Light Stops and Observation of Supersymmetry at LHC RUN-II

Understand

Light stops consistent with the Higgs boson mass of $\sim126\,{\rm GeV}$ are investigated within the framework of minimal supergravity.

• It is shown that models with light stops which are also consistent with the thermal relic density constraints require stop coannihilation with the neutralino LSP.
• The analysis shows that the residual set of parameter points with light stops satisfying both the Higgs mass and the relic density constraints lie within a series of thin strips in the $m_0-m_{1/2}$ plane for different values of $A_0/m_0$.
• Consequently, this region of minimal supergravity parameter space makes a number of very precise predictions.
