Hi, I am working on D 0 →K+ K− for my school project. I looked for any similar subjects and essays, i could not find this specific decay, i could write the form factors and also effective hamiltonian by myself but unfortunately i have problem writing the equations for LCDA ( light cone...
thanks for your help, do you know how many graphs does the decay of D→KK meson have? i would be grateful if you know a source which i can find more information about decay of D→KK meson graph.
