A precise measurement of the $B^{0}$ meson oscillation frequency

LHCb collaboration, R. Aaij, C. Abellán Beteta +730

The oscillation frequency, $Δ m_{d}$ , of $B^{0}$ mesons is measured using semileptonic decays with a $D^{-}$ or $D^{*-}$ meson in the final state, in a data sample of $pp$ collisions coll…
