摘要
En 中文
In this work, we address two paradoxes. The first is that the measured dark-matter relic density can be satisfied with new physics at O(100GeV-1TeV), while the null results from direct-detection experiments place lower bounds of O(10TeV) on a new-physics scale. The second puzzle is that the severe suppression of lepton-flavor-violating processes involving electrons, e.g. mu -> 3e, tau -> e mu mu, etc., implies that generic new-physics contributions to lepton interactions cannot exist below O(10-100TeV), whereas the 3.6 sigma deviation of the muon g - 2 from the standard model can be explained by a new physics scale
