A sgoldstino is any of the spin-0

superpartner In particle physics, a superpartner (also sparticle) is a class of hypothetical elementary particles predicted by supersymmetry, which, among other applications, is one of the well-studied ways to extend the Standard Model of high-energy physics. ...

s 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 excess The 750 GeV diphoton excess in particle physics was an anomaly in data collected at the Large Hadron Collider (LHC) in 2015, which could have been an indication of a new particle or resonance. The anomaly was absent in data collected in ...
