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...

| 520 | 3 | |a 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 rings. The sample corresponds to an integrated luminosity of 567 pb−1567 pb−1. The branching fraction is determined to be View the MathML sourceB(Λc+→Λμ+νμ)=(3.49±0.46(stat)±0.27(syst))%. In addition, we calculate the ratio View the MathML sourceB(Λc+→Λμ+νμ)/B(Λc+→Λe+νe) to be 0.96±0.16(stat)±0.04(syst)0.96±0.16(stat)±0.04(syst). | |
