Dear all,

<div class="">There will be a CERN seminar on Thursday on the W boson mass measurements. Please forward as you wish. </div>
<div class=""><br class="">
</div>
<div class="">Most of you already know, but if not, this *might* be a signal of physics that is beyond the Standard Model of particle physics (BSM). Physics BSM has been vigorously sought and not found at LHC for more than a decade. </div>

<div class="">The mass of the W boson, a mediator of the weak force between elementary particles, is tightly constrained by the symmetries of the standard model of particle physics. The Higgs boson was the last missing component of the model. After observation
of the Higgs boson, a measurement of the W boson mass provides a stringent test of the model. We measure the W boson mass, MW, using data corresponding to 8.8 inverse femtobarns of integrated luminosity collected in proton-antiproton collisions at a 1.96 TeV
center-of-mass energy with the CDF II detector at the Fermilab Tevatron collider. A sample of approximately 4 million W boson candidates is used to obtain MW=80,433.5±6.4stat±6.9syst=80,433.5±9.4 MeV/c2, the precision of which exceeds that of all previous
measurements combined. This measurement is in significant tension with the standard model expectation.”</div>
