Probing new physics through B mixing : status, benchmarks and prospects.

Ball, P. and Fleischer, R. (2006) 'Probing new physics through B mixing : status, benchmarks and prospects.', European physical journal C., C48 . pp. 413-426.


As is well known, B0 d,s–B̄0 d,s mixing offers a profound probe into the effects of physics beyond the standard model. The data obtained at the e+e- B factories have already provided valuable insights into the Bd-meson system, and very recently also the B0 s–B̄0 s oscillation frequency ΔMs has been measured at the Tevatron. We give a critical discussion of the interpretation of these data in terms of model-independent new-physics parameters. We address in particular the impact of the uncertainties of the relevant input parameters, set benchmarks for their accuracies as required by future precision measurements at the LHC, and explore the prospects for new CP-violating effects in the Bs system. To complement our model-independent analysis, we also discuss the constraints imposed by the CDF measurement of ΔMs on popular models of new physics, namely scenarios with an extra Z’ boson and supersymmetry. We find that the new data still leave sizeable room for new-physics contributions to B0 s–B̄0 s mixing, which could be detected at the LHC.
