What is SuperField?

What is SuperField?

A superfield is a function defined in superspace which properly packages the various fields of a supermultiplet, namely, the array of fermion and boson fields related among themselves by supersymmetry. Superfields were introduced by Abdus Salam and John Strathdee in 1979.

What is a hypermultiplet?

Hypermultiplet. A hypermultiplet is a type of representation of an extended supersymmetry algebra, in particular the matter multiplet of N=2 supersymmetry in 4 dimensions, containing two complex scalars Ai, a Dirac spinor ψ, and two further auxiliary complex scalars Fi.

What is the definition of a superfield?

Definitions for superfield su·per·field. A superfield is a function defined in superspace which properly packages the various fields of a supermultiplet, namely, the array of fermion and boson fields related among themselves by supersymmetry. Superfields were introduced by Abdus Salam and John Strathdee in 1979.

How is a vector superfield related to a gauge field?

However, a vector superfield depends on all coordinates. It describes a gauge field and its superpartner, namely a Weyl fermion that obeys a Dirac equation . V is the vector superfield ( prepotential) and is real ( V = V ). The fields on the right hand side are component fields. where Λ is any chiral superfield. is gauge invariant.

What kind of superfields depend on all coordinates?

Every superfield, i.e. a field that depends on all coordinates of the superspace, may be expanded with respect to the new fermionic coordinates. There exists a special kind of superfields, the so-called chiral superfields, that only depend on the variables θ but not their conjugates (more precisely,

When did Abdus Salam invent the superfield?

A superfield is a function defined in superspace which properly packages the various fields of a supermultiplet, namely, the array of fermion and boson fields related among themselves by supersymmetry. Superfields were introduced by Abdus Salam and John Strathdee in 1979. How to pronounce superfield? How to say superfield in sign language?
