Counting states in heterotic SO(32) string theory | A First Course in String Theory
.
At any mass level of the heterotic string, the spacetime bosons are obtained by “tensoring” all the left states (NS’+ and R’+) with
with the right-moving NS+ states with
.
Similarly, the spacetime fermions are obtained by tensoring all the left states (NS’+ and R’+) with with the right-moving R- states with
.
c) Are there tachyonic states in heterotic string theory?
Write out the massless states of the theory (bosons and fermions) …
