This is odd. I checked the masses and they were okay. I now checked them again, and they are not okay. I must have used the wrong mass...

This is problem 2.7 from Griffiths' Introduction to Elementary Particles. Here are the two reactions that I am trying to examine: (c)...

Yes, that is mine. I just cannot find anything resembling that one among Griffiths' diagrams. Or could it perhaps be this one:

This is problem 2.3 in Griffiths' Introducion to Elementary Particles. I have Griffiths' solutions, otherwise I would be completely...

Thank you. I find it always interesting to read recommendations and comments on books. I noticed that Susan Rigetti has chosen the exact...

The particular derivation I gave requires knowledge of complex analysis and is quite lengthy. I therefore thought that it illustrated...

Thanks a lot. This is a derivation that I can follow. For physics purposes it is of course much easier to look up the zeta function and...

That's why I decided to use an online calculator. I just thought that there might be a simple, straightforward way to solve this. Your...

I am also going back through Griffiths Quantum (3rd edition) after years off...........you should not get bogged down in the entire...

Thank you for your detailed answer. It is, however, somewhat over my head. When I asked the question I had no idea that this was such a...

I obviously don't need it in this case. I will need it for similar questions that may come up in the future.

This is related to the Basel Problem. Starting from there, you can separate the odd and even terms, then note that the even terms are...

So apparently there is no straight forward algorithm for this. I will look for an online calculator then.

I have been working through problem 2.7 in Griffiths' QM book. Everything is pretty much clear, except that at the very end the...

This is very helpful, thanks a lot.
