= 500$ GeV and $\tan \beta =10$ , the lifetimes can be divided up into the following interesting regimes:

-   Cosmologically significant ($\epsilon_\text{max} \lesssim 10^{-10}$ GeV): The decays of squarks with lifetimes greater than about 100 seconds would disrupt the predictions of big bang nucleosynthesis, see reference [@Kusakabe:2009jt] for example, and would therefore be ruled out.

-   Collider stability ($10^{-10} \text{ GeV } \lesssim \epsilon_\text{max} \lesssim 10^{-7} \text{ GeV }$): In this regime, the decay length of the squark is longer than the radius of the LHC detectors, about ten meters in size. Such squarks would hadronize and are referred to as $R$-hadrons. These states would be detectable through their activity in the hadronic calorimeter of the detectors and have been studied in references [@Raby:1997pb; @Berger:2003kc; @Buckley:2010fj; @Aad:2011yf; @Aad:2012zn; @Aad:2012pra], for example.

-   Displaced vertices ($10^{-7} \text{ GeV } \lesssim \epsilon_\text{max} \lesssim 10^{-4} \text{ GeV}$): Squark decays inside an LHC detector with a decay length greater than a millimeter have a large enough displaced vertex from the squark origin to be measured. Such vertices, in a phenomenologically similar scenario, were discussed in [@Graham:2012th]. Experimentally, some searches for displaced vertices have been performed in references [@Aad:2011zb; @Aad:2012zx; @Chatrchyan:2012jwg].
