The Hubble Rate Trouble: An Effective Field Theory of Dark Matter
Alvaro S. de Jesus, Nelson Pinto-Neto, Farinaldo S. Queiroz +2
The Hubble constant inferred from the 6-parameter fit to the CMB power spectrum conflicts with the value obtained from direct measurements via type Ia supernova and Cepheids observ…
Present and Future constraints on Secluded Dark Matter in the Galactic Halo with TeV Gamma-ray Observatories
Guilherme Fortes, Farinaldo Queiroz, Clarissa Siqueira +1
The dark matter relic density may be governed by the presence of new mediators that connect the dark matter field with the Standard Model particles. When the dark matter particle m…
Phenomenology of extended multiHiggs doublet models with family symmetry
A. E. Cárcamo Hernández, Catalina Espinoza, Juan Carlos Gómez-Izquierdo +2
We propose extended 3HDM and 4HDM models where the SM gauge symmetry is enlarged by the spontaneously broken group, the preserved and broken cyclic symmetries. Ea…
Phenomenological and cosmological implications of a scotogenic three-loop neutrino mass model
Asmaa Abada, Nicolás Bernal, Antonio E. Cárcamo Hernández +3
We propose a scotogenic model for generating neutrino masses through a three-loop seesaw. It is a minimally extended inert doublet model with a spontaneously broken global symmetry…
Long-lived heavy neutral leptons from mesons in effective field theory
Rebeca Beltrán, Giovanna Cottin, Juan Carlos Helo +3
In the framework of the low-energy effective field theory of the Standard Model extended with heavy neutral leptons (HNLs), we calculate the production rates of HNLs from meson dec…
Long-lived heavy neutral leptons with a displaced shower signature at CMS
Giovanna Cottin, Juan Carlos Helo, Martin Hirsch +3
We study the LHC discovery potential in the search for heavy neutral leptons (HNL) with a new signature: a displaced shower in the CMS muon detector, giving rise to a large cluster…
Dark SU(2) Stueckelberg portal
Valery E. Lyubovitskij, Alexey S. Zhevlakov, Aliaksei Kachanovich +1
We study the non-abelian extension of the Stueckelberg portal, which plays a role of the mediator between the Standard Model (SM) and Dark Sector (DS). This port…
Heavy quark contribution to the electromagnetic properties of the nucleon
Stanley J. Brodsky, Valery E. Lyubovitskij, Ivan Schmidt
Quantum chromodynamics (QCD) predicts the existence of both nonperturbative intrinsic and perturbative extrinsic heavy quark contributions to the fundamental structure of hadrons.…
Searching for light neutralinos with a displaced vertex at the LHC
Giovanna Cottin, Juan Carlos Helo, Fabián Hernández-Pinto +2
We study a bino-like light neutralino () produced at the LHC from the decay of a scalar lepton () through the process $pp\to \tilde e_{L} \to e\tilde χ_1^…
Exclusive doubly charged Higgs boson pair production in collisions at the LHC
Laura Duarte, Victor P. Goncalves, Daniel E. Martins +2
The type II seesaw model predicts the existence of a doubly charged Higgs boson (), which can be produced through the Drell - Yan process and photon -- induced interac…
Probing -parity violation in -meson decays to a baryon and a light neutralino
Claudio O. Dib, Juan Carlos Helo, Valery E. Lyubovitskij +3
We propose a search for meson decays to a baryon plus missing energy at the Belle II experiment to probe supersymmetry with a GeV-scale lightest neutralino and…
Predictions for the Sivers Single-Spin Asymmetry from Holographic QCD
Valery E. Lyubovitskij, Ivan Schmidt, Stanley J. Brodsky
A new approach to nonperturbative QCD, holographic light-front QCD, provides a comprehensive model for hadron dynamics and spectroscopy, incorporating color confinement, a universa…
An inverse seesaw model with perturbed golden ratio mixing
A. E. Cárcamo Hernández, Ivo de Medeiros Varzielas
We propose a theory based on the discrete group which successfully accounts for lepton masses and mixings. In the proposed model, the neutrino masses arise from an inverse se…
Search for Dark Sector by Repurposing the UVX Brazilian Synchrotron
L. Duarte, L. Lin, M. Lindner +6
We propose the first Search for Dark Sector at the Brazilian Synchrotron Light Laboratory, site of Sirius, a fourth-generation storage ring. We show that UVX, Sirius predecessor, c…
Lepton masses and mixings, and muon anomalous magnetic moment in an extended model with type I seesaw mechanism
V. V. Vien, H. N. Long, A. E. Cárcamo Hernández
We propose a model combined with the discrete symmetry which successfully explains the recent sterile - active neutrino data. The smallness of…
How many 1-loop neutrino mass models are there?
Carolina Arbeláez, Ricardo Cepedello, Juan Carlos Helo +2
It is well-known that at tree-level the d=5 Weinberg operator can be generated in exactly three different ways, the famous seesaw models. In this paper we study the related questio…
Implication of the dark axion portal for the EDM of fermions and dark matter probing with NA64, NA64, LDMX, $\mbox{M}^3$, and BaBar
Alexey S. Zhevlakov, Dmitry V. Kirpichnikov, Valery E. Lyubovitskij
The link between ordinary Standard model (SM) photon and both dark photon and axion like particle (ALP) can be introduced through the dark axion portal coupling. Given the dark axi…
Meson masses and decay constants in holographic QCD consistent with ChPT and HQET
Valery E. Lyubovitskij, Ivan Schmidt
We focus on the chiral and heavy quark mass expansion of mesons masses and decay constants. We propose a light-front QCD formalism for the evaluation of these quantities, consisten…
Constraining 3-3-1 Models at the LHC and Future Hadron Colliders
A. Alves, L. Duarte, S. Kovalenko +3
In this work, we derive lower mass bounds on the Z' gauge boson based on the dilepton data from LHC with 13 TeV of center-of-mass energy, and forecast the sensitivity of the High-L…
