A comprehensive analysis of the $B^0\to K^{*0}μ^+μ^-$ decay

Roel Aaij, Ahmed Sameh Wagih Abdelmotteleb, Carlos Abellan Beteta, Fernando Jesus Abudinén et autres

An analysis of the $B^{0}\rightarrow K^{*0}(\to K^+ π^-)μ^{+}μ^{-}$ decay is presented using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 8.4 fb$^{-1}$. The full set of $CP$-averaged and $CP$-asymmetric angular observables is determined in bins of …

Search for heavy neutral leptons in B-meson decays

Roel Aaij, Ahmed Sameh Wagih Abdelmotteleb, Carlos Abellan Beteta, Fernando Jesus Abudinén et autres

A search for long-lived heavy neutral leptons produced in B-meson decays and decaying to a μ±π∓ final state is performed with data collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity …
