dc.description.abstractThe D-s(+) -> K+K-mu (+)nu(mu) decay is studied based on 7.33 fb(-1)ofe+e-collisiondata collected with the BESIII detector at center-of-mass energies in the range from 4.128to 4.226 GeV. The absolute branching fraction is measured as B(D+s ->phi mu+nu mu) = (2.25 +/- 0.09 +/- 0.07)x10-2, the most precise measurement to date. Combining with the world average of B(D+s ->phi e+nu e), the ratio of the branching fractions obtained is B(D+s ->phi mu+nu mu)B(D+s ->phi e+nu e)=0.94 +/- 0.08, in agreement with lepton universality. By performing a partial wave analysis, the hadronic form factor ratios atq2= 0are extracted, finding rV=V(0)A1(0)= 1.58 +/- 0.17 +/- 0.02andr2=A2(0)A1(0)= 0.71 +/- 0.14 +/- 0.02, where the first uncertainties are statistical and the second are systematic. No significant S-wave contribution fromf0(980)-> K+K-is found. The upper limitB(D+s -> f0(980)mu+nu mu)B(f0(980)-> K+K-)<5.45x10-4is set at 90% credibility levelen_US
