      An argentinian guide to inflation 20m

      Nowadays, more robust theories suggest that a period known as inflation occurred in the first fractions of a second after the Big Bang. The inflationary period has not yet been confirmed by experiments, but it should have left an imprint on the Cosmic Microwave Background, the oldest light we can observe. We may finally be able to detect this signal through the QUBIC experiment.

      The low energy excess in dark matter and neutrino experiments 20m

      Sub-GeV dark matter and low energy neutrino-nucleus scattering experiments require extremely low energy thresholds and minimal background levels. While an extensive research is being carried out to push the sensitivity of particle detectors, an unknown type of background affects basically all low-threshold experiments in the field. This background has an energy spectrum that sharply rises at low energy, precisely in the signal region, and a complete understanding of its origin(s) is still an open question.
      In this talk I will investigate this “low energy excess”, focusing on its features and possible explanations.
