Tri-hypercharge versus tri-darkcharge
Duong Van Loi, A. E. Cárcamo Hernández, Van Que Tran +1
We propose a minimal, ultraviolet-complete, and renormalizable extension of the Standard Model, in which the three generations of ordinary fermions are distinguished by family-depe…
Updated BBN Bounds on Hadronic Injection in the Early Universe: The Gravitino Problem
Lucia Angel, Giorgio Arcadi, Matheus M. A. Paixão +1
Late-decaying particles naturally arise in many extensions of the Standard Model, directly impacting key cosmological processes in the early universe, such as Big Bang Nucleosynthe…
Fermion masses and mixings and charged lepton flavor violation in a 3-3-1 model with inverse seesaw
A. E. Cárcamo Hernández, D. T. Huong, H. N. Long +1
We present a extension of the 3-3-1 gauge model supplemented by an flavor symmetry and cyclic discrete symmetries, including , , , , and .…
The Hubble Tension: Relativistic Dark Matter Production from Long-lived Particles
Alvaro S. de Jesus, Matheus M. A. Paixão, Dêivid R. da Silva +2
The tension between direct measurements of the Hubble constant and those stemming from Cosmic Microwave Background probes has triggered a multitude of studies. The connection betwe…
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…
Flavor phenomenology of an extended 2HDM with inverse seesaw mechanism
N. T. Duy, D. T. Huong, A. E. Carcamo Hernandez
We perform a detailed and comprehensive study of several flavor physics observables in both lepton and quark sectors within the framework of an extended 2HDM theory where the inver…
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…
Predictive linear seesaw model with family symmetry
A. E. Cárcamo Hernández, Ivo de Medeiros Varzielas, Juan Marchant González
We consider a model that accounts for the smallness of neutrino masses through the linear seesaw mechanism and employs a family symmetry to address the flavour problem. The…
Constraining Gamma-ray Lines from Dark Matter Annihilation using Fermi-LAT and H.E.S.S. data
Lucia Angel, Guillermo Gambini, Leticia Guedes +2
Using 14 years of Fermi-LAT data and 10 years of H.E.S.S. observations in the direction of the galactic center, we derive limits on gamma-ray lines originated from dark matter anni…
Updated Big Bang Nucleosynthesis Bounds on Long-lived Particles from Dark Sectors
J. R. Alves, L. Angel, L. Guedes +5
As electromagnetic showers may alter the abundance of Helium, Lithium, and Deuterium, we can place severe constraints on the lifetime and amount of electromagnetic energy injected…
Global analysis and LHC study of a vector-like extension of the Standard Model with extra scalars
A. E. Cárcamo Hernández, Kamila Kowalska, Huchan Lee +1
We perform a global analysis of a vector-like extension of the Standard Model, which also features additional doublet and singlet scalars. The usual Yukawa interactions are forbidd…

Mikhail A. Ivanov, Valery E. Lyubovitskij, Zhomart Tyulemissov
The nonleptonic decay with is systematically studied in the framework of the covariant confined quark model with accounting for both short and long dis…
Probing a Dark Sector with Collider Physics, Direct Detection, and Gravitational Waves
Giorgio Arcadi, Glauber C. Dorsch, Jacinto P. Neto +2
We assess the complementarity between colliders, direct detection searches, and gravitational wave interferometry in probing a scenario of dark matter in the early universe. The mo…
Bulk-to-boundary propagators with arbitrary total angular momentum in soft-wall AdS/QCD
Valery E. Lyubovitskij, Ivan Schmidt
We derive the equations of motion for the bulk-to-boundary propagators of the anti-de Sitter (AdS) boson and fermion fields with arbitrary total angular momentum , in a soft-wal…
Dark Matter from a Radiative Inverse Seesaw Majoron Model
Cesar Bonilla, A. E. Cárcamo Hernández, Bastián Díaz Sáez +2
We propose a Majoron-like extension of the Standard Model with an extra global -symmetry where neutrino masses are generated through an inverse seesaw mechanism at the 1-lo…
Phenomenological aspects of the fermion and scalar sectors of a flavored 3-3-1 model
A. E. Cárcamo Hernández, Juan Marchant González, M. L. Mora-Urrutia +1
We proposed a viable and predictive model based on the gauge symmetry, supplemented by the global symmetry, the family symm…
Fermion mass hierarchy in an extended left-right symmetric model
Cesar Bonilla, A. E. Cárcamo Hernández, Sergey Kovalenko +3
We present a Left-Right symmetric model that provides an explanation for the mass hierarchy of the charged fermions within the framework of the Standard Model. This explanation is…
Linear seesaw mechanism from dark sector
A. E. Cárcamo Hernández, Vishnudath K. N., José W. F. Valle
We propose a minimal model where a dark sector seeds neutrino mass generation radiatively within the linear seesaw mechanism. Neutrino masses are calculable, since tree-level contr…
Reinterpretation of searches for long-lived particles from meson decays
Rebeca Beltrán, Giovanna Cottin, Martin Hirsch +2
Many models beyond the Standard Model predict light and feebly interacting particles that are often long-lived. These long-lived particles (LLPs) in many cases can be produced from…
The Hubble Rate Trouble: An Effective Field Theory of Dark Matter
Alvaro S. de Jesus, Nelson Pinto-Neto, Farinaldo S. Queiroz +2
