Measurement of the absolute branching fraction and decay asymmetry of Λ→nγ
Ablikim, M; Achasov, M. N.; Adlarson, Patrik; Albrecht, Malte; Amoroso A.; Cetin, Serkant Ali; Kolcu, Onur Buğra (American Physical Society, 2022)The radiative hyperon decay Λ→nγ is studied using (10087±44)×10^{6} J/ψ events collected with the BESIII detector operating at BEPCII. The absolute branching fraction of the decay Λ→nγ is determined to be (0.832±0.038_{s ... -
