Sgoldstino

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 hypotheisized that a sgoldstino particle might be responsible for the so far unexplained 750GeV diphoton excess[2] observed by Large Hadron Collider experiments.[3]
