HADM: How attractive is dark matter?

Project funded by Fundação para a Ciência e a Tecnologia, I.P. (FCT) (Concurso para Financiamento de Projetos de Investigação Científica e Desenvolvimento Tecnológico em Todos os Domínios Ci), grant PTDC/FIS-AST/28920/2017. Funded amount: EUR 174,983, as stated by the source. Runs 2018-10-01 to 2022-09-30. Keywords: Dark Matter, Quantum Field Theory, Modified gravity, Sun, sun-like stars and neutron stars, Cosmology.

Abstract given by the source: Despite dark matter being predicted to be four times more abundant than baryonic matter and the major pressure-less ingredient for the formation of our universe, little is known about its actual nature. Dark Matter can be indeed made of a new kind of particles, as predicted by some quantum field theory (QFT) models, like the recent proposal of self-interacting cold dark matter [SICDM], and this is undoubtedly, the most widely accepted proposal to explain the well-known dark matter gravitational effects. However, more exotic possibilities have also been suggested within the last years. One of the most interesting, in light perhaps of its relation with the investigation of dark energy and comic inflation, and with their roots in particle physics, is to consider Dark Matter as an effect resulting from modifications to the Einstein?s general relativity (GR). Indeed, one can even consider a QFT model that combines GR with the standard model of elementary particles. Therefore, some pertinent questions arise, such as: How much a generalized GR modifies the dark matter physics? What will be the properties of this ?geometric dark matter?? These are the central problems that will be analyzed within the presented project. In particular, the project will start by testing the validity of three specific models, against astrophysical observational data obtained from two distinct cosmological scales: ?stars? and ?large-scale baryonic structure?. By taking advantage of the expertise of our team members in GR and QFT models, solar and stellar physics, compact stars, and cosmic structure formation, we will make use of the available observational data coming from different fields of research: helioseismology, solar neutrinos, asteroseismology, compact (neutron) stars, cosmological surveys and particle physics experimental data, to identify which models are in agreement with these observational sets. The results obtained will allow us to give an answer to the following questions: How [shortened; the full text is on the OpenAIRE page]
