Higgs decay loop function

  1. Apr 12, 2013 #1
    Hi all,

    Has any one know how to calculate the loop function of Higgs decay to photons/ gluons by t quark , or a useful reference.

    Isn't it exactly the same as for the production?

    Replace the gluons by photons.

    Yes, I mean the loop function of the decay or production ..

    Google this.
    Higgs production through gluon fusion at leading order - Nikhef
    That is one that I had looked at before. Alternatively you could always look at the code for production or decay in one of the generators if you get stuck.

    Hope it helps
