Title: Improved measurement of the absolute branching fraction of $$D^{+}\rightarrow \bar{K}^0 \mu ^{+}\nu _{\mu }$$

Abstract

Here, by analyzing 2.93 fb-1 of data collected at √s = 3.773 GeV with the BESIII detector, we measure the absolute branching fraction B(D+ → K¯0μ+νμ) = (8.72 ± 0.07stat. ± 0.18sys.)%, which is consistent with previous measurements within uncertainties but with significantly improved precision. Combining the Particle Data Group values of B(D0 → K-μ+νμ), B(D+ → K¯0e+νe), and the lifetimes of the D0 and D+ mesons with the value of B(D+ → K¯0μ+νμ) measured in this work, we determine the following ratios of partial widths: Γ(D0 → K-μ+νμ)/Γ(D+ → K¯0μ+νμ) = 0.963 ± 0.044 and Γ(D+ → K¯0μ+νμ)/Γ(D+ → K¯0e+νe) = 0.988 ± 0.033.

abstractNote = {Here, by analyzing 2.93 fb-1 of data collected at √s = 3.773 GeV with the BESIII detector, we measure the absolute branching fraction B(D+ → K¯0μ+νμ) = (8.72 ± 0.07stat. ± 0.18sys.)%, which is consistent with previous measurements within uncertainties but with significantly improved precision. Combining the Particle Data Group values of B(D0 → K-μ+νμ), B(D+ → K¯0e+νe), and the lifetimes of the D0 and D+ mesons with the value of B(D+ → K¯0μ+νμ) measured in this work, we determine the following ratios of partial widths: Γ(D0 → K-μ+νμ)/Γ(D+ → K¯0μ+νμ) = 0.963 ± 0.044 and Γ(D+ → K¯0μ+νμ)/Γ(D+ → K¯0e+νe) = 0.988 ± 0.033.},
