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.

goldstino
The goldstino is the NambuāGoldstone fermion emerging in the spontaneous breaking of supersymmetry. It is the close fermionic analog of the NambuāGoldstone bosons controlling the spontaneous breakdown of ordinary bosonic symmetries.

relativistic quantum field theories
In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. QFT is used in particle physics to construct physical models of subatomic particles and ...

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

The Large Hadron Collider (LHC) is the world's largest and highest-energy particle collider. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and hundr ...
