Abstract
In this lattice QCD study we evaluate the nucleon spin decomposition to quarks and gluons contributions. We employ one gauge ensemble of maximally twisted mass fermions with two degenerate light quarks tuned to approximately reproduce the physical pion mass. We find that both spin sum and momentum sum are satisfied within the current statistical and systematic accuracy.
