Observation of B c + → D h + h − Decays

R. Aaij, A. S. W. Abdelmotteleb, Carlos Abellán Beteta, C. Abellán Beteta et autres

Searches are presented for B_{c}^{+}→Dh^{+}h^{-} decays, where D is a charmed meson and h^{±} is a charged pion or kaon, using pp collision data collected by the LHCb experiment corresponding to an integrated luminosity of 9 fb^{-1}. The decays B_{c}^{+}→D^{+}K^{+}π^{-}, B_{c}^{+}→D^{*+}K^{+}π^{-}, and …

Search for $D^{*}(2007)^0\toμ^+μ^-$ in $B^-\toπ^-μ^+μ^-$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb, C. Abellán Beteta et autres

The very rare $D^{*}(2007)^0\toμ^+μ^-$ decay is searched for by analysing $B^-\toπ^-μ^+μ^-$ decays. The analysis uses a sample of beauty mesons produced in proton-proton collisions collected with the LHCb detector between 2011 and 2018, corresponding to an integrated luminosity of 9 fb$^{-1}$. The …

Search for the rare decay $D^0 \to \mu^+ \mu^-$

R. Aaij, C. Abellán Beteta, B. Adeva, M. Adinolfi et autres

A search for the rare decay $D^0 \to \mu^+ \mu^-$is performed using a data sample, corresponding to an integrated luminosity of 0.9 fb$^{-1}$, of $pp$ collisions collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The observed number of …
