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…

Observation of enhanced long-range elliptic anisotropies inside high-multiplicity jets in pp collisions at = 13 TeV

CMS Collaboration

A search for partonic collective effects inside jets produced in proton-proton collisions is performed via correlation measurements of charged constituents using the CMS detector a…

Measurement of energy correlators inside jets and determination of the strong coupling

CMS Collaboration

Energy correlators that describe energy-weighted distances between two or three particles in a jet are measured using an event sample of = 13 TeV proton-proton collision…
