Associated production mode of Higgs production at Tevatron
We know that at LHC the dominant mode of Higgs Production is Gluon Gluon Fusion, followed by Vector Boson Fusion, and then by Associated production.
Although Tevatron did not show any significance ...

Why do Higgs decays depend on the production method?
I'm reading about Higgs phenomenology and I have come across the following table.
I don't see why gluon fusion to $b \bar{b}$ is considered to be "impossible" in this table.
As far as I can tell, ...

Differential cross section $d\sigma/dp^{\gamma}_{T}$?
Why we care about $d\sigma/dp^{\gamma}_{T}$? What the physical meaning of it?
Why not plot $\sigma$ follow $p^{\gamma}_{T}$?. As in this picture.

Why does gg fusion dominate over q qbar annihilation at the LHC?
The cross section of top quark pair production is dominated at the LHC by gluon-gluon fusion, whereas at Tevatron, quark-antiquark annihilation is more prevalent. Why is this?
I know the fundamental ...

What are the main differences between $p p$ and $p \bar p$ colliders
I know that it is somehow related to the parton distribution functions, allowing specific reactions with gluons instead of quarks and anti-quarks, but I would really appreciate more detailed answers !

Particle colliders: why do they need an accelerator chain
Particle colliders like the LHC or the Tevatron use a complex accelerator chain to have particles at a given energy before being accelerated.
For example:
The CERN accelerator complex to inject in ...

Production of antiproton at the Tevatron
The Tevatron is a proton-antiproton collider; it collides a beam of protons against a beam of antiproton.
I can understand how we obtain the protons, but for the antiprotons? How are they produced?
