Observation of an Altered $a_{0}(980)$ Line-shape in $D^{+} \rightarrow π^{+}ηη$ due to the Triangle Loop Rescattering Effect

BESIII Collaboration, Mikhail N. Achasov, P. Adlarson, X. C. Ai et autres

Using 20.3~${\rm fb}^{-1}$ of $e^{+}e^{-}$ collision data taken with the BESIII detector at the center-of-mass energy 3.773~GeV, we report the first amplitude analysis of the hadronic decay $D^{+} \rightarrow π^{+}ηη$. The intermediate process $D^{+} \to a_{0}(980)^{+}η, a_{0}(980)^{+} \to π^{+}η$ is observed and …

Amplitude analysis of $ψ(3686)\to γK_S^0 K_S^0 $

BESIII Collaboration, M. N. Achasov, P. Adlarson, X. Ai et autres

Using $(2712\pm14)\times10^6$ $ψ(3686)$ events collected with the BESIII detector, we perform the first amplitude analysis of the radiative decay $ψ(3686)\to γK_S^0 K_S^0$ within the mass region $M_{K_S^0 K_S^0 }<2.8$ GeV/$c^2$. Employing a one-channel K-matrix approach for the description of the dynamics of …

Search for the rare decay $J/ψ\to γD^0+c.c.$ at BESIII

BESIII Collaboration, Mikhail N. Achasov, P. Adlarson, O. Afedulidis et autres

Using $(10087\pm44)\times10^6J/ψ$ events collected with the BESIII detector, we search for the rare decay $J/ψ\to γD^0+c.c.$ for the first time. No obvious signal is observed and the upper limit on the branching fraction is determined to be ${\cal B}(J/ψ\to γD^{0}+c.c.)< 9.1 \times …

Observation of $η_{c}(2S) \to K^{+}K^{-}η$

BESIII Collaboration, Mikhail N. Achasov, P. Adlarson, O. Afedulidis et autres

By analyzing $(27.12 \pm 0.14)\times10^{8}$ $ψ(3686)$ events accumulated with the BESIII detector, the decay $η_{c}(2S) \to K^{+} K^{-} η$ is observed for the first time with a significance of $6.2σ$ after considering systematic uncertainties. The product of the branching fractions of $ψ(3686) …

Observation of $D^{+}\to K_{S}^{0}a_{0}(980)^{+}$ in the amplitude analysis of $D^{+} \to K_{S}^{0}π^+η$

BESIII Collaboration, M. N. Achasov, P. Adlarson, O. Afedulidis et autres

We perform for the first time an amplitude analysis of the decay $D^{+}\to K_{S}^{0}π^+η$ and report the observation of the decay $D^{+}\to K_{S}^{0}a_{0}(980)^{+}$ using 2.93 fb$^{-1}$ of $e^+e^-$ collision data taken at a center-of-mass energy of 3.773 GeV with the BESIII detector. …

Determination of U-spin breaking parameters with an amplitude analysis of the decay $D^0 \to K_{\rm L}^0π^+π^-$

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

We present a study of the resonant structure of the decay $D^0 \to K_{\rm L}^0π^+π^-$, using quantum-correlated $D^0\bar{D}^0$ data produced at $\sqrt{s}=3.773$ GeV. The data sample was collected by the BESIII experiment and corresponds to an integrated luminosity of $2.93$ fb$^{-1}$. This …
