Abstract

Searches for the rare hadronic decays B0→pp¯pp¯ and Bs0→pp¯pp¯ are performed using proton-proton collision data recorded by the LHCb experiment and corresponding to an integrated luminosity of 9 fb-1. Significances of 9.3σ and 4.0σ, including statistical and systematic uncertainties, are obtained for the B0→pp¯pp¯ and Bs0→pp¯pp¯ signals, respectively. The branching fractions are measured relative to the topologically similar normalization decays B0→J/ψ(→pp¯)K∗0(→K+π-) and Bs0→J/ψ(→pp¯)⁢φ(→K+K-). The branching fractions are measured to be B(B0→pp¯pp¯)=(2.2±0.4±0.1±0.1)×10-8 and B(Bs0→pp¯pp¯)=(2.3±1.0±0.2±0.1)×10-8. In these measurements, the first uncertainty is statistical, the second is systematic, and the third one is due to the external branching fraction of the normalization channel.

Significances of 9.3σ and 4.0σ, including statistical and systematic uncertainties, are obtained for the B0→pp¯pp¯ and Bs0→pp¯pp¯ signals, respectively. The branching fractions are measured relative to the topologically similar normalization decays B0→J/ψ(→pp¯)K∗0(→K+π-) and Bs0→J/ψ(→pp¯)⁢φ(→K+K-). The branching fractions are measured to be B(B0→pp¯pp¯)=(2.2±0.4±0.1±0.1)×10-8 and B(Bs0→pp¯pp¯)=(2.3±1.0±0.2±0.1)×10-8. In these measurements, the first uncertainty is statistical, the second is systematic, and the third one is due to the external branching fraction of the normalization channel.
