Fermion mass hierarchy and flavor signals from a dihedral symmetry within a 2HDM-Tx with four-zero textures
M. A. Arroyo-Ureña, E. Díaz, J. L. Díaz-Cruz +1
We propose an extended Texturized Two-Higgs Doublet Model (2HDM-Tx) where a discrete symmetry predicts a four-zero texture in the fermion mass matrices. In contrast to the st…
Cosmic-ray antiproton excess from annihilating tensor dark matter
H. Hernández-Arellano, M. Napsuciale, S. Rodríguez +1
In this paper we calculate the antiproton production in the annihilation of tensor dark matter and explore the possibility that the excess of antiprotons in the range $E_{K}=10-20…
Kinetic mixing, custodial symmetry, , interactions and production in hadron colliders
M. Napsuciale, S. Rodriguez, H. Hernandez-Arellano
In this work we study the interactions of the and generated by kinetic mixing in a class of theories for physics beyond the standard model motivated by the dark ma…
Kinetic mixing, custodial symmetry and a lower bound on the dark mass
M. Napsuciale, S. Rodríguez, H. Hernández-Arellano
In this work we consider the extension of the standard model by dark fields with an Abelian spontaneously broken gauge symmetry in a hidden dark matter scenario. Conside…
Spin-one dark matter and gamma ray signals from the galactic center
H. Hernandez-Arellano, M. Napsuciale, S. Rodriguez
In this work we study the possibility that the gamma ray excess (GRE) at the Milky Way galactic center come from the annihilation of dark matter with a space-tim…
Spin portal to dark matter
H. Hernández-Arellano, M. Napsuciale, S. Rodríguez
In this work we study the possibility that dark matter fields transform in the representation of the Homogeneous Lorentz Group. In an effective theory approach,…
