Analyzing $(448.1pm2.9)times10^6$ $psi(3686)$ events collected with the BESIII detector at the BEPCII collider, the $psi(3686)to omega K_{S}^{0}K_{S}^{0}$ decay is observed for the first time. The branching fraction for this decay is determined to be $mathcal{B}_{psi(3686)to omega K_{S}^{0}K^{0}_{S}}$=$(7.04pm0.39pm0.36)$$times10^{-5}$, where the first uncertainty is statistical and the second is systematic.

With $1.06times 10^8$ $psi(3686)$ events collected with the BESIII detector, the branching fraction of $psi(3686) to omega K^+ K^-$ is measured to be $(1.54 pm 0.04 pm 0.11) times 10^{-4}$. This is the most precise result to date, due to the largest $psi(3686)$ sample, improved signal reconstruction efficiency, good simulation of the detector performance, and a more accurate knowledge of the continuum contribution. Using the branching fraction of $J/psi to omega K^+ K^-$, the ratio $mathcal{B}(psi(3868) to K^+K^-) / mathcal{B}(J/psi to K^+K^-)$ is determined to be $(18.4 pm 3.7),%$. This constitutes a significantly improved test of the $12,%$ rule, with the uncertainty now dominated by the $J/psi$ branching fraction.
By analyzing $2.93 rm fb^{-1}$ of data taken at the $psi(3770)$ resonance peak with the BESIII detector, we measure the branching fractions for the hadronic decays $D^+to K^0_SK^0_S K^+$, $D^+to K^0_SK^0_S pi^+$, $D^0to K^0_S K^0_S$ and $D^0to K^0_SK ^0_SK^0_S$. They are determined to be ${mathcal B}(D^+to K^0_SK^0_SK^+)=(2.54 pm 0.05_{rm stat.} pm 0.12_{rm sys.})times 10^{-3}$, ${mathcal B}(D^+to K^0_SK^0_Spi^+)=(2.70 pm 0.05_{rm stat.} pm 0.12_{rm sys.})times 10^{-3}$, ${mathcal B}(D^0to K^0_SK^0_S)=(1.67 pm 0.11_{rm stat.} pm 0.11_{rm sys.})times 10^{-4}$ and ${mathcal B}(D^0to K^0_SK^0_SK^0_S)=(7.21 pm 0.33_{rm stat.} pm 0.44_{rm sys.})times 10^{-4}$, where the second one is measured for the first time and the others are measured with significantly improved precision over the previous measurements.
We report a study of the decay $D^0 to K^0_S K^0_S$ using 921~fb$^{-1}$ of data collected at or near the $Upsilon(4S)$ and $Upsilon(5S)$ resonances with the Belle detector at the KEKB asymmetric energy $e^+e^-$ collider. The measured time-integrated $CP$ asymmetry is $ A_{CP}(D^0 to K^0_S K^0_S) = (-0.02 pm 1.53 pm 0.02 pm 0.17) %$, and the branching fraction is $mathcal{B} (D^{0}rightarrow K_{S}^{0}K_{S}^{0})$ = (1.321 $pm$ 0.023 $pm$ 0.036 $pm$ 0.044) $times$ 10$^{-4}$, where the first uncertainty is statistical, the second is systematic, and the third is due to the normalization mode ($D^0 to K_S^0 pi^0$). These results are significantly more precise than previous measurements available for this mode. The $A_{CP}$ measurement is consistent with the standard model expectation.
Using a sample of 106 million $psi(3686)$ decays, the branching fractions of $psi(3686) to gamma chi_{c0}, psi(3686) to gamma chi_{c1}$, and $psi(3686) to gamma chi_{c2}$ are measured with improved precision to be $(9.389 pm 0.014 pm 0.332),%$, $(9.9 05 pm 0.011 pm 0.353),% $, and $(9.621 pm 0.013 pm 0.272),% $, respectively, where the first uncertainties are statistical and the second ones are systematic. The product branching fractions of $psi(3686) to gamma chi_{c1}, chi_{c1} to gamma J/psi$ and $psi(3686) to gamma chi_{c2}, chi_{c2} to gamma J/psi$ and the branching fractions of $chi_{c1} to gamma J/psi$ and $chi_{c2} to gamma J/psi$ are also presented.
Using 5.9~pb$^{-1}$ of $e^+e^-$ annihilation data collected at center-of-mass energies from 3.640 to 3.701 GeV with the BESIII detector at the BEPCII Collider, we measure the observed cross sections of $e^+e^-rightarrow K_{S}^{0} X$ (where $X= text{a nything}$). From a fit to these observed cross sections with the sum of continuum and $psi(3686)$ and $J/psi$ Breit-Wigner functions and considering initial state radiation and the BEPCII beam energy spread, we obtain for the first time the product of $psi(3686)$ leptonic width and inclusive decay branching fraction $Gamma^{ee}_{psi(3686)}mathcal B(psi(3686)rightarrow K_{S}^{0} X) = (373.8 pm 6.7 pm 20.0)$ eV, and assuming $Gamma^{ee}_{psi(3686)}$ is $(2.33 pm 0.04)$ keV from PDG value, we measure $mathcal B(psi(3686)rightarrow K_{S}^{0} X) = (16.04 pm 0.29 pm 0.90)%$, where the first uncertainty is statistical and the second is systematic.
