Direct constraint on the Higgs–charm coupling from a search for Higgs boson decays into charm quarks with the ATLAS detector

Georges Aad, +2797 more
TL;DR: In this article , a search for the Higgs boson decaying into a pair of charm quarks is presented, which yields an observed (expected) upper limit of $26$ ($31$) times the predicted Standard Model cross-section times branching fraction for a Higgs particle with a mass of 125 GeV.

Measurement of the form factors in the decay $D^+ \to \omega e^+ \nu_{e}$ and search for the decay $D^+ \to \phi e^+ \nu_{e}$

M. Ablikim, +400 more

TL;DR: In this article, an improved measurement of the branching fraction was presented, where the parameters defining the corresponding hadronic form factor ratios at zero momentum transfer were determined for the first time, and they measured them to be $r_V = 1.24\pm0.09\pm 0.06$ and $r-2 = 1

TL;DR: In this paper , the authors performed searches for nonresonant and resonant di-Higgs boson production in the bb¯γγ final state and obtained expected upper bounds on the cross-sections of diHiggs Boson production.
Journal ArticleDOI

Observation ofJ/ψ→γηπ0

M. Ablikim, +428 more
- 14 Oct 2016 - 
TL;DR: In this article, the first study of the branching fraction for the BESIII detector at the BEPCII facility was presented, where the authors used a Bayesian approach to determine the upper bound of the probability that the branching fractions are 2.5 and 6.6 at the 95% confidence level.
Journal ArticleDOI

Measurement of the integrated luminosity and the center-of-mass energy of the data taken by BESIII at $\sqrt{s} = 2.125$ GeV

M. Ablikim, +323 more
- 26 May 2017 - 
TL;DR: In this article, a dedicated data set of collision data was collected at the center-of-mass energy of 2125 GeV with the BESIII detector at the BEPCII collider by analyzing large-angle Bhabha scattering events.
