A sgoldstino is any of the spin-0 superpartners of the goldstino in relativistic quantum field theories with spontaneously broken supersymmetry.
The term sgoldstino was first used in 1998.
[1] In 2016, Petersson and Torre hypothesized that a sgoldstino particle might be responsible for the observed 750 GeV diphoton excess[2] observed by Large Hadron Collider experiments.
