In summary: Fstart=0&%2Fend=0&%2Fabstracts=show&%2Forder=-announced_date_first&%2Fsize=50In summary, the conversation was about understanding the phenomenological model of elastic scattering of positive pions by protons at energies between 200-1200 Mev. The speaker requested help in understanding the concept and asked for any relevant research papers. The respondent explained that this is a highly specialized topic in nuclear physics and suggested consulting a specialist at a local university for more information. The respondent also mentioned the complexity of the topic, involving electromagnetic and strong interactions and the use of form factors and algorithms. The speaker requested any available research papers on the topic.

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...
 

1. What is a phenomenological model?

A phenomenological model is a scientific model that attempts to explain and understand a specific phenomenon by observing and analyzing its characteristics and behaviors. It is based on empirical data and observations rather than theoretical assumptions.

2. How is a phenomenological model different from other scientific models?

Unlike other scientific models that are based on theoretical frameworks and mathematical equations, a phenomenological model focuses on understanding the essence of a phenomenon through observation and description. It does not aim to predict or explain the underlying mechanisms of the phenomenon.

3. How can friends help in understanding a phenomenological model?

Friends can provide valuable insights and perspectives in understanding a phenomenological model by sharing their own observations and experiences related to the phenomenon. They can also offer support and guidance in interpreting the data and refining the model.

4. What are the benefits of using a phenomenological model?

One of the main benefits of using a phenomenological model is that it allows for a deeper and more holistic understanding of a phenomenon, as it takes into account the subjective experiences and perspectives of individuals. It also provides a more flexible and adaptable approach compared to other scientific models.

5. Are there any limitations to a phenomenological model?

Yes, there are some limitations to a phenomenological model. Since it is based on subjective experiences and interpretations, it may be difficult to generalize the findings to a larger population. It also requires a significant amount of time and effort to collect and analyze the data, making it a less practical option for certain research projects.
