  The physical particles in supersymmetric Yang-Mills theory (SYM) are bound
states of gluons and gluinos. We have determined the masses of the lightest
bound states in SU(3) $\mathcal{N}=1$ SYM. Our simulations cover a range of
different lattice spacings, which for the first time allows an extrapolation to
the continuum limit. Our results show the formation of a supermultiplet of
bound states, which provides a clear evidence for unbroken supersymmetry.
