Worldsheet
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 as a direct generalization of the world line concept for a point particle in special and general relativity. The type of string, the geometry of the spacetime in which it propagates, and the presence of long-range background fields (such as gauge fields) are encoded in a two-dimensional conformal field theory defined on the worldsheet. For example, the bosonic string in 26 dimensions has a worldsheet conformal field theory consisting of 26 free scalar bosons. Meanwhile, a superstring worldsheet theory in 10 dimensions consists of 10 free scalar fields and their fermionic superpartners.

Worldsheet
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 around 1967 as a direct generalization of the world line concept for a point particle in special and general relativity. The type of string, the geometry of the spacetime in which it propagates, and the presence of long-range background fields are encoded in a conformal field theory defined on the worldsheet. For example, the bosonic string in 26-dimensional Minkowski spacetime has a worldsheet conformal field theory consisting of 26 free scalar fields. Meanwhile, a superstring worldsheet theory in 10 dimensions consists of 10 free scalar fields and their fermionic superpartners. A string theory can be entirely formulated in terms of a Lagrangian Density across a worldsheet. In Bosonic string theory, the Lagrangian Density across the worldsheet is given by the Polyakov Lagrangian Density. In Type IIB Superstring theory, Type IIA Superstring theory and Type I Superstring theory, the Lagrangian Density across the worldsheet is the Ramond Neveu-Schwarz Lagrangian Density. When a consistent dirac matrix basis is chosen.
