Study of the decay Ds+→π+π+π−η and observation of the W -annihilation decay Ds+→a0(980)+ρ0

Mikhail N. Achasov, P. Adlarson, S. Ahmed, M. Albrecht et autres

The decay ${D}_{s}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\ensuremath{\eta}$ is observed for the first time, using ${e}^{+}{e}^{\ensuremath{-}}$ collision data corresponding to an integrated luminosity of $6.32\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, collected by the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV. The absolute branching fraction for this decay …

Observation of the doubly Cabibbo-Suppressed decays $D^+\to K^+π^0π^0$ and $D^+\to K^+π^0η$

BESIII Collaboration, Mikhail N. Achasov, P. Adlarson, S. N. Ahmed et autres

By analyzing $e^+e^-$ annihilation data corresponding to an integrated luminosity of $2.93\,\rm fb^{-1}$ collected at the center-of-mass energy of 3.773\,GeV with the BESIII detector, we report the first observations of the doubly Cabibbo-suppressed decays $D^+\to K^+π^0π^0$ and $D^+\to K^+π^0η$. The branching fractions …
