What is "sgoldstino"

n. (context physics English) The theoretical superpartner of a goldstino.

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 so far unexplained 750 GeV diphoton excess observed by Large Hadron Collider experiments.
