{c}
{synonym}
A <closed string> sector with left-moving <Neveu–Schwarz sector> excitations and right-moving <Ramond sector> excitations. Its spacetime states are <fermions>. The <string intercepts> differ, so the pair of oscillator vacua is not level matched: $N_L-1/2=N_R$. After the supersymmetric <GSO projection>, the lowest allowed states have $(N_L,N_R)=(1/2,0)$ and are a massless <gravitino> and <dilatino>.
