The branching ratio $ω \to π^{+} π^{-}$ revisited

C. Hanhart, S. Holz, B. Kubis +3

We analyze the most recent data for the pion vector form factor in the timelike region, employing a model-independent approach based on dispersion theory. We confirm earlier observ…

$η_{c} \to l^{+} l^{-}$ and $χ_{c 0} \to l^{+} l^{-}$ decays revisited

N. Kivel, A. Kupsc

We present a calculation of $η_{c} \to l^{+} l^{-}$ and $χ_{c 0} \to l^{+} l^{-}$ decay widths. The amplitudes are computed within leading-order approximation using NRQC…
