Qade: Solving Differential Equations on Quantum Annealers
Juan Carlos Criado, Michael Spannowsky
We present a general method, called Qade, for solving differential equations using a quantum annealer. The solution is obtained as a linear combination of a set of basis functions.…
