Observations of the Cabibbo-Suppressed decays $Λ_{c}^{+}\to nπ^{+}π^{0}$, $nπ^{+}π^{-}π^{+}$ and the Cabibbo-Favored decay $Λ_{c}^{+}\to nK^{-}π^{+}π^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

Using electron-positron annihilation data samples corresponding to an integrated luminosity of 4.5 $\rm{{fb}^{-1}}$, collected by the BESIII detector in the energy region between $4600$ MeV and $4699$ MeV, we report the first observations of the Cabibbo-suppressed decays $Λ_c^+\to nπ^+π^0$, $Λ_c^+\to nπ^+π^-π^+$, and …

Measurement of the $C\!P$-even fraction of $D^{0}\toπ^{+}π^{-}π^{+}π^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

A measurement of the $C\!P$-even fraction of the decay $D^{0}\toπ^{+}π^{-}π^{+}π^{-}$ is performed with a quantum-correlated $ψ(3770)\to D\bar{D}$ data sample collected by the BESIII experiment, corresponding to an integrated luminosity of 2.93 $\textrm{fb}^{-1}$. Using a combination of $C\!P$ eigenstates, $D \to π^+π^-π^0$ and …

Measurement of the integrated luminosities of the data taken by BESIII at √ s = 3.650 and 3.773 GeV

M. N. Achasov, O. Albayrak, D. Ambrose, F. F. An et autres

Data sets were collected with the BESIII detector at the BEPCII collider at the center-of-mass energy of √ s = 3.650 GeV during May 2009 and at √ s = 3.773 GeV from January 2010 to May 2011. By analyzing the large …
