Top Decay

  1. Jan 31, 2010 #1
    I am currently looking at a diagram of a top and anti top decay. The anti top decays into a weak boson and an anti bottom and the weak then decays into an electron and electron anti-neutrino. On the other side the top decays into a H+ particle and a bottom.

    What is this H+ particle, is it related to the Higgs Bosons and is it proven?

    H+ particle associates for me with a .. hydrogen ion - basically a proton..

    Thanks.
    And I meant a tauon anti-tauon.

    The charged Higgs boson, in supersymmetric extensions to the standard model and two-Higgs doublet models.

    Does that mean that the Higgs boson is proven?

    what do you mean "proven"?

    There is no connection between Feynman diagrams and what is seen in experiments... I can make up any model and thus Feynman diagrams I want... what makes you think that just because there is a certain Feynman diagram that must reflect the physical reality?

    tau decays to b,H? There are at least two things wrong with that, I think.

    one of the rules of Feynman diagrams is that it has to represent a possible process that can occur in nature.

    in one of my books, i have that t decays to a W which then decays into an anti muon and muon neutrino.
