CEBAF Center, Room L102

*Yi-Bo Yang**(MSU)*
*Gluon Spin and Helicity of the Proton from Lattice QCD
*
Understanding the role of gluons inside the proton is an important task
for both ongoing experiments and the future EIC. In this talk,
I will present the first lattice-QCD result including that at
physical pion mass for the gluon spin/helicity contribution
in the proton, using a chiral fermion action.
The first lattice result for the gluon total helicity S_G in
the MSbar scheme 10GeV^2 will also be presented, including
a discussion of the general strategy and difficulties in the lattice 
calculations.
This work has been highlighted as Viewpoint in PRL 
(https://journals.aps.org/prl/issues/118/10).
