Search for sub-GeV dark particles in decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +685
Using (1008744)10 events collected with the BESIII detector at the BEPCII collider at the center-of-mass energy of , we report th…
First Measurement of the Absolute Branching Fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +691
We apply a tag-and-probe method to precisely measure the absolute branching fraction of the decay with the BESIII experiment at BEPCII. Starting with a large initia…
Measurement of the Higgs boson mass and width using the four-lepton final state in proton-proton collisions at = 13 TeV
CMS Collaboration
A measurement of the Higgs boson mass and width via its decay to two Z bosons is presented. Proton-proton collision data collected by the CMS experiment, corresponding to an integr…
Measurement of cross sections of from 4.682 to 4.951 GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +650
The process is studied by analyzing collision data samples collected at eight center-of-mass energies ranging from 4.682 to 4.951 GeV with…
