Semileptonic transition of B in noncommutative space- time
In this paper, we study the noncommutative effect on the semileptonic transition of B Ò Dlv . We replace the weak interaction vertex in the ordinary space with its counterpart in the noncommutative space. It is shown that, more new form factors are needded to describe the hadronic part of the transi...

| description | In this paper, we study the noncommutative effect on the semileptonic transition of B Ò Dlv . We replace the weak interaction vertex in the ordinary space with its counterpart in the noncommutative space. It is shown that, more new form factors are needded to describe the hadronic part of the transition amplitude. All the form factors are obtained at the lowest order of three point QCD sum rule. Consequently, the decay rate of B Ò Dlv is calculated and a bound of the order of 4 GeV on is given for B Ò Dlv=(5.5 ± 0.5) × 10-2. |
