Reassessing CP Violation in the C2HDM with Machine Learning
Rafael Boto, Karim Elyaouti, Duarte Fontes +5
We provide a study of the parameter space of the complex 2-Higgs Doublet Model (C2HDM), focusing on signs of large CP-violating couplings of the 125 GeV Higgs boson with the fermio…
Solenoids in automorphism groups of evolution algebras
Yolanda Cabrera Casado, Maria Inez Cardoso Gonçalves, Daniel Gonçalves +3
Let A be an evolution algebra (possibly infinite-dimensional) equipped with a fixed natural basis B, and let E be the associated graph defined by Elduque and Labra. We describe the…
Squares and associative representations of two dimensional evolution algebras
Maria Inez Cardoso Gonçalves, Daniel Gonçalves, Dolores Martín Barquero +2
We associate an square to any two dimensional evolution algebra. This geometric object is uniquely determined, does not depend on the basis and describes the structure and the beha…
Infinite Symmetric Matrices over Z_2 and the Lights Out Problem
Daniel Gonçalves, Maria Inez Cardoso Gonçalves
We show, using a hybrid analysis/linear algebra argument, that the diagonal vector of an infinite symmetric matrix over is contained in the range of the matrix. We…
