Study of $η\rightarrowπ^+π^-l^+l^-$

BESIII Collaboration, M. Ablikim, М. Н. Ачасов, P. Adlarson et autres

Using a sample of $(10087\pm44)\times10^{6}$ $J/ψ$ events accumulated with the BESIII detector, we analyze the decays $η\rightarrowπ^+π^-l^+l^-$ ($l=e$ or $μ$) via the process $J/ψ\rightarrowγη$. The branching fraction of $η\rightarrowπ^+π^-e^+e^-$ is measured to be $\mathcal{B}(η\rightarrowπ^+π^-e^+e^-)=(3.07\pm0.12_{\rm{stat.}}\pm0.19_{\rm{syst.}}) \times10^{-4}$. No signal events are observed for the …

Partial wave analyses of $ψ(3686)\to p\bar{p}π^0$ and $ψ(3686)\to p\bar{p}η$

BESIII Collaboration, M. Ablikim, М. Н. Ачасов, P. Adlarson et autres

Using a sample of $(2712\pm14)\times10^6$ $ψ(3686)$ events collected with the BESIII detector, we perform partial wave analyses of the decays $ψ(3686)\to p\bar{p}π^0$ and $ψ(3686)\to p\bar{p}η$. The branching fractions of $ψ(3686)\to p\bar{p}π^0$ and $ψ(3686)\to p\bar{p}η$ are determined to be $(133.9\pm11.2\pm2.3)\times10^{-6}$ or $(183.7\pm13.7\pm3.2)\times10^{-6}$ and …

Learning Nonholonomic Dynamics with Constraint Discovery

B. L. Wang, Anthony M. Bloch

We consider learning nonholonomic dynamical systems while discovering the constraints, and describe in detail the case of the rolling disk. A nonholonomic system is a system subject to nonholonomic constraints. Unlike holonomic constraints, nonholonomic constraints do not define a sub-manifold on the …

Observation of $χ_{cJ}\to p \bar p K^0_S K^- π^+ + c.c.$

BESIII Collaboration, M. Ablikim, М. Н. Ачасов, P. Adlarson et autres

By analyzing $(27.12\pm0.14)\times10^8$ $ψ(3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decays of $χ_{cJ} \to p \bar{p} K^0_S K^- π^+ +c.c.(J=0, 1, 2)$ are observed for the first time with statistical significances greater than $10σ$. The branching …

Measurements of the $CP$-even fractions of $D^0\toπ^{+}π^{-}π^{0}$ and $D^0\to K^{+}K^{-}π^{0}$ at BESIII

BESIII Collaboration, M. Ablikim, М. Н. Ачасов, P. Adlarson et autres

The $CP$-even fractions ($F_{+}$) of the decays $D^0\toπ^{+}π^{-}π^{0}$ and $D^0\to K^{+}K^{-}π^{0}$ are measured with a quantum-correlated $ψ(3770)\to D\bar{D}$ data sample collected by the BESIII experiment corresponding to an integrated luminosity of 7.93 $\mathrm{fb}^{-1}$. The results are $F_{+}^{π^{+}π^{-}π^{0}}=0.9406\pm0.0036\pm0.0021$ and $F_{+}^{K^{+}K^{-}π^{0}}=0.631\pm0.014\pm0.011$, where the first …

BESIII Collaboration, M. Ablikim, М. Н. Ачасов, P. Adlarson et autres

Using a data sample of $e^+e^-$ collisions corresponding to an integrated luminosity of 7.93 $\rm fb^{-1}$ collected with the BESIII detector at the center-of-mass energy 3.773~GeV, we perform the first amplitude analysis of the decay $D^{+} \to K_{S}^{0} K_{S}^{0} π^{+}$. The absolute …

Model-independent determination of the strong-phase difference between $D^0$ and $\bar{D}^0 \to π^+π^-π^+π^-$ decays

BESIII Collaboration, M. Ablikim, М. Н. Ачасов, P. Adlarson et autres

Measurements of the strong-phase difference between $D^0$ and $\bar{D}^0\toπ^+π^-π^+π^-$ are performed in bins of phase space. The study exploits a sample of quantum-correlated $D\bar{D}$ mesons collected by the BESIII experiment in $e^+e^-$ collisions at a center-of-mass energy of 3.773~GeV, corresponding to an …

Analysis of the dynamics of the decay $D^{+}\to K_{S}^{0} π^{0} e^{+}ν_{e}$

BESIII Collaboration, M. Ablikim, М. Н. Ачасов, P. Adlarson et autres

The branching fraction of $D^+\to K_{S}^{0} π^{0}e^+ν_e$ is measured for the first time using $7.93~\mathrm{fb}^{-1}$ of $e^+e^-$ annihilation data collected at the center-of-mass energy $\sqrt{s}=3.773$~GeV with the BESIII detector operating at the BEPCII collider, and is determined to be ${\mathcal B}$($D^+\to K_S^0π^0e^+ν_e$) …

Based on $6.1~\mathrm{fb}^{-1}$ of $e^+e^-$ annihilation data collected at center-of-mass energies from 4.600 to 4.843 GeV with the BESIII detector at the BEPCII collider, a partial wave analysis of $Λ_c^+\toΛπ^+η$ is performed, and branching fractions and decay asymmetry parameters of intermediate processes …

We perform the first amplitude analysis of $D^+_s \to π^+π^+π^-π^0$ decays, based on data samples of electron-positron collisions recorded with the BESIII detector at center-of-mass energies between 4.128 and 4.226~GeV, corresponding to an integrated luminosity of 7.33~fb$^{-1}$.
