Talk Title:  “Probing physics at the TeV scale—and above—with room-scale experiments”

Abstract:

Remarkably, it is possible to use small experiments—with teams of a few people, in a university lab—to probe for well-motivated phenomena at very high energy scales.  This talk will focus particularly on experiments searching for CP-violating electric dipole moments (EDMs) of the electron and the proton.  In a very broad class of theoretical models, the expected size of these EDMs is far larger than expected in the Standard Model.  Recent advances in experimental techniques are now enabling rapid improvements in the sensitivity of these searches.  For example, the latest result of our ACME experiment, which set an improved limit on the size of the electron’s EDM, can be interpreted as excluding certain particles with mass below several TeV, within a set of viable models.  Our newly-launched CeNTREX search for the proton EDM is projected to be sensitive to CP-violating effects at similar scales, but in the hadronic sector. Ongoing and planned improvements to both experiments—which will leverage techniques for laser cooling and trapping of molecules, developed recently in our group—can extend the energy reach of both experiments far beyond the range directly accessible at colliders
