Higgs branching ratio
WebValidity of H->4f branching ratio approximation with PDG values We find that sometimes we calculate the Higgs signal cross section for pp->H->WW*/ZZ*->4f as σ (pp->H) * Br (H->VV) * Br (V->ff) * Br (V->ff) * (statistical factor) ...

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.

Because this branching ratio one can measure in the lab. But sometions people talk about decay into virtual particles, for example, the Higgs decay: H → Z + Z ∗ My knowledge tells me this is not a physical process since one Z-boson is off-shell. impacts on marine ecosystemsWebtwe have calculated the Higgs branching ratios for p, p+∆pand p−∆p, while all other parameters have been left at their central values. The error on each branching ratio has then been determined by ∆p +BR = max{BR(p+∆p),BR(p),BR(p−∆p)}−BR(p) ∆p −BR = BR(p) −min{BR(p+∆p),BR(p),BR(p−∆p)}. list top 25 countries by gdpWeb19 de ago. de 2015 · Insights Author 36,301 13,375 The fraction of particles that decays to some specific set of other particles.
