Search for resonance-enhanced 𝐶⁢𝑃 and angular asymmetries in the [Lambda]+ 𝑐 →𝑝⁢[mu]+[mu]- decay at LHCb

The first measurement of the 𝐶⁢𝑃 asymmetry of the decay rate (𝐴𝐶⁢𝑃) and the 𝐶⁢𝑃 average (Σ⁢𝐴FB) and 𝐶⁢𝑃 asymmetry (Δ⁢𝐴FB) of the forward-backward asymmetry in the muon system of Λ+𝑐 →𝑝⁢𝜇+⁢𝜇− decays is reported. The measurement is performed using a data sample of proton-proton collisions, recorded by...
