Measurement of the form-factor ratios for D_s^+ -> phi ell^+ nu_ell
Fermilab E791 Collaboration, E. M. Aitala, S. Amato
We have measured the form factor ratios r_V = V(0)/A_1(0) and r_2 = A_2(0)/A_1(0) for the decay D_s^+ -> phi ell^+ nu_ell, phi -> K^+ K^-, using data from charm hadroproduction exp…
Measurement of the Ds Lifetime
Fermilab E791 Collaboration, E. M. Aitala
We report the results of a precise measurement of the Ds meson lifetime based on 1662 +/- 56 fully reconstructed Ds -> phi pi decays, from the charm hadroproduction experiment E791…
Measurement of the form-factor ratios for D+ --> K* l nu
E. M. Aitala et al, E791 Collaboration
The form factor ratios rv=V(0)/A1(0), r2=A2(0)/A1(0) and r3=A3(0)/A1(0) in the decay D+ --> K* l nu, K* -->K-pi+ have been measured using data from charm hadroproduction experiment…
