Possible evidence for the breakdown of the CKM-paradigm of CP-violation

AbstractUsing primarily experimental inputs for S(Bd→ψKs), ΔMBs, ΔMBd, BR(B→τν) and ϵK along with necessary inputs from the lattice, we find that the measured value of sin(2β) is smaller than expectations of the Standard Model by as much as 3.3σ, and also that the measured value of the BR(B→τν) seems to be less than the predicted value by about 2.8σ. However, through a critical study we show that most likely the dominant source of these deviations is in Bd(s) mixings and in sin(2β) and less so in B→τν, and also that the bulk of the problem persists even if input from ϵK is not used. The fact that kaon mixing and ϵK are not the dominant source of the deviation from the Standard Model has the very important consequence that model independent considerations imply that the scale of the relevant new CP-violating physics is below O(2TeV), and possibly even a few hundred GeVs, thus suggesting that direct signals of the new particle(s) may well be accessible in collider experiments at the LHC and perhaps even at the Tevatron
