It should be `lefthanded' as is found experimentally. 3). 2. The rates for the pion decay reactions 7r- - e- + ve 7r- - - + vµ theoretically are in the ratio IF (7r- - e-ye) I' (7rµ-vµ) me z mµ as a result of the y'(1 - y5) coupling. 3 x 10-4 which agrees perfectly with the experimental ratio-and this despite the fact that phase space alone would have favoured the mode 7r- -p e- + ve! 3. e. of the relation between the weak and electromagnetic currents, is its prediction of `weak magnetism', the analogue for weak transitions of electromagnetic transitions due to the anomalous magnetic moments.

Note that the u and d quarks form an isospin doublet, and that s is an isosinglet. ) Spelled out in detail, the hadronic current reduces to just ha = urya(1 - 'Y5)(cos6cd+ sinOcs). 23) In the quark picture the weak interaction processes of hadrons are regarded as originating in the interaction of their constituent quarks. Thus neutron /3-decay is visualized as in Fig. 4 where the fundamental interaction is, at quark level, as in Fig. 23), and of the leptons. Later, when we come to discuss intermediate vector mesons or gauge bosons which mediate the weak interactions, the picture will be altered to that in Fig.

One may well wonder why longitudinal polarization states did not cause similar trouble in the case of virtual photons in QED. 13)] are innocuous. This suggests that it would be very interesting to extend gauge invariance to the present case of massive vector fields, perhaps resulting in a unification between weak and electromagnetic interactions. Note that we would then expect gw - e. 17) a very large mass! We shall see later that this estimate is close to what is suggested in the unified theory of weak and electromagnetic interactions.
