2009-07-27T15:30:00 2009-07-27T15:50:00 00:20 “ B-CP anomalies, “4th” generation and the LHC Abstract Although the CKM-paradigm works approximately to O(20%), there are by now several indications that suggest the need for beyond the Standard Model CP-odd phase(s). The value of sin 2β measured via the goldplated (tree) mode, B → ψK s is smaller than the value deduced by using improved lattice matrix elements. The value of sin 2β measured via ‘penguin-dominated’ (loop) decays tends to be even smaller still. There is also a rather large difference between the direct CP asymmetries in → K − π + and B − → K − π 0 that is rather difficult to understand. Also recently, CDF and D0 are finding about a signal of CP asymmetry B s → ψϕ. If true, this would be consistent with the indications of new CP-phase in penguin b → s transitions seen at B-factories. We emphasize that the data are quite suggestive of a fourth family with m_ t' in the range of 400–600 GeV as perhaps the simplest BSM candidate which ‘naturally’ explains the data. This picture leads to significant repercussions for the LHC which will be explored. slides doc http://indico.cern.ch/images/word.png word file ppt http://indico.cern.ch/images/powerpoint.png powerpoint file pdf http://indico.cern.ch/images/pdf_small.png pdf file odt http://indico.cern.ch/images/writer.png writer file odp http://indico.cern.ch/images/impress.png presentation file ods http://indico.cern.ch/images/calc.png spreadsheet file other http://indico.cern.ch/images/file_small.png unknown type file link http://indico.cern.ch/images/link.png link 2013-05-23 2013-05-24
