TL;DR: The performance of the jet trigger for the ATLAS detector at the LHC during the 2011 data taking period is described and was fully efficient for jets with transverse energy above 25 GeV for triggers seeded randomly at Level 1.

TL;DR: In this article, a measurement of the inelastic, non diffractive J/psi photoproduction cross section in the reaction e(+p --> e(+)J/psI X with the ZEUS detector at HERA was presented, the J/Psi was identified using both the mu(+)mu(-) and e (+)e(-) decay channels and events were selected within the range 4 1 GeV2, NLO calculations of the photon-gluon fusion process based on the colour-singlet model are in good agreement with the

TL;DR: In this article, the authors report branching fraction measurements for exclusive decays of charged and neutral B mesons into two-body final states containing a charmonium meson, using a sample of 22.72 +/- 0.36 million B anti-B events collected between October 1999 and October 2000 with the BABAR detector at the PEP-II storage rings at Stanford Linear Accelerator Center.

TL;DR: In this article, an analysis of exclusive charmless semileptonic B-meson decays based on 83x10{sup 6} BB pairs recorded with the BABAR detector at the {upsilon}(4S) resonance using isospin symmetry is presented.
