The frontier of cosmic microwave background (CMB) studies is to measure the CMB polarization. It provides a unique and powerful way to explore cosmic inflation, neutrino masses, and other possible light relics such as Axions. Furthermore, it enables us to search for the new physics which may exist behind the evolution of the universe through the critical tests of “tensions” in the LCDM model, most notably for the Hubble constant.
In this talk, I will introduce the CMB polarization physics and highlight the current experimental efforts. Also, I would like to advertise “POLARBEAR-2” in the latter half, which is a new CMB polarization receiver system designed, integrated, and tested at KEK.
