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…

Observation of tWZ production at the CMS experiment

CMS Collaboration

The first observation of single top quark production in association with a W and a Z boson in proton-proton collisions is reported. The analysis uses data at center-of-mass energie…

Combined effective field theory interpretation of Higgs boson, electroweak vector boson, top quark, and multi-jet measurements

CMS Collaboration

Constraints on Wilson coefficients (WCs) corresponding to dimension-six operators of the standard model effective field theory (SMEFT) are determined from a simultaneous fit to sev…

Search for -channel scalar and vector leptoquark exchange in the high-mass dimuon and dielectron spectra in proton-proton collisions at = 13 TeV

CMS Collaboration

A search for -channel exchange of leptoquarks (LQs) is performed in dimuon and dielectron spectra using proton-proton collision data collected at = 13 TeV with the CM…

High-precision measurement of the W boson mass with the CMS experiment

CMS Collaboration

In the standard model of particle physics, the masses of the W and Z bosons, the carriers of the weak interaction, are uniquely related. A precise determination of their masses is…

Search for heavy neutral Higgs bosons A and H in the Z channel in proton-proton collisions at 13 TeV

CMS Collaboration

A direct search for new heavy neutral Higgs bosons A and H in the Z channel is presented, targeting the process pp A ZH with H $\mathrm{t\bar{t…
