Angular analysis of the B${}^0$ $\to$ K${}^{\ast }$(892)${}^0\hat{I}{¼}^{+}\hat{I}{¼}^{-}$ decay in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

A full set of optimized observables is measured in an angular analysis of the decay B${}^0$ $\to$ K${}^{\ast }$(892)${}^0\hat{I}{¼}^{+}\hat{I}{¼}^{-}$ using a sample of proton-proton collisions at $\sqrt{s}$ = 13…
