Can we deduce if a filed force is atractive in some situation from the differential cross-section?
When a beam of particles is directed against a target, the particles in the beam become scattered in different directions. The differential cross-section tries to describe this scattering:
$$\frac{\...

Conceptual meaning of differential cross section with respect to theta
By doing a seminar paper about Compton scattering I came across two different differential cross-sections:
$\frac{d\sigma}{d\Omega}$ and $\frac{d\sigma}{d\theta}$ where $\theta$ is the scattering ...

$2 \to 2$ scattering cross section in arbitrary theory
What is the general method to compute the $2 \to 2$ scattering cross section given an arbitrary Lagrangian ? I would like a step by step recipe that can be easily implemented in Mathematica.
For ...

How is strong coupling constant related to cross section?
I've been looking through different Pdfs /articles on strong coupling constant and nearly all of them involve cross section, I've understood what cross section is but not how is it connected to ...

How to determine the sign of coupling constant in quantum field theory?
Experimentally, we determine the value of the coupling constant by measuring the scattering cross-section and compare it with the results calculated by the scattering amplitude.
However, in the ...

Difference between cross section and probability of interaction
When I read some textbooks I find that the definition of cross section is the
probability. Of incident neutron interact with a matter .but I find many other (cross section of fission, scattering, ...

For which values of $n$ and $n'$ are $n \to n'$ particle scattering cross-sections well-defined?
When studying particle interaction events in QFT, we usually consider either (a) $2 \to 2$ particle "scattering" events, whose probabilities are quantified by scattering cross-sections, or (b) $1 \to ...

From a cross section to a probability
This is homework problem:
Given the cross-section of a neutrino-electron scattering, what is the probability for a solar neutrino to scatter with a electron as it goes through the center of the Earth?

Do molecular bounded systems shield or reduce neutron cross-sections?
When talking about neutron cross-sections, literature is usually investigating isolated cases of Neutron + Atom. Here, the abundance of hydrogen is dominating neutron fluxes through material.
