我们在测量介导的低能量超对称破断框架内评估大型强子对撞机的超对称到达，假设中性子是第二轻的粒子，并且它迅速衰变为逃避检测的引力子。我们发现最大范围是通过搜索主要来自电荷和中性子产生的包含γγ+ E / teevents获得的。假设积分光度为10 fb−1，我们发现大型强子对撞机实验将能够探测到模型参数Λ > 400 TeV的值，对应于mg / o≤2.8 TeV。对模型参数Λ的测量可能来自光子pTspectrum。
We evaluate the supersymmetry reach of the Large Hadron Collider within the gauge-mediated low energy supersymmetry breaking framework, assuming that a neutralino is the second lightest sparticle and that it decays promptly into a gravitino which escapes detection. We find that the maximum reach is obtained via a search for inclusive γγ+ E /Tevents coming dominantly from chargino and neutralino production. Assuming an integrated luminosity of 10 fb−1, we find that LHC experiments will be able to probe values of the model parameter Λ≲400 TeV, corresponding to mg ̃≤2.8 TeV. A measure of the model parameter Λ may be possible from the photon pTspectrum.
