- In
string theory, a
worldsheet is a two-dimensional
manifold which describes the
embedding of a
string in spacetime. The term was
coined by
Leonard Susskind...
- an
action of the two-dimensional
conformal field theory describing the
worldsheet of a
string in
string theory. It was
introduced by
Stanley Deser and Bruno...
- dimensions. Both
theories are
based on
oriented closed strings. On the
worldsheet, they
differ only in the
choice of GSO projection. They were
first discovered...
-
through spacetime, a
string sweeps out a two-dimensional
surface called its
worldsheet. This is
analogous to the one-dimensional
worldline traced out by a point...
- of
possible vertex operators in the
worldsheet conformal field theory (CFT)—usually
those with
specific worldsheet fermion number and
periodicity conditions...
- the
string means that only
interaction corresponding to an
orientable worldsheet are
allowed (e.g., two
strings can only
merge with
equal orientation)...

Interaction in the
quantum world:
worldlines of point-like
particles or a
worldsheet swept up by
closed strings in
string theory...
-
interactions between quarks. In
order for a
string theory to be consistent, the
worldsheet theory must be
conformally invariant. The
obstruction to

- (RNS)
formalism is an
approach to
formulating superstrings in
which the
worldsheet has
explicit superconformal invariance but
spacetime supersymmetry is...
