Description
The $x$-dependent behavior of gluons remains important for providing insight to the structure of hadrons. In this talk, we present preliminary results for continuum limit extraction of the unpolarized gluon PDF in the proton from lattice QCD using four $N_f=2+1+1$ ensembles of maximally twisted mass fermions with clover improvement with pion mass $m_{\pi}\approx250~\mathrm{MeV}$ and lattice spacings ranging from $a\approx 0.093 - 0.057~\mathrm{fm}$. Additionally, we present results ratios of gluon moments $\langle x^3 \rangle/\langle x \rangle$ extracted from the same nonlocal matrix elements as the PDF using the OPE formalism.
