Theoretical Elementary Particle Physics

Prof. Alejandro Ibarra

Research Field

The Standard Model of Particle Physics provides an excellent description of nature at distances larger than E-16 cm, or equivalently energies smaller than 100 GeV. However, there are reasons to believe that the Standard Model is incomplete and needs to be extended. For instance, the Standard Model does not provide any explanation to the observed fermion masses and mixing angles or to the large hierarchy between the electroweak scale and the Planck scale. It does not provide either any explanation for some observed cosmological parameters, such as the baryon asymmetry of the Universe, the relic density of dark matter or the amount of dark energy. Our research group considers extensions of the Standard Model that might account for these observations and we study their consequences for present and future experiments.

Synchrotron radiation and indirect detection of dark matter
Dark matter particles could annihilate in our galaxy, producing electrons in the final state. The electrons would swirl around the Milky Way's magnetic field, generating synchrotron radiation in the GHz range. This radiation could then be observed at Earth, thereby providing an “indirect” signature of dark matter's existence beyond its gravitational influence on astronomical objects. This bachelor thesis will analyze the properties of the synchrotron radiation produced in dark matter annihilations (emitted power, angular dependencies, frequency spectrum). As an application, we will consider the synchrotron radiation from the Smith's Cloud, which contains large amounts of dark matter and very little hydrogen, thus constituting an excellent target for dark matter detection.
