I found this presentation (http://v17flavour.in2p3.fr/MondayMorning/Jager.pdf) which uses 4 for C9 and -4 for C10 at 4.6 GeV on page 8, which is about the region I'm interested in. It's very vague though, so I think just a more precise version of this figure is exactly what I'm looking for
So essentially the issue is that loop diagrams are too computationally expensive for me to compute, which is why I'm using effective field theory to stand in for the b > s l l vertex at low enough energy while calculating everything at 1st order. Is this a reasonable thing to do?
And is there...
So this decay should only be able to happen via the penguin feynman diagram right, but isn't the point of the effective field theory to replace the loop diagrams with a single vertex, which can be represented using a wilson coefficient?
Surely this coefficient has a specific value at the ~10s of...
Hi, does anyone happen to know a paper somewhere with a list of the standard model wilson coefficients for effective field theory?
I see the same basis everywhere and I can find the new physics corrections, but nowhere seems to have an actual number for the standard model value? Specifically...
