The authors' main claim We show that the combined LHC and relic abundance constraints rule out most of the MSSM parameter space except a very narrow region with very large $\tan \beta~(\sim 50)$.

The constraints imposed on the Minimal Supersymmetric Standard Model (MSSM) parameter space by the Large Hadron Collider (LHC) Higgs mass limit and gluino mass lower bound are revisited. We also analyze the thermal relic abundance of lightest neutralino, which is the Lightest Supersymmetric Particle (LSP). We show that the combined LHC and relic abundance constraints rule out most of the MSSM parameter space except a very narrow region with very large $\tan \beta~(\sim 50)$. Within this region, we emphasize that the spin-independent scattering cross section of the LSP with a proton is less than the latest Large Underground Xenon (LUX) limit by at least two order of magnitudes. Finally, we argue that non-thermal Dark Matter (DM) scenario may relax the constraints imposed on the MSSM parameter space. Namely, the following regions are obtained: $m_0\simeq {\cal O}(4)$ TeV and $m_{1/2}\simeq 600$ GeV for low $\tan\beta~(\sim 10)$; $m_0\sim m_{1/2} \simeq {\cal O}(1)$ TeV or $m_0 \simeq {\cal O}(4)$ TeV and $m_{1/2} \simeq 700$ GeV for large $\tan \beta~(\sim 50)$.

It is remarkable that these allowed points are much larger than the corresponding ones in the MSSM, where no point with bino-like is allowed and much less points for higgsino-like at very large $tanβ$ are allowed [ref] .

However, the constraints from LHC data (from the Higgs boson properties as well as void searches for additional Higgs and SUSY states) combined with cosmological relic density and DM direct detection data rule out all of the MSSM parameter space except a very narrow region of it [ref] .

Many of these are either Bayesian (e.g. [ref] ) or frequentist (e.g. [ref] ), or both ( [ref] ), but there are also many studies using other techniques or constraints to perform the analysis (e.g. [ref] ).

However, the relic abundance depends on the details of the underlying cosmology (thermal or non-thermal abundance) so its constraints will not be considered here [ref] .

Here we used micrOMEGAs [ref] to compute the complete relic abundance of the lightest neutralino, taking into account the possibility of having co-annihilation with the next-to-lightest supersymmetric particle, which is typically the lightest stau.

Furthermore, the LHC lower limit on the gluino mass: $m_g̃ 1.4$ TeV [ref] , excluded the values of $m_1/2 < 620$ GeV that was allowed by Higgs mass constraints for $m_0 > 4$ TeV.

In this figure the red regions correspond to a relic abundance within the measured limits [ref] : 0.09<Ωh^2<0.14 It is noticeable that with low $tanβ (∼10)$, this region corresponds to light $m_1/2$ $(< 500$ GeV$)$, where a significant co-annihilation between the LSP and stau took place.
