Minimal Scale-Invariant Dark Matter
Alexander Belyaev, Roman Pasechnik, Rishav Roshan +1
We study the minimal classically scale-invariant extension of the Standard Model, containing a single -stabilised real scalar singlet whose mass is not an independent…
Vector Dark Matter in the Fundamental Representation of : Sommerfeld Enhancement and Indirect Detection
Sebastian Acevedo, Sebastián Acevedo-Espinoza, Alfonso R. Zerwekh +1
In this work, we study an extension of the Standard Model that includes a new massive vector field in the fundamental representation of . The neutral component of this f…
Phenomenology of an Extended Higgs Doublet Model with Family Symmetry
A. E. Cárcamo Hernández, Daniel Salinas-Arizmendi, Jonatan Vignatti +1
In order to explain the mass hierarchy and mixing pattern in the leptonic sector, we explore an extension of the Standard Model whose scalar sector includes one active and two iner…
Vector Dark Matter from the 5-Dimensional Representation of
Patricio Escalona, Sebastián Acevedo, Paulo Areyuna +3
The introduction of electroweak multiplets that transform under any representation of the standard gauge group suggests the existence of electrically neutral stable parti…
A common framework for fermion mass hierarchy, leptogenesis and dark matter
Carolina Arbeláez, A. E. Cárcamo Hernández, Claudio Dib +3
In this work, we explore an extension of the Standard Model designed to elucidate the fermion mass hierarchy, account for the dark matter relic abundance, and explain the observed…
Mono-Higgs and Mono- Production in the Minimal Vector Dark Matter Model
Gonzalo BenÃtez-Irarrázabal, Alfonso R. Zerwekh
The Minimal Vector Dark Matter is a viable realization of the minimal dark matter paradigm. It extends the Standard Model by the inclusion of a vector matter field in the adjoint r…
