Description
Cosmological constraints with cosmic shear, galaxy-galaxy lensing, and galaxy-galaxy clustering, which is the so-called 3x2pt analysis have become a standard probe in recent weak lensing surveys. I will explain details of systematics specifically in the HSC 3x2pt analysis, including galaxy shapes, photometric redshift, baryonic effect, and assembly bias, which could provide a good starting point to think about systematics in beyond two-point statistics.
