First Determination of the Spin-Parity of Ξ_{c}(3055)^{+,0} Baryons.

The Ξ_{b}^{0(-)}→Ξ_{c}(3055)^{+(0)}(→D^{+(0)}Λ)π^{-} decay chains are observed, and the spin-parity of Ξ_{c}(3055)^{+(0)} baryons is determined for the first time. The measurement is performed using proton-proton collision data at a center-of-mass energy of sqrt[s]=13  TeV, corresponding to an integrated luminosity of 5.4  fb^{-1}, recorded by the LHCb experiment between 2016 and 2018.

Cycling among people experiencing socio-economic disadvantage: a scoping review protocol.

Introduction: Active mobility, such as walking, wheeling, and cycling, is a low-carbon transport mode and a source of physical activity. Cycling, as a form of active mobility, is associated with physical and mental health benefits, transport cost savings, and improved air quality. During the transition to sustainable mobility, equitable outcomes depend on opportunities for active mobility reaching across our societies.

Measurement of the Branching Fraction Ratios R(D^{+}) and R(D^{*+}) Using Muonic τ Decays.

The branching fraction ratios of B[over ¯]^{0}→D^{+}τ^{-}ν[over ¯]_{τ} and B[over ¯]^{0}→D^{*+}τ^{-}ν[over ¯]_{τ} decays are measured with respect to their muonic counterparts, using a data sample corresponding to an integrated luminosity of 2.0  fb^{-1} collected by the LHCb experiment in proton-proton collisions at sqrt[s]=13  TeV. The reconstructed final states are formed by combining D^{+} mesons with τ^{-}→μ^{-}ν[over ¯]_{μ}ν_{τ} candidates, where the D^{+} is reconstructed via the D^{+}→K^{-}π^{+}π^{+} decay.

Observation of Exotic J/ψϕ Resonant Structure in Diffractive Processes in Proton-Proton Collisions.

The first study of J/ψϕ production in diffractive processes in proton-proton collisions is presented. The study is based on an LHCb dataset recorded at center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5  fb^{-1}. The data disfavor a nonresonant J/ψϕ production but are consistent with a resonant model including several resonant states observed previously only in B^{+}→J/ψϕK^{+} decays.
