Description

We present the first lattice QCD computation of the light quarks and strange helicity PDFs. We used a $N_f=2+1+1$ lattice ensemble generated by the Extended Twisted Mass collaboration (ETMC), with pion mass $M_{\pi }\approx 250\mathrm{G}\mathrm{e}\mathrm{V}$, $M_{\pi }L\approx 3.8$ and lattice spacing $a=0.0938(2)(3)\mathrm{f}\mathrm{m}$. Momentum smearing is employed in order to improve the signal-to-noise ratio, allowing for the computation of the matrix elements up to nucleon boost momentum $P_3=1.24\mathrm{G}\mathrm{e}\mathrm{V}$.
