IMPLICATIONS OF D° — D° MIXING FOR NEW PHYSICS

摘要

I review constraints on possible New Physics interactions from D° — -D° mix-ing measurements. I consider the most general low energy effective Hamilto-nian and include leading order QCD running of effective operators. I discussconstraints from an extensive list of popular New Physics models, each ofwhich could be discovered at the LHC, that can generate these operators. Inmost of the scenarios, strong constraints that surpass those from other searchtechniques could be placed on the allowed parameter space using the existentevidence for observation of D meson mixing.
