B to tau nu和B to l nu(gamma)的实验状态

Experimental status of B to tau nu and B to l nu (gamma)

Roger Barlow

摘要:

给出了\babar \和Belle合作的实验结果,测量了衰变$B^\pm \to τ^\pm ν$的分支比,并对衰变$B^\pm \to e^\pm ν, B^\pm \to e^\pm νγ,B^\pm \to μ^\pm ν$和$B^\pm \to μ^\pm νγ$的分支比设定了极限

英文摘要:

The experimental results of the \babar\ and Belle collaborations are presented on the measurement of the branching ratio for the decay $B^\pm \to τ^\pm ν$, and the limits set on the branching ratios for the decays $B^\pm \to e^\pm ν, B^\pm \to e^\pm νγ,B^\pm \to μ^\pm ν$ and $B^\pm \to μ^\pm νγ$
