Ramond–Neveu–Schwarz (RNS) formalism (named after
Pierre Ramond,
John H. Schwarz, and
André Neveu
André Neveu (; born 28 August 1946) is a French physicist working on string theory and quantum field theory who coinvented the Neveu–Schwarz algebra and the Gross–Neveu model.

was an early attempt to introduce fermions through the means of
supersymmetry
In a supersymmetric theory the equations for force and the equations for matter are identical. In theoretical and mathematical physics, any theory with this property has the principle of supersymmetry (SUSY). Dozens of supersymmetric theories ...
into string theory. In this theory, worldsheet embedded in spacetime is regarded as a bosonic field and the fermionic fields are regarded as the vectors of spacetime.
The theory can map out tachyon through
GSO projection

. Also, RNS formalism is equivalent to
GS formalism which has spacetime supersymmetry but without worldsheet supersymmetry.

In theoretical physics in general and string theory in particular, the Kalb–Ramond field (named after Michael Kalb and Pierre Ramond), also known as the Kalb–Ramond ''B''-field or Kalb–Ramond NS–NS ''B''-field, is a quantum field that t ...
