Novel approach to measure the leptonic eta(')->mu+mu- decays via charmed meson decays

Nguyen Thu Huong, Emi Kou, Benoit Viaud

In this article, we propose a novel approach to measure the branching ratios of the leptonic eta(')-> mu+mu- decays by using charmed meson decays, namely, D+(s)->pi+ eta(')(->mu+mu…
