Searching for signatures of new physics in B→Kνν¯ to distinguish between Dirac and Majorana neutrinos
We conduct a model-independent analysis of the distinct signatures of various generic new physics possibilities in the decay B → K ν ν ¯ by analyzing the branching ratio as well as the missing mass-square distribution. Considering the final neutrinos to be of the same flavor with non-zero mass, we d...
