The CDF-II collaboration's recent high-precision measurement of W-boson mass indicates new physics contribution(s) beyond the Standard Model. We investigate the possibility of the well-known canonical Scotogenic model to explain the CDF-II measurement. The Scotogenic model is a popular scenario ...

In the present letter, a Dirac neutrino mass model is presented in the view of the new result on W boson mass ofmWCDFII=80.4335±0.0094GeV, recently reported by the CDF-II experimental collaboration. The newly measured value of the W mass anomaly shows a 7-σdeviation from that predicted ...

In this thesis measurements of the inclusive $W$ and $Z/\\gamma^*$ boson production cross-sections in proton-proton collisions at a centre-of-mass energy of $7$ TeV are presented. The measurements are performed using the decays of $W ightarrow eu$ and $Z/\\gamma^* ightarrow ee$. ...
We reevaluate the hadronic contributions to the muon magnetic anomaly, and to the running of the electromagnetic coupling constant at the -boson mass. We include new cross-section data from KLOE, all available multi-hadron data from BABA... M Davier,A Hoecker,B Malaescu,... - 《European ...
