Counting states in heterotic SO(32) string theory | A First Course in String Theory

.

d) Write a generating function for the full set of GSO-truncated states in the left-moving sector (include both NS’+ and R’+ states).

Use the convention where counts the number of states with .

Use and an algebraic manipulator to find the total number of states in heterotic string theory at .

.

The left R’+ sector:

.

.

However, there are ground states and ground states :

.

“Keep only states with ; this defines the left R’+ sector.”
