Editing Supergravity (section)

===mSUGRA===
mSUGRA means minimal SUper GRAvity. The construction of a realistic model of particle interactions within the ''N'' = 1 supergravity framework where supersymmetry (SUSY) breaks by a super [[Higgs mechanism]] carried out by [[Ali Chamseddine]], [[Richard Arnowitt]] and [[Pran Nath (physicist)|Pran Nath]] in 1982. Collectively now known as minimal supergravity Grand Unification Theories (mSUGRA GUT), gravity mediates the breaking of SUSY through the existence of a [[hidden sector]]. mSUGRA naturally generates the Soft SUSY breaking terms which are a consequence of the Super Higgs effect. Radiative breaking of electroweak symmetry through [[Renormalization]] Group Equations (RGEs) follows as an immediate consequence. 
Due to its predictive power, requiring only four input parameters and a sign to determine the low energy phenomenology from the scale of Grand Unification, it is widely investigated in [[particle physics]].
