Abstract

The POLARBEAR experiment is one of the few ongoing ground-based Cosmic Microwave Background (CMB) polarization experiment. The experiment is located in the Atacama desert in northern Chile and is designed to target both large and small scales anisotropies thanks to the combination of high angular resolution and large sky-fraction accessible from its mid-latitude site. We review the results of the analysis activity conducted on the data collected during the first observational campaign. These include the first measurement of B-modes of polarization on sub-degree angular scales together with the first reconstruction of the projected matter distribution between us and the epoch of recombination (lensing potential) using CMB polarization data alone. The measurement of the lensing potential was validated through cross-correlation of the matter distribution measured by the Herschel satellite. Finally, we discuss the upcoming experimental upgrades of the experiment.
