Measurement of the double Dalitz decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +689
The BESIII experiment measured the rare decay of the eta meson into two electron-positron pairs, determining its branching fraction to be about 2.6 × 10⁻⁵.
Updated measurement of the branching fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +703
Using a dataset of 7.33 fb of annihilation data collected with the BESIII detector at center-of-mass energies from 4.128 to 4.226 GeV, we report an updated measure…
Measurement of the branching fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +684
The branching fraction of the electromagnetic Dalitz decay is measured with an collision data sample collected by the BESIII experi…
Search for light pseudoscalar bosons, pair-produced in Higgs boson decays in the four-electron final state in proton-proton collisions at = 13 TeV
CMS Collaboration
A search for pairs of light neutral pseudoscalar bosons (A) resulting from the decay of a Higgs boson is performed. The search is conducted using LHC proton-proton collision data a…
First evidence for mixing-induced violation in B J/(1020) decays in pp collisions at 13 TeV
CMS Collaboration
A novel machine-learning-based flavor-tagging algorithm combining same-side and opposite-side tagging is used to obtain the equivalent of 27000 tagged B J/…
Search for light pseudoscalar boson pairs produced from Higgs boson decays using the 4 and 22 final states in proton-proton collisions at = 13 TeV
CMS Collaboration
A search for a pair of light pseudoscalar bosons (a) produced in the decay of the 125 GeV Higgs boson is presented. The analysis examines decay modes where one a decays int…
