如果假设一个自发破缺的局部超对称，大爆炸宇宙学意味着宇宙充满了引力子（${g}_{\frac{3}{2}}$）气体——可能是它的主要成分。从宇宙质量密度的观测界可以得出${m}_{{g}_{\frac{3}{2}}}\ensuremath{\lesssim}1$ keV。相应的，超对称破缺参数$F$满足$\sqrt{F}\ensuremath{\lesssim}2\ifmmode\times\else\texttimes\fi{}{10}^{3}$ TeV，要求在太电子伏特能量区出现新的超对称物理。导出了一个精确的和规则，并用于估计新状态产生的阈值和横截面。
If one assumes a spontaneously broken local supersymmetry, big-bang cosmology implies that the universe is filled with a gravitino (${g}_{\frac{3}{2}}$) gas---possibly its dominant constituent. From the observational bound on the cosmological mass density it follows that ${m}_{{g}_{\frac{3}{2}}}\ensuremath{\lesssim}1$ keV. Correspondingly, the supersymmetry breaking parameter $F$ satisfies $\sqrt{F}\ensuremath{\lesssim}2\ifmmode\times\else\texttimes\fi{}{10}^{3}$ TeV, requiring new supersymmetric physics in the teraelectronvolt energy region. An exact sum rule is derived and used to estimate the threshold and cross section for the production of the new states.
