Results on the disconnected contributions for hadron structure
Abstract
We present results on the disconnected contributions to three point functions entering in studies of hadron structure. We use NF = 2+1+1 twisted mass fermions and give a detailed description on the results of the nucleon σ-terms, isoscalar axial charge and first moments of bare parton distributions for a range of pions masses. In addition we give the σ-terms and the computations are performed using QUDA code implemented on GPUs.
