<b>Overview of Hadron Structure from Lattice QCD</b><br>
</div>
<br>
Understanding hadron structure from first principles is considered a
milestone of hadron physics <br>
and numerous experiments have been devoted to its study, starting
with the measurements of the<br>
electromagnetic form factors more than 50 years ago. Lattice QCD
(LQCD) is a powerful approach for<br>
the ab initio calculation of hadron observables. Emerging results
form LQCD are providing input to <br>
phenomenology, as well as to Physics beyond the Standard Model. This
is due to the impressive <br>
progress in the simulation of LQCD mainly due to improvements in the
algorithms, development <br>
of new techniques and increase in computational power that have
enabled simulations to be carried <br>
out at parameters very close to their physical values. In this talk
we will review results obtained with <br>
simulations at or near to the physical value of the pion mass, such
as the nucleon axial charge and the <br>
first moments parton distributions, for both the valence and sea
quark contributions, and discuss their<br>
implications on the spin content of the nucleon. Selected results on
the electromagnetic form factors <br>
and radii, the quark content of the nucleon and on the neutron
electric dipole moment are also discussed.
