Journal ArticleDOI

Observation of an Anomalous Line Shape of the eta 'pi(+)pi(-) Mass Spectrum near the p(p)over-bar Mass Threshold in J/psi -> gamma eta 'pi(+)pi(-)

M. Ablikim, +433 more
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.
Journal ArticleDOI

Performance of the missing transverse momentum triggers for the ATLAS detector during Run-2 data taking

Georges Aad, +3015 more
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.
Journal ArticleDOI

Amplitude analysis of the chi(c1) -> eta pi(+)pi(-) decays

M. Ablikim, +432 more
- 13 Feb 2017 - 
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.
Journal ArticleDOI

Search for bottom-squark pair production with the ATLAS detector in final states containing Higgs bosons, b-jets and missing transverse momentum

Georges Aad, +3005 more
TL;DR: The results of a search for the pair production of the lightest supersymmetric partner of the bottom quark using 139 fb$−1}$ of proton-proton data collected at 13 TeV by the ATLAS detector is reported in this article.
Journal ArticleDOI

Search for a scalar partner of the top quark in the all-hadronic tt‾ plus missing transverse momentum final state at √s=13 TeV with the ATLAS detector

Georges Aad, +2949 more
TL;DR: A search for direct pair production of scalar partners of the top quark (top squarks or scalar third-generation up-type leptoquarks) in the all-hadronic t (t) over bar plus missing transverse momen was conducted in this paper.
