Jet events and Deeep Inelastic Scattering (Scaling Behavior) at the same time?
I am a philosopher of physics, so I already apologize for potential ignorance. I have also graduated in physics, but I now analyze problems on another level and also forgot some of the mathematical ...

Identifying quark constituents of the proton using proton-electron scattering
Rutherford's scattering experiment of the atom is qualitatively convincing just by the detection of near 180 degree deflection of positively charged alpha particles when shot through the dense lattice ...

Do electrons scatter off of the up quarks inside protons and neutrons?
Since they are different types of fermions, and of opposite charge, and the up quark has only 2/3 of a 'full' charge; is its trajectory changed as much by scattering off of a same-charge down quark?
...

Help to derive the inequality bounds $1/4\leq F_2^{\rm en}/F_2^{\rm ep}\leq 4$ (Halzen & Martin's exercise 9.7)
The structure functions $F_2^{\rm ep}$ and $F_2^{\rm en}$ for electron-proton and electron-neutron deep inelastic scattering deduced from the model of valence quarks and sea quarks of proton and ...

Scattering $u\bar{d} - c\bar{b}$
I'm trying to define if the scattering $u\bar{d} \rightarrow c\bar{b}$ is possible in any of the fundamental interactions, I know that in QCD (channel t) is allowed because of the charge conservation, ...

How are the structure functions in Deep inelastic scattering measured?
I've been reading lots of different textbooks on the parton model and deep inelastic scattering and the discovery of quarks, and most of the time whenever I see a plot, it's about the measurement of ...

Why is it that the Callan-Gross relation predicts that quark has spin 1/2?
I'm studying deep inelastic scattering, and currently at the part where they say the Callan-Gross relation:
$$F_1 (x) = \frac{1}{2x} F_x (x)$$
where $F_1$ and $F_2$ are the dimensionless structure ...

Deep inelastic scattering
Quarks can not observed directly in isolation so that they only can exist in the form of colorless hadron.
So we may suggest some questions like "Is quark actually exist?", "Is it just mathematical ...

In inelastic scattering does the exchange photon interact with sea quarks?
In deep inelastic scattering between electon and proton, the electron emits a photon that interacts with a quark of the proton, which absorbs it. Then, in a second time, the quark interacts with the ...

Evidence for standard model description of neutrons
as I don't know too much about experiments I have the following question concerning the evidence about the quark constituents in neutrons.
After a quick google investigation I found some sentences ...

Quark Radius Upper Bound
If quarks had internal structure (contradicting current beliefs), what is the lowest
upper bound on their "radius" based on current experimental results?
If possible, I'd prefer to only consider ...

$WW\to t\bar{t}$ growth
I was told recently that "it is well known that processes like $WW\to t\bar{t}$ ($t$ being a top, or any massive fermion) grows linearly with the energy in the absence of an Higgs boson." Does anyone ...
