We compute the pion and kaon matrix elements with non-local staple-shaped operators using an $N_f=2+1+1$ twisted mass fermion ensemble. The lattice has volume $24^3 * 48$, lattice spacing $a=0.093 \ fm$ and a pion mass of $350 \ MeV$. We employ momentum smearing to improve the signal as we increase the momentum. We explore momenta corresponding to $1.11 \ GeV$ and $2.78 \ GeV$. We also study the mixing pattern of the operators under renormalization and implement an RI/MOM scheme for the non-perturbative renormalization.
