${{\mathit \rho}{(770)}}$ $\rightarrow$ ${{\mathit e}^{+}}{{\mathit e}^{-}}$   Decay Mode Summary INSPIRE   PDGID:
M009.4
Mode (*) Fraction ($\Gamma_i$ / $\Gamma$) Scale Factor/
Conf. Level		 P(MeV/c)  
$\Gamma_{13}$ ${{\mathit \rho}{(770)}}$ $\rightarrow$ ${{\mathit e}^{+}}{{\mathit e}^{-}}$ ($4.72$ $\pm0.05$) $ \times 10^{-5}$ 388
Category: ${{\mathit \rho}{(770)}^{0}}$ decays
Note: The ${{\mathit \omega}}{{\mathit \rho}}$ interference is then due to ${{\mathit \omega}}{{\mathit \rho}}$ mixing only, and is expected to be small. If ${{\mathit e}}{{\mathit \mu}}$ universality holds, $\Gamma\mathrm {( {{\mathit \rho}^{0}} \rightarrow {{\mathit \mu}^{+}} {{\mathit \mu}^{-}} )}$ = $\Gamma\mathrm {( {{\mathit \rho}^{0}} \rightarrow {{\mathit e}^{+}} {{\mathit e}^{-}} )}{\times }$ 0.99785.
