The aim is to provide a description of the theoretical work, as well as a synthesis of the experimental effort, which makes interesting reading for both theorists and experimentalists. In particular, the experimental measurements, discussed in the second part of the book, are systematically related to the theoretical 606 $aZ bosons 606 $aW bosons 606 $aWeak interactions (Nuclear physics) 608 $aElectronic books. 615 0$aZ bosons. 615 0$aW bosons. 615 0$aWeak interactions (Nuclear physics) 676 $a539.7 676 $a539.721 700 $aTenchini$b Roberto$0475160 701 $aVerzegnassi$b Claudio$048941 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910458659503321 996 $aPhysics of the Z and W bosons$91441555 997 $aUNINA
