After an unexpected measurement by the Collider Detector at Fermilab (CDF) experiment in 2022, physicists on the Compact Muon ...

This time, physicists, including core UCLA researchers, have accurately measured the mass of the W boson — more precisely ...

The CMS experiment at CERN is the latest to weigh in on the mass of the W boson—an elementary particle that, along with the Z ...

A long-awaited calculation of the W boson’s mass agrees with theory, contradicting a previous anomaly that had raised the ...

The W boson, predicted in the 1960s and discovered at CERN in 1983, is one of these cosmic masterminds. And without it, the ...

Compact Muon Solenoid Experiment at Large Hadron Collider, CERNW boson candidate event with a reconstructed muon (red line) ...

CERN’s calculation of the W boson’s mass agrees with theory, contradicting a previous anomaly that had raised the possibility ...

He was presenting new data on the mass of the W boson, a fundamental particle that is crucial for processes like nuclear decay and setting the mass of the Higgs boson. Questions about the W boson ...

Geared for discovery more so than delicacy, the LHC is defying expectations by rivalling lepton colliders for precision.

This new measurement, which is a first for the CMS experiment, uses a new technique that makes it the most elaborate investigation of the W boson's mass to date. Following nearly a decade of ...
