For posterities,
a good summary of B physics, that explains ideas, without a lot of calculations is this:

With it you can check if you have understood, without reading 3 or 4 books.
I do an error in my previous post, now you can understand that I say the same thing, it's unlikely that s-quarks will be produced to LHC.
I don't understand what do you mean with "theoretical evidence" .
The experiments say that standard model works fine, like for...
I have read these:

I'm searching to understand a more detailed modeling of QCD interactions. For example in exchange diagram, Rosner says that you have to consider 3 or more gluon for...
This is a color-favored Feynman diagram.
I think I need to do the Clebsch–Gordan of SU(3) for initial and final state to understand this, because they are in a given representation to be bound states. I'm not sure of this.
Thank you for the reply.
I report you what I understand of fine-tuning.
My english is not much good, so forgive me.
When you build a new theory, you have a lot of free parameters, in Standard Model they are for example the masses of quarks, Cabibbo's angle, ecc
You have to set values for parameters that can reproduce...
Can someone explain to me what is a Feyman diagram color-suppressed at the tree-level?
It's my first post, sorry if I'm too needy, I will try to improve.
Thank you for the answers.
