Measurement of $f_{s} / f_{u}$ variation with proton-proton collision energy and $B$ -meson kinematics

LHCb collaboration, R. Aaij, C. Abellán Beteta +903

The ratio of the $B_{s}^{0}$ and $B^{+}$ fragmentation fractions $f_{s}$ and $f_{u}$ is studied with $B_{s}^{0} \to J / ψ ϕ$ and $B^+\to\mathrm{J…

Observation of several sources of $C P$ violation in $B^{+} \to π^{+} π^{+} π^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +868

Observations are reported of different sources of $C P$ violation from an amplitude analysis of $B^{+} \to π^{+} π^{+} π^{-}$ decays, based on a data sample corresponding to an integrated l…

Observation of new resonances in the $Λ_{b}^{0} π^{+} π^{-}$ system

LHCb collaboration, R. Aaij, C. Abellán Beteta +910

We report the observation of a new structure in the $Λ_{b}^{0} π^{+} π^{-}$ spectrum using the full LHCb data set of $pp$ collisions, corresponding to an integrated luminosity of $9\,\mathr…

Dependence of atmospheric muon flux on seawater depth measured with the first KM3NeT detection units

KM3NeT Collaboration, M. Ageron, S. Aiello +262

KM3NeT is a research infrastructure located in the Mediterranean Sea, that will consist of two deep-sea Cherenkov neutrino detectors. With one detector (ARCA), the KM3NeT Collabora…

Amplitude analysis of $B^{\pm} \to π^{\pm} K^{+} K^{-}$ decays

LHCb Collaboration, R. Aaij, C. Abellán Beteta +842

The first amplitude analysis of the $B^{\pm} \to π^{\pm} K^{+} K^{-}$ decay is reported based on a data sample corresponding to an integrated luminosity of 3.0 fb $^{- 1}$ of $pp$ collisions…

Measurement of $C P$ -violating and mixing-induced observables in $B_{s}^{0} \to ϕ γ$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +859

A time-dependent analysis of the $B_{s}^{0} \to ϕ γ$ decay rate is performed to determine the $C P$ -violating observables $S_{ϕ γ}$ and $C_{ϕ γ}$ , and the mixing-induced observable $\mathc…
