Applications of the WW-type approximation to SIDIS
/ Bastami, S. (Connecticut U.) ; Avakian, H. (Jefferson Lab) ; Efremov, A.V. (Dubna, JINR) ; Musch, B.U. (Regensburg U.) ; Parsamyan, B. (CERN) ; Prokudin, A. (Penn State U., Berks-Lehigh Valley) ; Schlegel, M. (New Mexico State U.) ; Schnell, G. (Basque U., Bilbao ; IKERBASQUE, Bilbao) ; Schweitzer, P. (Connecticut U.) ; Tezgin, K. (Connecticut U.) et al.
We explore the complete cross-section for the production of unpolarized hadrons in semi-inclusive deep-inelastic scattering up to power-suppressed $\mathcal{O}(1/Q^2)$ terms in the Wandzura-Wilczek-type (WW-type) approximation, which consists in systematically assuming that $\bar{q}gq$-correlators are much smaller than $\bar{q}q$-correlators. Under the applicability of WW-type approximations, certain relations among transverse momentum dependent parton distribution functions (TMDs) and fragmentation functions (FFs) occur which are used to approximate SIDIS cross-section in terms of a smaller subset of TMDs and FFs.

Semi-Inclusive Deep Inelastic Scattering in Wandzura-Wilczek-type approximation
/ Bastami, S. (Connecticut U.) ; Avakian, H. (Jefferson Lab) ; Efremov, A.V. (Dubna, JINR) ; Kotzinian, A. (Yerevan Phys. Inst. ; INFN, Turin) ; Musch, B.U. (Regensburg U.) ; Parsamyan, B.

(Connecticut U. ; Tubingen U.) et al.
We present the complete cross-section for the production of unpolarized hadrons in semi-inclusive deep-inelastic scattering up to power-suppressed ${\cal O}(1/Q^2)$ terms in the Wandzura--Wilczek-type approximation which consists in systematically assuming that $\bar{q}gq$--terms are much smaller than $\bar{q}q$--correlators. We compute all twist-2 and twist-3 structure functions and the corresponding asymmetries, and discuss the applicability of the Wandzura--Wilczek-type approximations on the basis of available data.

Update of Euclidean windows of the hadronic vacuum polarization
/ RBC Collaboration
We compute the standard Euclidean window of the hadronic vacuum polarization using multiple independent blinded analyses. We improve the continuum and infinite-volume extrapolations of the dominant quark-connected light-quark isospin-symmetric contribution and address additional sub-leading systematic effects from sea-charm quarks and residual chiral-symmetry breaking from first principles. [...]
