MeV dark matter decay forecasts for the COSI mission
Robin Anthony-Petersen, Orion Ning, Yu Watanabe +21
The decay of dark matter (DM) is a generic prediction of many particle physics models, producing distinctive monochromatic signatures in environments such as the Galactic halo. Sea…
Sub-MeV gamma-ray lines from an endothermic interpretation of the LZ recoil candidate
Maíra Dutra, Jacinto P. Neto, Clarissa Siqueira
Endothermic upscattering of heavy dark matter offers a compelling interpretation of the high-energy nuclear-recoil candidate recently reported by LUX-ZEPLIN (LZ), with a characteri…
Constraining light dark matter in vector-scalar portals with COSI and AMEGO-X
Maíra Dutra, Clarissa Siqueira, Tonia M. Venters
Detecting gamma-ray signals that could be due to dark matter (DM) particles would give us invaluable information about the nature of DM. In particular, gamma-ray lines could provid…
The Waning of the WIMP: Endgame?
Giorgio Arcadi, David Cabo-Almeida, Maíra Dutra +7
Weakly Interacting Massive Particles (WIMPs) continue to be considered some of the best-motivated Dark Matter (DM) candidates. No conclusive signal, despite an extensive search pro…
Dark matter effects in modified teleparallel gravity
S. G. Vilhena, M. Dutra, O. Lourenço +1
This work investigates dark matter (DM) effects in compact objects in modified teleparallel gravity (MTG) in which a modification of Teleparallel Equivalent to General Relativity i…
Dark particle mass effects on neutron star properties from a short-range correlated hadronic model
M. Dutra, C. H. Lenzi, O. Lourenço
In this work we study a relativistic mean-field (RMF) hadronic model, with nucleonic short-range correlations (SRC) included, coupled to dark matter (DM) through the Higgs boson. W…
Probing feebly interacting dark matter with monojet searches
Jérôme Claude, Maíra Dutra, Stephen Godfrey
Dark matter may consist of feebly interacting massive particles (FIMPs) that never thermalized with the cosmic plasma. Their relic density is achieved via freeze-in for a wide rang…
Snowmass2021 Cosmic Frontier White Paper: Ultraheavy particle dark matter
Daniel Carney, Nirmal Raj, Yang Bai +25
We outline the unique opportunities and challenges in the search for "ultraheavy" dark matter candidates with masses between roughly and the Planck scale $m_{\rm pl}…
Dark matter component in hadronic models with short-range correlations
O. Lourenço, T. Frederico, M. Dutra
A relativistic mean field hadronic model with a dark matter (DM) particle coupled to nucleons including short-range correlations (SRC) is applied to study neutron stars (NS). The l…
EvoEMD: cosmic evolution with an early matter-dominated era
Maíra Dutra, Yongcheng Wu
We present EvoEMD, a framework to calculate the evolution of cosmic relics in a Universe with an early matter-dominated (EMD) era. There are mainly two aspects to consider in this…
PNJL model at zero temperature: three-flavor case
O. A. Mattos, T. Frederico, C. H. Lenzi +2
We propose a three-flavor version of the Polyakov-Nambu-Jona-Lasino (PNJL) model at zero temperature regime, by implementing a traced Polyakov loop () dependence in the scalar,…
A model for mixed warm and hot right-handed neutrino dark matter
Maíra Dutra, Vinícius Oliveira, C. A. de S. Pires +1
We discuss a model where a mixed warm and hot keV neutrino dark matter rises naturally. We arrange active and sterile neutrinos in the same multiplet, with the lightest s…
Testing freeze-in with axial and vector bosons
Catarina Cosme, Maíra Dutra, Stephen Godfrey +1
The freeze-in production of Feebly Interacting Massive Particle (FIMP) dark matter in the early universe is an appealing alternative to the well-known - and constrained - Weakly In…
Neutrino Portal to FIMP Dark Matter with an Early Matter Era
Catarina Cosme, Maíra Dutra, Teng Ma +2
We study the freeze-in production of Feebly Interacting Massive Particle (FIMP) dark matter candidates through a neutrino portal. We consider a hidden sector comprised of a fermion…
The moduli portal to dark matter particles
Maíra Dutra
The out-of-equilibrium production of dark matter (DM) from standard model (SM) species in the early universe (freeze-in mechanism) is expected in many scenarios in which very heavy…
Freeze-in production of dark matter through spin-1 and spin-2 portals
Maíra Dutra
In this conference, I have talked about two scenarios in which the out-of-equilibrium production of dark matter (DM) particles in the early universe is unavoidable. In the first on…
Moduli Portal Dark Matter
Debtosh Chowdhury, Emilian Dudas, Maíra Dutra +1
We show that moduli fields as mediators between the Standard Model and the dark sector can naturally lead to the observed relic abundance. Indeed, even if moduli are very massive,…
Freezing-in dark matter through a heavy invisible
Gautam Bhattacharyya, Maíra Dutra, Yann Mambrini +1
We demonstrate that in a class of the extension of the Standard Model (SM), under which all the Standard Model matter fields are uncharged and the additional neutral gauge…
MeV Dark Matter Complementarity and the Dark Photon Portal
Maíra Dutra, Manfred Lindner, Stefano Profumo +3
We discuss the phenomenology of an MeV-scale Dirac fermion coupled to the Standard Model through a dark photon with kinetic mixing with the electromagnetic field. We compute the da…

Giorgio Arcadi, Maíra Dutra, Pradipta Ghosh +5
Weakly Interacting Massive Particles (WIMPs) are among the best-motivated dark matter candidates. In light of no conclusive detection signal yet despite an extensive search program…
Majorana Dark Matter in Minimal Higgs Portal Models after LUX
Maíra Dutra, C. A. de S. Pires, P. S. Rodrigues da Silva
We consider the Singlet Majorana fermion dark matter model, in which the standard model particles interact with the dark sector through the mixing of a singlet scalar and the Higgs…
