"Figure 13a" of "A search for microscopic black holes, string balls, and sphalerons in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

Expected and observed 95% CL upper limits on the pre-exponential factor for the sphaleron model with p(NCS) = 0.5.

针对p(NCS)=0.5的斯法勒隆模型（sphaleron model），其前指数因子的95%置信水平预期与观测上限。
