Massive chiral superstring supersymmetry multiplet
= Massive chiral superstring supersymmetry multiplet
{title2=$128_B+128_F=256$}
At the first massive chiral level, 128 NS bosons and 128 R fermions furnish a massive multiplet with 16 real supercharges and no central charge. Its rest-frame <supersymmetry> algebra has eight fermionic creation operators, producing $2^8=256$ states. The massive little-group representations are $44+84$ for the bosons and a 128-dimensional vector-spinor for the fermions.
