Measurement of the absolute branching fraction for Λc + → Λμ+νμ

We report the first measurement of the absolute branching fraction for View the MathML sourceΛc+→Λμ+νμ. This measurement is based on a sample of e+e−e+e− annihilation data produced at a center-of-mass energy View the MathML sources=4.6 GeV, collected with the BESIII detector at the BEPCII storage ri...
