Counting states in heterotic SO(32) string theory | A First Course in String Theory
.
c) Are there tachyonic states in heterotic string theory?
Write out the massless states of the theory (bosons and fermions) …
~~~
.
We have the following well-known bosonic string mass formulae:
open string:
closed string:

.
How come there is an extra at the beginning of the closed string formula?
