"Direct detection of dark matter: from WIMPS to dark photons"

The matter that we know makes up less than 5% of the Universe. From astronomical and cosmological observations we have strong evidence that dark matter exists and it is the main component of the mass budget of the universe. The nature of dark matter is yet to be discovered and is one of the most pressing questions in physics. Direct detection experiments aim to detect the interaction of galactic dark matter with terrestrial nuclei. Weekly interacting massive particles (WIMP) are a likely candidate for dark matter, but axions, hidden photons and other candidates are also considered. In this talk we will review currently available major technologies being pursued by various collaborations, with emphasis on the CCD technology used by the DAMIC (Dark Matter in CCDs) experiment. We will present the evidence for and against light WIMPS as dark matter candidates and discuss other dark matter candidates such as dark photons and others.
