B physics

Turning now to the b sector, much less data exist here (compare Table 13.1 and 13.2) and the situation is to some extent simpler since the naive 

Before the above value was established, at the 25th International Conference on High Energy Physics, Gittelman, (1991) presented the results 

Semi-leptonic and exclusive R decay channels have been observed (BR (R — e 1/ hadrons) 10.7 0.5% and BR(R n + u+ hadrons 10.3 0.5%)] but it is fair to say that R physics has barely begun and offers great potential for an extremely rich experimental programme both at electron and hadron machines. The most crucial question that we expect to be answered from R physics concerns CP violating asymmetries. This subject will be discussed in Chapter 19. 

Bs mesons have not yet been sufficiently firmly established to be given an entry in the main listing of the Particle Data Group. Recently, however, CUSB II (1990) has reported evidence from the study of the photon signal in R — R 7 and R — Rs 7 that a significant number of Bs mesons are produced in T(55) decays and that the hyperfine splitting M(R ) - M Bs) 47 MeV/c2 is compatible with M(R ) - M(R) 45 MeV/c. Both, in turn are not incompatible with the empirical rule on the universality of 0.54 - 0.58(GeV/c)2. 

perhaps, worth illustrating some details of R physics using the decay R — D P as an example. This reaction can be monitored if the
