摘要: Numerous experiments currently underway offer the potential to indirectly probe new charged particles with masses at weak scale. For example, tentative excess in h → γγ decays and gamma-ray line Fermi-LAT data have recently attracted attention as possible one-loop signatures of particles. We explore interplay between such signals, dark matter direct detection through Higgs exchange, measurements electron EDM, by studying size these effects several models. compute relationship among couplings probed different experiments. In particular, models which both interact a detectable level typically induce, loop level, that are around current sensitivity. Intriguingly, DM γγ, two-loop EDMs, loop-induced rates all coming within range existing for approximately same particle masses, offering prospect an exciting coincidence signals collider, astrophysical, underground atomic physics measurements.
