    Cosmology Cosmology textbooks covering general relativity and particle astrophysics

    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...

    Cosmology Cosmology textbooks covering general relativity and particle astrophysics

    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...

    How to apply explicit spinor forms for definite helicity fermions

    Homework Statement 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...

    Graduate Feynman rules for Yukawa theory

    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?

    Graduate Feynman rules for Yukawa theory

    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?
