Discovering heavy U(1)-gauged Higgs bosons at the HL-LHC
Daniel A. Camargo, Michael Klasen, Sybrand Zeinstra
We determine the discovery potential of the Large Hadron Collider (LHC) at 13 TeV center-of-mass energy for a heavy scalar resonance in the dilepton channel. In particular, we cons…
A Two Higgs Doublet Model for Dark Matter and Neutrino Masses
Daniel A. Camargo, Miguel D. Campos, Téssio B. de Melo +1
Motivated by the interesting features of Two Higgs Doublet Models (2HDM) we present a 2HDM extension where the stability of dark matter, neutrino masses and the absence of flavor c…
Detecting Dark Matter with Neutron Star Spectroscopy
Daniel A. Camargo, Farinaldo S. Queiroz, Riccardo Sturani
The presence of dark matter has been ascertained through a wealth of astrophysical and cosmological phenomena and its nature is a central puzzle in modern science. Elementary parti…
Neutrino Masses in a Two Higgs Doublet Model with a U(1) Gauge Symmetry
Daniel A. Camargo, Alex G. Dias, Tessio B. de Melo +1
General Two Higgs Doublet Models (2HDM) are popular Standard Model extensions but feature flavor changing interactions and lack neutrino masses. We discuss a 2HDM where neutrino ma…
Asymmetric Dark Matter, Inflation and Leptogenesis from B-L Symmetry Breaking
P. V. Dong, D. T. Huong, Daniel A. Camargo +2
We propose a unified setup for dark matter, inflation and baryon asymmetry generation through the neutrino mass seesaw mechanism. Our scenario emerges naturally from an extended ga…
Collider Bounds on 2-Higgs Doublet Models with Gauge Symmetries
Daniel A. Camargo, Luigi Delle Rose, Stefano Moretti +1
2-Higgs Doublet Models (2HDMs) typically need to invoke an ad-hoc discrete symmetry to avoid severe flavor bounds and in addition feature massless neutrinos, thus falling short of…
XENON1T Takes a Razor to a Dark -Inspired Model
Daniel A. Camargo, Yann Mambrini, Farinaldo S. Queiroz
Motivated by the recent result of XENON1T collaboration with full exposure, 279 life days, that sets the most stringent limit on the spin-independent dark matter-nucleon scattering…
Dark Matter in Anomaly-Free Gauge Extensions
Martin Bauer, Sascha Diefenbacher, Tilman Plehn +2
A consistent model for vector mediators to dark matter needs to be anomaly-free and include a scalar mode from mass generation. For the leading U(1) extensions we review the struct…
Collider and Dark Matter Searches in the Inert Doublet Model from Peccei-Quinn Symmetry
Alexandre Alves, Daniel A. Camargo, Alex G. Dias +3
Weakly Interacting Massive Particles (WIMPs) and axions are arguably the most compelling dark matter candidates in the literature. Could they coexist as dark matter particles? More…
Heavy Higgs Coupled to Vector-like Quarks: Strong CP Problem and Search Prospects at the 14 TeV LHC
Alexandre Alves, D. A. Camargo, Alex G. Dias
Motivated by a solution to the strong CP problem we propose a model where a new heavy neutral CP-even Higgs boson couples to vector-like quarks enhancing its production cross secti…
A Model with New Signatures of Exotic Chiral Fermions Coupling with Scalar Leptoquarks
D. A. Camargo
In this paper, the possibility to have new physics is considered at the scale of the electroweak symmetry breaking (EWSB) in a completely new framework. A new non-standard minimal…
A Model with Chiral Quarks of Electric Charges -4/3 and 5/3
Alexandre Alves, E. Ramirez Barreto, D. A. Camargo +1
We present a new model based on the SU(3)xSU(2)xU(1) symmetry, in which there is a new consistent set of chiral fermion fields that renders the model free from anomalies. The new f…
