Simple representation for the average value of the W -boson one-loop polarization tensor in a magnetic field B = const, calculated in the ground state of the tree-level spectrum, is derived. It corresponds to Demeur's formula for electron in QED. The energy of this state, describing ...

In a paper published today in theEuropean Physical Journal C, the ATLAS Collaboration reports the first high-precision measurement at the Large Hadron Collider (LHC) of the mass of the W boson. This is one of two elementary particles that mediate the weak interaction – one of the forces tha...

The W boson is one of the most intriguing particles described by the Standard Model. Together with the neutral Z boson, the charged W boson mediates the weak interaction, which causes beta decay and several other important processes in particle physics. The weak interaction has long intrigued sci...
Previous studies of the physics potential of LEP2 indicated that with the design luminosity of 500 inverse picobarn one may get a direct measurement of the mass of the W-boson with a precision in the range 30 - 50 MeV. This report presents an updated evaluation of the estimated error on ...

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 sample of 63 964 W -> e nu candidates and 51 128 W -> mu nu candidates, we measure m(W) = [80.413 +/- 0.034(...
A novel method of determining the mass of the W boson in the W+W- → lvl'v' channel is presented and applied to 667 pb-1 of data recorded at center-of-mass energies in the range 183-2 07 GeV with the OPAL detector at LEP. The measured energies of charged leptons and the results...
A new precision measurement of the W boson mass has been announced by the CDF collaboration, which strongly deviates from the Standard Model prediction. In this article, we study the implications of this measurement on the parameter space of the triplet extension (with hypercharge ) of the Standa...
