SUMMARY

The discussion centers on the phenomenological model for elastic scattering of positive pions by protons at energies between 200-1200 MeV. Participants highlight the complexity of the problem, noting the necessity of understanding electromagnetic and strong interactions, as well as the use of distorted wave Born approximation algorithms. Key aspects include the consideration of polarization observables and the complications arising from low-energy interactions involving composite particles. Participants recommend consulting specialists or academic resources for deeper insights.

PREREQUISITES
  • Understanding of nuclear physics principles, particularly elastic scattering.
  • Familiarity with composite particles, specifically pions and protons.
  • Knowledge of electromagnetic and strong interactions in particle physics.
  • Experience with distorted wave Born approximation algorithms.
NEXT STEPS
  • Research the application of distorted wave Born approximation in nuclear physics.
  • Study polarization observables in particle interactions.
  • Explore the role of form factors in elastic scattering processes.
  • Consult academic papers on elastic scattering of pions by protons, particularly from resources like arXiv.
USEFUL FOR

Physicists, nuclear researchers, and students specializing in particle physics, particularly those focusing on scattering processes and strong interactions.

Dear friends,

Can you help me to understand the phenomenological model?

Best regards

Phenomenological model of what? What don't you understand about it?
 
Your question is too vague. You need to specify what phenomenom you are concerned with.
 
Sorry freinds,

my question about Phenomenological model for elastic scattering of positive pions by proton in energy 200-1200Mev.

Best regards.
 
Well at least he was specific.

This is a tough and messy highly specialist oriented nuclear physics problem that I am not in the position to help you with really. But I do know a little bit of the game they play b/c the particular interaction is known to be fruitful in principle for experimental data on the strong interaction (dont ask me for specifics).

The pion and protons fundamentally are composite particle, and there will be electromagnetic interactions as well as strong interactions taking place. Typically the game is to guess appropriate form factors, and run distorted wave born approximation algorithms on them etc.

Anyway, youu have a spin 0 and spin 1/2 target so you will have several polarization observables (from the flip and antispin flip amplitudes)+ unpolarized ones. You are also working with low energies so there is going to be residual complications on the compositness of the target (say a heavy nucleus with a lot of protons floating around on the outer orbitals).

You will need to consult a specialist for more details, say at your local university.. I very much doubt that by chance someone here knows the details explicitly.
 
Dear Haelfix,
thank you for your reply and explanation BUT if you have some research for elastic scattering of pions by proton send me these papers...
