Description
We present results of nucleon structure studies measured in 2+1 flavor QCD with physical light quarks in large spatial extents of about 10 and 5 fm. Our calculations are performed on 2+1 flavor gauge configurations generated by the PACS Collaboration with the stout-smeared $O(a)$ improved Wilson fermions and Iwasaki gauge action at $\beta$=1.82 corresponding to the lattice spacing of 0.085 fm. In this talk, we mainly focus on nucleon isovector scalar and tensor couplings. Especially, the tensor coupling is known as the 1st Mellin moment of transversity parton distribution and is itself related to the information of quark-EDM.
