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…
First survey of centimeter-scale AC-LGAD strip sensors with a 120 GeV proton beam
Christopher Madrid, Ryan Heller, Claudio San Martín +12
We present the first beam test results with centimeter-scale AC-LGAD strip sensors, using the Fermilab Test Beam Facility and sensors manufactured by the Brookhaven National Labora…
Model reduction for molecular diffusion in nanoporous media
Gastón González, Rubén A. Fritz, Yamil J. Colón +1
Porous materials are widely used for applications in gas storage and separation. The diffusive properties of a variety of gases in porous media can be modeled using molecular dynam…
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…
Model Independent Approach of the JUNO B Solar Neutrino Program
JUNO Collaboration, Jie Zhao, Baobiao Yue +593
The physics potential of detecting B solar neutrinos will be exploited at the Jiangmen Underground Neutrino Observatory (JUNO), in a model independent manner by using three dis…
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.…
Open quantum dynamics of strongly coupled oscillators with multi-configuration time-dependent Hartree propagation and Markovian quantum jumps
Johan F. Triana, Felipe Herrera
Modeling the non-equilibrium dissipative dynamics of strongly interacting quantized degrees of freedom is a fundamental problem in several branches of physics and chemistry. We imp…
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…
Search for a New B-L Z' Gauge Boson with the NA64 Experiment at CERN
Yu. M. Andreev, D. Banerjee, B. Banto-Oberhauser +55
A search for a new gauge boson associated with (un)broken B-L symmetry in the keV-GeV mass range is carried out for the first time using the missing-energy technique in the NA…
A tentative 1000 km s offset between the [CII] 158 m and Ly line emission in a star-forming galaxy at
R. Baier-Soto, R. Herrera-Camus, N. M. Förster Schreiber +4
GN-108036 is a star-forming galaxy at , and one of the most distant known sources in the Northern hemisphere. Based on observations from the NOrthern Extended Millimeter Ar…
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…
