We present a singly charged scalar extension of the scotogenic model, the scotogenic-Zee model, which resolves the recently reported deviations in the W boson mass as well as lepton g - 2. The model admits a scalar or a fermionic dark matter while realizing naturally small radiative neutrino...
“That’s one of the things that’s been driving us: if you know the Z boson mass precisely, that allows you to calculate the W boson mass precisely, because it’s the connection that the theory tells you.” The Higgs boson mass allowed physicists to infer that the mass of the W ...
A measurement of the W boson mass is presented using data taken by the ALEPH detector during the 1997 running of the Large Electron-Positron Collider II (LEPII) at the European Center for Particle Physics (CERN) near Geneva, Switzerland. A high efficiency, high purity analysis which selects ...
W-boson mass determination from the threshold behavior of σtot(e +e -→W +W -) 来自 Semantic Scholar 喜欢 0 阅读量: 23 作者: Z Hioki 摘要: The total cross-section of e +e −→W +W − has been studied in relation to the W-boson mass determination in the framework of ...

The W-boson mass has been measured using the ALEPH detector at LEP. Preliminary results from data taken in 1998 are added to previous measurements to give <SPAN style="FONT-STYLE: italic">m</SPAN><SUB><SPAN style="FONT-STYLE: italic">W</SPAN></SUB> = 80.411 ± 0.064(stat.) ± 0.0...
We report a measurement of the W boson mass based on an integrated luminosityof 82 pb$^{-1}$ from \ppbar collisions at $\sqrt{s}=1.8$ TeV recorded in1994--1995 by the \Dzero detector at the Fermilab Tevatron. We identify Wbosons by their decays to $eu$ and extract the mass by...
First run II measurement of the W boson mass at the Fermilab Tevatron We describe a measurement of the W boson mass m(W) using 200 pb(-1) of root s=1.96 TeV p (p) over bar collision data taken with the CDF II detector. With a... T Aaltonen,A Abulencia,J Adelman,... - 《...
This letter describes the first observation of W boson pair production at a centre-of-mass energy ja:math in the OPAL detector at LEP. The analysis is sensitive to all expected W + W decay channels. A total of 28 events have been selected for an integrated luminosity of 9.89±0.06 pb 1...
