Abstract
We present results on the spin and quark content of the nucleon using Nf = 2
twisted mass cloverimproved
fermion simulations with a pion mass close to its physical value. We use
recently
developed methods to obtain accurate results for both connected and
disconnected contributions.
We provide results for the axial charge, quark and gluon momentum fraction as
well as the light, strange and charm $\sigma$-terms.
