Observation of the semileptonic decay B+ → pp[bar]μ+νμ
The Cabibbo-suppressed semileptonic decay B+→pp̄μ+νμ is observed for the first time using a sample of pp collisions corresponding to an integrated luminosity of 1.0, 2.0 and 1.7 fb−1 at centre-of-mass energies of 7, 8 and 13 TeV, respectively. The differential branching fraction is measured as a fu...

| 520 | |a The Cabibbo-suppressed semileptonic decay B+→pp̄μ+νμ is observed for the first time using a sample of pp collisions corresponding to an integrated luminosity of 1.0, 2.0 and 1.7 fb−1 at centre-of-mass energies of 7, 8 and 13 TeV, respectively. The differential branching fraction is measured as a function of the $$ p\overline{p} $$ invariant mass using the decay mode B+→ J/ψK+ for normalisation. | ||
