CMS Experiment at CERN Measures W Boson Mass with Unprecedented Precision
"The new result, achieved by analyzing data from proton collisions at the LHC, is the most precise measurement of the W boson mass ever made."
The CMS experiment at CERN has just announced its first measurement of the mass of the W boson, a fundamental particle that plays a key role in the weak force and nuclear fusion. This new result, achieved by analyzing data from proton collisions at the Large Hadron Collider (LHC), is the most precise measurement of the W boson mass ever made at the LHC and is consistent with the predictions of the Standard Model of particle physics.
This precise measurement helps test the Standard Model and could hint at new physics if discrepancies arise. CMS's result aligns with previous measurements except for one from the CDF experiment at Fermilab, which suggested a significantly higher mass in 2022, sparking further studies in the field.
LIP has been a member of the CMS collaboration since its inception, contributing significantly to the design and construction of key components of the detector. LIP also played a key role in discoveries like the Higgs boson and continues to contribute to physics research at the LHC, particularly in areas like Higgs physics, B physics, and the search for new particles.
The CMS experiment and LIP's ongoing efforts help push the boundaries of particle physics, with future upgrades to the LHC promising even more precise measurements.
