Wbosons mediate the weak interaction, one of the fundamental forces in physics. Because the Standard Model (SM) of particle physics places tight constraints on the mass of theWboson, measuring the mass puts the SM to the test. The Collider Detector at Fermilab (CDF) Collaboration now reports ...
Inspired by the astonishing 7 σ discrepancy between the recent CDF-II measurement and the standard model prediction on the mass of W-boson, we investigate the λ′ -corrections to the vertex of μ→νμ e ν e decay in the context of the R-parity violating ...
所以最重要的是要有模型无关(model-independent)的测量。比如LEP当年测Z的质量，是靠调整束流能量扫描得...

Two-loop large-mtelectroweak corrections toK→πνν¯for an arbitrary Higgs boson mass We consider for the first time the leading large top quark mass corrections, arising at higher order in electroweak interactions, to the rare decays K⃗... G Buchalla,AJ Buras - 《Physical Review D》...
But in 2023, researchers at CERN cast doubt on this discrepancy, after they reanalysed old data taken by the ATLAS detector at the LHC. They found a value for the W boson mass that once again agreed with the standard model prediction, dampening hopes for a deviation from known ...
Observing H→W(*)W(*)→e±μ∓pT in weak boson fusion with dual forward jet tagging at the CERN LHC Weak boson fusion promises to be a copious source of intermediate mass standard model Higgs bosons at the CERN LHC. The additional very energetic forward j... D Rainwater,D Zeppenfeld...
We conclude from this analysis that the total cross-section of single W-boson production depends significantly on the center-of-mass energy of the collider as well as on the anomalous parameters Δκγ and λγ. This means that the effective area of the collision increases for very high ...

The recent precision measurement of the W-boson mass reveals an exciting hint for the new physics as of the 3-3-1 model. We indicate that the 3-3-1 model c
