Precision measurements of branching fractions for and
M. Ablikim, M. N. Achasov, O. Albayrak +342
We present a precision study of the $\psip\toπ^0 J/ψ$ and decay modes. The measurements are obtained using events accumulated with the BESIII detector a…
Determination of the number of event at BESIII
M. Ablikim, M. N. Achasov, D. J. Ambrose
The number of $\psp$ events accumulated by the BESIII experiment from March 3 through April 14, 2009, is determined by counting inclusive hadronic events. The result is $106.41\tim…
Search for and Invisible Decays in and
M. Ablikim, M. N. Achasov, O. Albayrak +340
Using a sample of decays collected with the BESIII detector at BEPCII, searches for invisible decays of and in and $ϕη…
First observation of the isospin violating decay
M. Ablikim, M. N. Achasov, D. J. Ambrose +353
Using a sample of events collected with the BESIII detector, we present results of a study of and report the first observ…
Experimental study of psi' decays to K+K- pi^0 and K+K- eta
M. Ablikim, M. N. Achasov, D. J. Ambrose +353
Using $\psip$ events accumulated with the BESIII detector at the BEPCII collider, we present measurements of the branching fractions for psi' decays…
Two-photon widths of the states and helicity analysis for $χ_{c2}\arγγ$}
BESIII Collaboration, M. Ablikim, M. N. Achasov +354
Based on a data sample of 106 M events collected with the BESIII detector, the decays $ψ^{\prime}\arγχ_{c0, 2}$,$χ_{c0, 2}\arγγ$ are studied to determine the two-photo…
A side-by-side comparison of Daya Bay antineutrino detectors
Daya Bay Collaboration, F. P. An, Q. An +237
The Daya Bay Reactor Neutrino Experiment is designed to determine precisely the neutrino mixing angle with a sensitivity better than 0.01 in the parameter sin a…
