Measurement of the ratio of branching fractions and difference in $C P$ asymmetries of the decays $B^{+} \to J / ψ π^{+}$ and $B^{+} \to J / ψ K^{+}$

LHCb collaboration, R. Aaij, B. Adeva +764

The ratio of branching fractions and the difference in $C P$ asymmetries of the decays $B^{+} \to J / ψ π^{+}$ and $B^{+} \to J / ψ K^{+}$ are measured using a data sample of $pp$ collisions collec…

Search for $C P$ violation in the phase space of $D^{0} \to π^{+} π^{-} π^{+} π^{-}$ decays

LHCb collaboration, R. Aaij, B. Adeva +769

A search for time-integrated $C P$ violation in the Cabibbo-suppressed decay $\mbox{$D^0\rightarrowπ^+π^-π^+π^-$}$ is performed using an unbinned, model-independent technique known…

Measurements of charm mixing and $C P$ violation using $D^{0} \to K^{\pm} π^{\mp}$ decays

LHCb collaboration, R. Aaij, B. Adeva +766

Measurements of charm mixing and $C P$ violation parameters from the decay-time-dependent ratio of $D^{0} \to K^{+} π^{-}$ to $D^{0} \to K^{-} π^{+}$ decay rates and the charge-conjugate…

Measurement of matter-antimatter differences in beauty baryon decays

LHCb collaboration, R. Aaij, B. Adeva +762

Differences in the behaviour of matter and antimatter have been observed in $K$ and $B$ meson decays, but not yet in any baryon decay. Such differences are associated with the non-…

First experimental study of photon polarization in radiative $B_{s}^{0}$ decays

LHCb collaboration, R. Aaij, B. Adeva +765

The polarization of photons produced in radiative $B_{s}^{0}$ decays is studied for the first time. The data are recorded by the LHCb experiment in $pp$ collisions corresponding to…

Search for structure in the $B_{s}^{0} π^{\pm}$ invariant mass spectrum

LHCb collaboration, R. Aaij, B. Adeva +761

The $B_{s}^{0} π^{\pm}$ invariant mass distribution is investigated in order to search for possible exotic meson states. The analysis is based on a data sample recorded with the LHCb dete…
