I Do additional Higgs fields also impart mass?

  1. Aug 22, 2017 #1
    in theories such as SUSY and MSSM where there are 5 Higgs fields,

    do the other higgs fields also impart mass?

    and how exactly is it determined which of the additional higgs fields impart mass on which particles?

    do the other higgs field impart mass on other higgs bosons?

    wouldn't there be indirect evidence of these additional higgs fields such as on branching ratios?

    In MSSM one Higgs field imparts mass to up-type quarks and the other to down-type.

    would this change branching ratio, since the higgs are different than in the SM with just 1 higgs?

    what about violating lepton universality?

    the branching ratio of what?

    in general the branching ratios of different decays are input to fits that are used to indirectly derive limits of those particle masses and coupling strengths.

    As for the LFV, it depends...

    this

    lead to testable predictions

    Well it's not an unknown conclusion.... the charged higgses for example have been tried to be used to describe the deviations from the SM predictions that the B-factories and LHCb have observed and lepton flavour violation (excesses of some flavour leptons to others). In particular they are used as additional Feynman Diagrams to consider... however these deviations are still not considered a discovery (or a SM failure) within the particle physics standards (not enough standard deviations)...

    I am not an expert in MSSM so I won't try to fuse/combine what I said together with what V50 did.

    Kodama, I made a mistake in replying. I promised myself not to respond to your threads, because I don't like your habit of misrepresenting the results of other people's experiments. Especially mine. But since I have entered the tar pit...there's nothing about the Higgs structure of the MSSM that breaks lepton universality.

    well think of all the other readers on this forum

    in the SM there is one higgs that couples and gives mass to both up-type quarks and the other to down-type, and the mass of this higgs is 126 gev.

    in MSSM, one higgs field, with mass 126 gev couples to up-type quarks and a different higgs field couples to down type.
    this different higgs presumably has a mass higher than 126 gev or else it would already be seen.

    since this higgs field differ, wouldn't it lead to observable differences up-type quarks and the other to down-type over the standard model higgs couple to both?

    False.

    This is the other reason I promised myself to stop replying to you. Your method of learning of posting incorrect things, hoping to be corrected is a) lazy, b) inefficient, c) annoying to everyone else since it can't as easily just be ignored.

    If you really cared about all the other readers on the forum, you would change your own behavior. You would ask questions more than write false statements, and you'd stop misrepresenting what other people have done.
