    Cross Web
In summary, the conversation discusses the search for resources on the web that provide step-by-step calculus for calculating cross sections from Feynman diagrams for various processes in QFT. The speaker mentions their laziness and doubts on finding detailed information online, suggesting that professionals have other methods for obtaining this information. One book is suggested as a resource for understandable calculations.

Im currently studying different kinds of processes in QFT.
Does somebody know where to find all the calculus done step by step on the web.
It will be very helpfull.
thanks in advance,
Marco.

Just to be clear:

You want something on the web that shows all the math to calculate a cross section from a feynman diagram for many different processes (qed, weak, strong, etc)?

yep I am so lazy...

I doubt you will find much spelled out in nitty gritty detail on the web. Feynman diagram calculations are rather tedious to compute (hence the reason they're often given as homework problems). In practise, proffessionals use either a computer, have the result handy already, or they have learned the necessary tricks to get the information they want quickly, without doing the full algebra.

Probably the book that does the best job showing actual calculations in an understandable way is Griffiths 'introduction to elementary particles' as he does quite a few more examples than most books do (at least that I have read).

1. What are cross sections on the web?

Cross sections on the web refer to the representation of a three-dimensional object in a two-dimensional plane. This allows for easier visualization and analysis of the object's shapes and dimensions.

2. How are cross sections created on the web?

Cross sections are typically created using computer-aided design (CAD) software, which allows for precise and accurate capturing of the object's dimensions. This can also be done manually using measurements and calculations.

3. What is the purpose of using cross sections on the web?

Cross sections are commonly used in engineering, architecture, and other fields that involve designing and constructing physical objects. They allow for a better understanding of the object's structure and can help identify any potential issues or improvements.

4. Are there different types of cross sections on the web?

Yes, there are various types of cross sections that can be used depending on the object and its purpose. Some common types include orthogonal, oblique, and revolved cross sections.

5. How can cross sections on the web be shared and accessed?

Cross sections can be shared and accessed through various methods such as email, file sharing platforms, or by embedding them on a website. They can also be stored and accessed on a cloud-based platform for easy collaboration and accessibility.
