Abstract
New and recent results from the programme of studies in electroweak physics with open beauty performed by the ATLAS experiment are presented. Flavour-Changing-Neutral-Current (FCNC) processes are sensitive to New Physics contributions, in particular through additional electroweak loop amplitudes.
The angular analysis of the decay of Bd→K∗μμ for a number of angular coefficients are measured as a function of the invariant mass squared of the di-muon system for data collected by the ATLAS experiment at a centre-of-mass energy √s = 8 TeV.
A comparison is made to theoretical predictions, including for the observable P′5, for which there has been recent tension between theory and experiments.
