Spectral distortions of the CMB provide independent and complementary probes to study energy injection processes in the early universe. In this work was obtained the spectral $\mu$-distortion associated with phase transition of the dark particles in the BDM model. Several scenarios were simulated numerically with parameters: $a_{c} = [4.9 \times 10^{-7}, 3.3 \times 10^{-6}]$, $ f_{eff} =...
In this talk I will give a short review of how the Higgs sector could give us some clues of physics beyond the Standard Model. Precision measurements of the Higgs coupling in colliders might tell us something about the scale of a more fundamental theory. By the other hand, and extended Higgs sector could work as a portal for WIMP Dark Matter. The talk will be based on 1912.01758 [hep-ph] and...
While incomplete, the experimental success and theoretical consistency of the Standard Model suggest that if we are to find new particles or interactions at low energies, they should be very weakly coupled to ordinary matter and likely organized in new secluded or "dark" sectors. In this way, our best chance for discovery lies in low-background and high-intensity experiments, such as neutrino...
Cosmological and astrophysical observations predict that around 25$\%$ of the energy content of the universe is made of dark matter. The nature of dark matter is currently unknown and a lot of effort is placed in the hunt for dark matter. One of the candidates for dark matter is the axion, a particle first introduced to solve the strong Charge-Parity problem of the Standard Model.
The CERN...
