It's a matter of taste :) I'm not planning to work on cosmology (at least not in the near future). I want to fill in the gaps in my knowledge about cosmology and systematize what I gained through GR and QFT courses. I'm not sure if Weinberg's textbooks are appropriate for this purpose.
I know...
Could you recommend me some good textbooks on cosmology, please? I'm looking for something that covers both general relativity topics and, which is more important for me, particles astrophysics stuff. I like the structure of Bergström&Goobar's book but it's a little bit sketchy. Something with...

Homework EquationsThe Attempt at a Solution
I've started from writing out the amplitude. Here I know that fermion has definite helicity so I can't sum over spins but I should input explicit forms of spinors. Am I correct? How to do this?
I would be grateful for helping me...
OK, I can see that the hamiltonian is: H_{I}=g\phi\bar{\psi}\psi+h.c.
And I have to use it to fermion decay. Isn't this the simplest Yukawa theory? Does this hermitian conjugate make different?
Hi. Do you know any book/paper/lecture notes where I can find complete derivation of Feynman rules for both scalar and pseudo-scalar Yukawa theory, and maybe an example of application to decay of fermion?
