Web19 de ago. de 2015 · Insights Author 36,301 13,375 The fraction of particles that decays to some specific set of other particles. As an example, 57% of Higgs bosons decay to a pair of b-quarks (one quark and one antiquark). The branching ratio to b-quarks is 57%. This thread is from 2013. BBcode Guide Post reply WebIn typical situation the branching ratio is in the order around 10^−10 or smaller, probably beyond the ability of the Large Hadron Collider measurements to detect. However in some extreme case of parameters, especially large Yukawa couplings, the branching ratio could be as large as 10^−6 and the H± exchanging diagrams could become more important.
