3. Sub-GeV Dark Matter in Superfluid He-4: an Effective Theory Approach

One of the most urgent problems in physics is understanding the nature of Dark Matter: finding the Dark Matter in the form of a particle would open a brand new branch of physics beyond the Sandard Model. Many experiments until now have excluded a large spectrum of values for the WIMP exclusion plot, hence it may be relevant to consider a Dark Matter with lower mass. In a scattering based...

Light dark sector particles, especially bosons if coupled to the inflaton can be copiously produced during (p)reheating epoch courtesy to Bose enhancement. In many particle physics scenarios such particles are often invoked to resolve tensions with cosmological bounds from Big Bang Nucleosynthesis (BBN), Cosmic Microwave Background (CMB) and Large Scale Structure (LSS). We will discuss two...

5. Axion-Like particle as Light Dark Matter Portal

Today high precision accelerators represent a new frontier of detection for investigate on light dark sector. In particular I will illustrate why the axion-like particle can be a good Portal candidate as well as, by showing some phenomenological analysis, how PADME experiment, a fixed-target experiment in Laboratori Nazionali di Frascati, is able to test it.
