Search for sgoldstino in $e^{+}e^{-}$ collisions at $\sqrt{s}$ from 189 to 202 GeV with the DELPHI experiment
Recent theoretical studies have proposed new phenomenological scenarios where the gravitino is light and the sgoldstino can be light and so be detectable at LEP. A novelty of this framework is that the sgoldstino being a SM particle, its decay chains do not involve other supersymmetric particles, li...
