DESCRIPTION:There are several observables in processes with heavy quarks t
 hat appear to be anomalously large experimentally: the forward-backward as
 ymmetry in ttbar production (A_FB)\, the direct CP asymmetry in two body D
  decays (Delta A_CP) and the probes of lepton universality in semileptonic
  B decays. I will give an overview of these processes\, both the present e
 xperimental status as well as standard model and new physics interpretatio
 ns. For instance\, there are tight constraints on NP models that could exp
 lain A_FB. Many NP models that were on the market before the first top res
 ults from the LHC are now in tension with the charge asymmetry measurement
 s at the LHC. For general enough new physics models the correlation betwee
 n the two observables is lost\, however. On the other hand\, there is some
  support for the SM origin of Delta A_CP. Reasonable NP models can also ex
 plain Delta A_CP and one can distinguish between the two of them experimen
 tally using just charm decay data. Finally\, I will show that at least in 
 the effective field theory a consistent picture of lepton universality vio
 lation recently hinted at by BaBar is possible and what types of models co
 uld explain it.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=19135
