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…
