TL;DR: In this article, the authors used 1.09 x 10(9) J/psi events collected by the BESIII experiment in 2012, and observed a significant abrupt change in the slope of the eta'pi(+)pi(-) invariant mass distribution at the proton-antiproton (p (p) over bar) mass threshold.

TL;DR: In this article, a study of the trigger performance and comparisons with simulations show that these changes resulted in event selection efficiencies of > 98% for this period, meeting and in some cases exceeding the performance of similar triggers in earlier run periods, while at the same time keeping the necessary bandwidth within acceptable limits.

TL;DR: In this paper, the amplitude analysis for gamma chi(c1) and gamma chi (c1)-π(π(1.1400) was performed with the BESIII detector, and a significant nonzero a(0) (980) coupling to the eta'pi channel was measured.

TL;DR: The resonant substructure of the ϒ(11020)→h_{b}(nP)π^{+}π^{-} transitions is studied and evidence that they proceed entirely via the intermediate isovector states Z_{ b}(10610) and Z(10650) is found.

Abstract: We report on a comprehensive all-sky search for periodic gravitational waves in the frequency band 100-1500 Hz and with a frequency time derivative in the range of $[-1.18, +1.00]\times 10^{-8}$ Hz/s. Such a signal could be produced by a nearby spinning and slightly non-axisymmetric isolated neutron star in our galaxy. This search uses the data from the Initial LIGO sixth science run and covers a larger parameter space with respect to any past search. A Loosely Coherent detection pipeline was applied to follow up weak outliers in both Gaussian (95% recovery rate) and non-Gaussian (75% recovery rate) bands. No gravitational wave signals were observed, and upper limits were placed on their strength. Our smallest upper limit on worst-case (linearly polarized) strain amplitude $h_0$ is ${9.7}\times 10^{-25}$ near 169 Hz, while at the high end of our frequency range we achieve a worst-case upper limit of ${5.5}\times 10^{-24}$. Both cases refer to all sky locations and entire range of frequency derivative values.
