Goldstino
In particle physics, the gold Tino is a hypothetical Nambu - Goldstone fermion with spin 1 /2, which is formed by the spontaneous breaking of supersymmetry. It is closely related to the Goldstone boson of the Goldstone theorem, which describes the spontaneous collapse of the ordinary bosonic symmetry. As this is massless, unless the spontaneous breaking is a little explicit breaking of supersymmetry added; in this case the gold Tino developed a small mass.
In theories with global supersymmetry the gold Tino is a normal particles and possibly lightest supersymmetric particle as a candidate for dark matter.
In theories in which supersymmetry is a local symmetry ( gauge symmetry ), the gold Tino is absorbed by the gravitino. It is then the longitudinal component (ie in the direction of propagation ) and gives him a nonzero mass. This mechanism is closely related to the Higgs mechanism, which gives the W and Z bosons a nonzero mass.
Rudimentary bosonic superpartners of the gold Tinos, so-called Sgoldstinos, can also occur when super- multiplets are reduced to fields under certain circumstances.
