Sgoldstino

{{Short description|Superpartners in relativistic quantum field theories}}

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.{{Cite journal|last1=Petersson|first1=Christoffer|last2=Torre|first2=Riccardo|date=2016-04-12|title=The 750 GeV diphoton excess from the goldstino superpartner|journal=Physical Review Letters|volume=116|issue=15|doi=10.1103/PhysRevLett.116.151804|issn=0031-9007|arxiv = 1512.05333 |bibcode = 2016PhRvL.116o1804P|pmid=27127959|page=151804|s2cid=5488363 }}
