Roper State from Overlap Fermions

Mingyang Sun, Ying Chen, Gen Wang +11

The Roper state is extracted with valence overlap fermions on a $2 + 1$ -flavor domain-wall fermion lattice (spacing $a = 0.114$ fm and $m_{π} = 330$ MeV) using both the Sequential Empi…

Towards the nucleon hadronic tensor from lattice QCD

Jian Liang, Terrence Draper, Keh-Fei Liu +2

We present the first calculation of the hadronic tensor on the lattice for the nucleon. The hadronic tensor can be used to extract the structure functions in deep inelastic scatter…

Ratio of strange to $u / d$ momentum fraction in disconnected insertions

Jian Liang, Mingyang Sun, Yi-Bo Yang +2

The ratio of the strange quark momentum fraction $⟨ x ⟩_{s + s ˉ}$ to that of light quark $u$ or $d$ in disconnected insertions (DI) is calculated on the lattice with…
