Issue Date: | Dec-2009 | Publisher: | PhysMath Central | Abstract: | We combine all the available experimental information on Bs mixing, including the very recent tagged analyses of Bs → J/Ψϕ by the CDF and DØ collaborations. We find that the phase of the Bs mixing amplitude deviates more than 3σ from the Standard Model prediction. While no single measurement has a 3σ significance yet, all the constraints show a remarkable agreement with the combined result. This is a first evidence of physics beyond the Standard Model. This result disfavours New Physics models with Minimal Flavour Violation with the same significance. | URI: | http://hdl.handle.net/2307/229 | ISSN: | 1754-0410 | DOI: | 10.1186/1754-0410-3-6 | metadata.dc.identifier.url: | http://www.physmathcentral.com/1754-0410/3/6 |
