• William Sutcliffe

Lex Greeven gave a presentation for B->rho l nu untagged analysis. Utilising truthmatching, he found a large amount of fake leptons (2/3 of background). It appears a lepton momentum (in CM frame) cut of 1 GeV will help supress this.

Will indicated that summing up the rest of event could find a B providing info of other variables such as q^2, Mbc, Delta E etc. Will also mentioned to check lepton fakes after more of the known signal selection is applied and that if needed the fake component can be derived from data. Kevin asked the version of software (2-0-0-3) and MC sample.

Will suggested that the updated B->rholnu FFs of Markus Prim be used.
