New Measurements of the D+ to K*munu/k2pi and Ds to phimunu/phipi Branching ratios
The Focus Collaboration
TL;DR
This paper reports new measurements of specific charm meson semileptonic decay branching ratios using data from the FOCUS experiment, providing more precise values that include interference effects.
Contribution
The study presents the first measurements of these branching ratios with improved precision and accounts for s-wave interference effects.
Findings
D+ to K*munu/k2pi = 0.602 +/- 0.010 +/- 0.021
Ds to phimunu/phipi = 0.54 +/- 0.033 +/- 0.048
Results include interference effects
Abstract
Using a large sample of charm semileptonic decays collected by the FOCUS photoproduction experiment at Fermilab, we present new measurements of two semileptonic branching ratios. We obtain values of D+ to K*munu/k2pi = 0.602 +/- 0.010 +/- 0.021 and Ds to phimunu/phipi = 0.54 +/- 0.033 +/- 0.048. Our result D+ result includes the effects of s-wave interference.
