In this project we ask if it is possible to deduce the number of QCD colors (Nc) directly from low energy experiments with photons, pions, eta/eta’ mesons and kaons. Contrary to the common lore, it is impossible to see the Nc with just pions and photons and are the decays of the eta/eta’ meson, η/η'→γγ and η/η'→ππγ that are proportional to Nc and should replace the textbook process π→γγ lending support to Nc=3.

Axions are hypothetical particles that appear in well-motivated extensions of the Standard Model and are very attractive for being able to explain some of the open questions in particle physics, such as the strong CP-problem or the origin of dark matter in the universe. We will perform a thorough theoretical investigation of the phenomenological impact of axion interactions with SM particles, with special emphasis on hadronic particles at low energies.
GMV offers the opportunity to participate in a remunerated project for the Final Master's Thesis (TFM). The increasing density of satellites and space debris in Earth's orbit poses significant challenges for space operations and safety. Traditional ground-based observation methods have limitations in detecting small-sized debris, especially those smaller than 10cm.
