New fermions in the light of the
J. C. Criado, A. Djouadi, N. Koivunen +3
The very precise measurement of the anomalous magnetic moment of the muon, recently released by the Muon g-2 experiment at Fermilab, can serve to set stringent constraints on new p…
Simulating magnetic antiskyrmions on the lattice
Juan C. Criado, Peter D. Hatton, Sebastian Schenk +2
Magnetic skyrmions are topologically protected spin structures that naturally emerge in magnetic materials. While a vast amount of effort has gone into the study of their propertie…
Electroweak Skyrmions in the HEFT
Juan Carlos Criado, Valentin V. Khoze, Michael Spannowsky
We study the existence of skyrmions in the presence of all the electroweak degrees of freedom, including a dynamical Higgs boson, with the electroweak symmetry being non-linearly r…
An effective field theory of the Delta-resonance
Juan Carlos Criado, Abdelhak Djouadi, Niko Koivunen +3
We present an effective field theory of the -resonance as an interacting Weinberg's field in the multi-spinor formalism. We derive its interactions with…
Confronting spin-3/2 and other new fermions with the muon g-2 measurement
Juan C. Criado, Abdelhak Djouadi, Niko Koivunen +3
The new measurement of the muon's anomalous magnetic moment released by the Muon g-2 experiment at Fermilab sets strong constraints on the properties of many new particles. Using a…
A complete effective field theory for dark matter
Juan Carlos Criado, Abdelhak Djouadi, Manuel Perez-Victoria +1
We present an effective field theory describing the relevant interactions of the Standard Model with an electrically neutral particle that can account for the dark matter in the Un…
Elvet -- a neural network-based differential equation and variational problem solver
Jack Y. Araz, Juan Carlos Criado, Michael Spannowsky
We present Elvet, a Python package for solving differential equations and variational problems using machine learning methods. Elvet can deal with any system of coupled ordinary or…
Higher-spin particles at high-energy colliders
Juan Carlos Criado, Abdelhak Djouadi, Niko Koivunen +2
Using an effective field theory approach for higher-spin fields, we derive the interactions of colour singlet and electrically neutral particles with a spin higher than unity, conc…
