The Mellin moments \(\langle x \rangle\) and \(\langle x^2 \rangle\) for the pion and kaon from lattice QCD

We present a calculation of the pion quark momentum fraction, \(\langle x \rangle\), and its third Mellin moment \(\langle x^2 \rangle\). We also obtain directly, for the first time, \(\langle x \rangle\) and \(\langle x^2 \rangle\) for the kaon using local operators. We use an ensemble of two degen...
