First measurement of the absolute branching fraction of Λ →pμ- ν ¯ μ
M. Ablikim; M.N, Achasov; P. Adlarson; S. Ahmed; M. Albrecht; Kolcu, Onur Bugra; Cetin, Serkant Ali (American Physical Society, 2021)The absolute branching fraction of Λ→pμ−¯νμ is reported for the first time based on an e+e− annihilation sample of 10×109 J/ψ events collected with the BESIII detector at √s=3.097 GeV. The branching fraction is determined ... -
