TL;DR
This paper presents evidence that the Standard Model's CKM paradigm conflicts with experimental data, suggesting new physics at a scale below a few TeV, with implications for models like warped extra dimensions and a 4th quark generation.
Contribution
It provides a model-independent analysis showing the need for new physics to explain discrepancies in B-meson mixing and CP violation measurements.
Findings
Standard Model predicts sin(2 beta) too high by over 3 sigma.
New physics likely affects B-mixing and B_d -> psi K_s, not kaon-mixing.
Possible new physics scale is less than a few TeV, possibly as low as a few hundred GeV.
Abstract
Using firmly established experimental inputs such as epsilon_K, Delta M_d, Delta M_s, BR(B -> tau nu), gamma, V_cb along with corresponding lattice matrix elements which have been well studied and are in full QCD such as B_K, SU3 breaking ratio xi, B_Bs and in particular without using V_ub or the pseudoscalar decay constants f_Bd or f_Bs from the latice, we show that the CKM-paradigm now appears to be in serious conflict with the data. Specifically the SM predicted value of sin(2 beta) seems too high compared to direct experimental measured value by over 3 sigma. Furthermore, our studiy shows that new physics predominantly effects B-mixings and B_d -> psi K_s, and not primarily in kaon-mixing or in B -> tau nu. Model independent operator analysis suggests the scale of underlying new physics, accompanied by a BSM CP-odd phase, responsible for breaking of the SM is less than a few TeV,…
