Counting states in heterotic SO(32) string theory | A First Course in String Theory
.
Paraphrasing the description of heterotic (closed) string theory:
—
- right-moving part
an open superstring theory
sector:
sector:
- “The standard GSO projection down to NS+ and R- applies.”
.
- left-moving part
a peculiar bosonic openstring theory
There are totally 24 transverse coordinates
- 8 bosonic coordinates
with oscillators
-
16 peculiar bosonic coordinates
- can be replaced by 32 two-dimensional left-moving fermion fields,
(anti-commuting) fermion fields
has
and
sectors
- can be replaced by 32 two-dimensional left-moving fermion fields,
- 8 bosonic coordinates
-
: oscillators

given
defines the left
sector
-
: oscillators
act on
ground states
