TL;DR: In this article, a measurement of the CP-violating weak mixing phase phi(s) using the decay (B) over bar (0)(s) -> Ds+Ds- in a data sample corresponding to 3.0 fb(-1) of integrated luminosity collected with the LHCb detector in pp collisions at center-of-mass energies of 7 and 8 TeV.

TL;DR: In this paper, the double differential cross-sections of prompt and non-prompt meson production were measured as a function of the J/ψ transverse momentum and rapidity in the nucleon-nucleon center-of-mass frame.

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.

TL;DR: In this article, the first low frequency all-sky search of continuous gravitational wave signals was conducted on Virgo VSR2 and VSR4 data and the results of the search covered the full sky, a frequency range between 20 and 128 Hz with a range of spin-down between -1.0×10-10 and +1.5×10 -11 Hz/s.

TL;DR: In this paper, a search for gravitational-wave bursts in data from the three LIGO interferometric detectors during their third science run was reported. But no gravitational-warp signals were detected in the eight days of analysed data.
