"The Mirror Crack'd: Evidence for an Anomalous Like-Sign Dimuon Charge Asymmetry"
The D0 experiment running on the Tevatron Collider at Fermilab has recently observed an anomalously large like-sign dimuon charge asymmetry that may be indicating a potential new source of CP violation beyond the Standard Model. The importance of CP violation and its source within the Standard Model is first discussed. The technique of using neutral meson particle-antiparticle oscillations to explore this CP violation is described and then the measurement presented. Intriguing indications of a similar effect in a separate analysis are shown as well as more far-fetched implications on CPT/Lorentz violation.
