Study of $η - η^{'}$ mixing from measurement of $B_{(s)}^{0} \to J / ψ η^{(')}$ ~decay rates

LHCb collaboration, R. Aaij, B. Adeva +701

A study of $B^{0}$ ~and $B_{s}^{0}$ meson decays into $J / ψ η$ ~and $J / ψ η^{'}$ final states is performed using a data set of proton-proton collisions at centre-of-mass energies of 7 and…

Observation of the rare $B_{s}^{0} \to μ^{+} μ^{-}$ decay from the combined analysis of CMS and LHCb data

The CMS, LHCb Collaborations, : +2807

A joint measurement is presented of the branching fractions $B_{s}^{0} \to μ^{+} μ^{-}$ and $B^{0} \to μ^{+} μ^{-}$ in proton-proton collisions at the LHC by the CMS and LHCb experiments. The data sam…

Interplay between antiferrodistortive, ferroelectric and superconducting instabilities in Sr_{1-x}Ca_{x}$TiO_{3-δ}

B. S. de Lima, M. S. da Luz, F. S. Oliveira +11

SrTiO $_{3}$ undergoes a cubic-to-tetragonal phase transition at 105K. This antiferrodistortive transition is believed to be in competition with incipient ferroelectricity. Substitu…
