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

Mostrar otras versiones (1)

The oscillation frequency of $B^0$ mesons is measured using semileptonic decays with a charged $D$ or $D^*$ meson in the final state, on a data sample collected by the LHCb detector corresponding to an integrated luminosity of 3 fb$^{-1}$ of $pp$ collisions. A combination of the two decay m...

description The oscillation frequency of $B^0$ mesons is measured using semileptonic decays with a charged $D$ or $D^*$ meson in the final state, on a data sample collected by the LHCb detector corresponding to an integrated luminosity of 3 fb$^{-1}$ of $pp$ collisions. A combination of the two decay modes gives $\Delta m_d = (503.6 \pm 2.0 \pm 1.3)$ ns$^{-1}$ , where the first uncertainty is statistical and the second systematic. This is the most precise single measurement of this parameter. It is compatible with the current world average and has comparable precision
