Decay of heavy mesons into possible spin 3/2 leptons
Description
The recent interest in the study of possible spin 3/2 leptons motivated this calculation of the decay rate of heavy mesons into these leptons. The mesons may be UPSILON particles (bb sup(-) systems) or any other system of the qq sup(-) (quark-antiquark) kind with mass larger than those of the upsilon particles, for example, tt sup(-) bound states (not yet detected). The decay rate of these mesons is calculated as a function of the mass of the spin 3/2 leptons. The results obtained are compared with those of the spin 1/2 leptons. (Author)
Abstract (Portuguese)
Devido ao recente interesse no estudo de possiveis leptons de spin 3/2, calcula-se a taxa de decaimento, nestes leptons, de mesons pesados tais como: particula UPSILON (sistema bb sup(-)) ou qualquer outro sistema do tipo qq sup(-) (quark-antiquark) de massa maior do que as das particulas UPSILON, como por exemplo, estados ligados tt sup(-) (ainda nao detetados). Fazemos uma estimativa da taxa de decaimento desses mesons em funcao das massas dos leptons de spin 3/2. Confrontam-se esses resultados com os obtidos para os leptons de spin 1/2.
