Abstract
A broad range of measurements involving B mesons are performed with the ATLAS experiment at the Large Hadron Collider, of which a selection is discussed in this note. This includes a measurement of the relative B±c to B± production cross section in pp collisions at a centre-of-mass energy √s of 8 TeV, as well as the latest results on the branching ratios of the rare decays B0s→μ+μ− and B0→μ+μ− using pp collisions recorded at √s= 7, 8 and 13 TeV. Furthermore, accurate measurements of mixing and CP violation in B0s→J/ψϕ decays are performed. The latest results on the CP violating phase ϕs and other parameters describing the decay obtained at √s= 7, 8 and 13 TeV are reported.
