Discrete Goldstone bosons (2023)
Journal Article
Enguita-Vileta, V., Gavela, B., Houtz, R., & Quilez, P. (2023). Discrete Goldstone bosons. Physical Review D, 107(3), Article 035009. https://doi.org/10.1103/physrevd.107.035009

Exact discrete symmetries, if nonlinearly realized, can reduce the ultraviolet sensitivity of a given theory. The scalars stemming from spontaneous symmetry breaking are massive without breaking the discrete symmetry, and those masses are protected f... Read More about Discrete Goldstone bosons.

Radiative effects in the scalar sector of vector leptoquark models (2022)
Journal Article
Houtz, R., Pagès, J., & Trifinopoulos, S. (2022). Radiative effects in the scalar sector of vector leptoquark models. Journal of High Energy Physics, 2022(8), Article 208. https://doi.org/10.1007/jhep08%282022%29208

Gauge models with massive vector leptoquarks at the TeV scale provide a successful framework for addressing the B-physics anomalies. Among them, the 4321 model has been considered as the low-energy limit of some complete theories of flavor. In this w...

Leptogenesis enabled by dark matter (2022)
Journal Article
Croon, D., Davoudiasl, H., & Houtz, R. (2022). Leptogenesis enabled by dark matter. Physical Review D, 106(3), https://doi.org/10.1103/physrevd.106.035006

We propose that weak scale leptogenesis via ∼10TeV scale right-handed neutrinos could be possible if their couplings had transitory larger values in the early Universe. The requisite lifted parameters can be attained if a light scalar ϕ is displaced... Read More about Leptogenesis enabled by dark matter.

Hamiltonian Truncation Effective Theory (2022)
Journal Article
Cohen, T., Farnsworth, K., Houtz, R., & Luty, M. (2022). Hamiltonian Truncation Effective Theory. SciPost Physics, 13(2), https://doi.org/10.21468/scipostphys.13.2.011

Hamiltonian truncation is a non-perturbative numerical method for calculating observables of a quantum field theory. The starting point for this method is to truncate the interacting Hamiltonian to a finite-dimensional space of states spanned by the... Read More about Hamiltonian Truncation Effective Theory.

Machine learning a manifold (2022)
Journal Article
Craven, S., Croon, D., Cutting, D., & Houtz, R. (2022). Machine learning a manifold. Physical Review D, 105(9), Article 096030. https://doi.org/10.1103/physrevd.105.096030

We propose a simple method to identify a continuous Lie algebra symmetry in a dataset through regression by an artificial neural network. Our proposal takes advantage of the Oðϵ2Þ scaling of the output variable under infinitesimal symmetry transforma... Read More about Machine learning a manifold.

Light dark matter through resonance scanning (2022)
Journal Article
Croon, D., Elor, G., Houtz, R., Murayama, H., & White, G. (2022). Light dark matter through resonance scanning. Physical Review D, 105(6), https://doi.org/10.1103/physrevd.105.l061303

We propose a new out-of-equilibrium production mechanism of light dark matter: resonance scanning. If the dark matter mass evolved in the early Universe, resonant production may have occurred for a wide range of light dark matter masses today. We sho...
