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.
In 2016, Petersson and Torre hypothesized that a sgoldstino particle might be responsible for the observed 750 GeV diphoton excessMore data about this phenomenon LHC will release in Fall 2016 - http://physics.aps.org/synopsis-for/10.1103/PhysRevLett.116.151805 observed by Large Hadron Collider experiments.
