Homework Statement Considering 2 scattering particles with momenta ##p_{1}, p_{2}##, where ##p_{2} = 0## in the Lab reference. The momenta of these 2 particles after elastic collision are ##p_{1}', p_{2}'##, respectively. Due to the 4-momentum relation, we have ##p_{1i}p_{1}^{'i} = e_{1}e_{1}'...

Hi, Jedishrfu If I want to start to draw a diagram in this case (for Atlas, LHC), what should I draw at left hand side? Should I draw P + P \rightarrow ( because it is the collision of 2 protons) or W \rightarrow and Z \rightarrow ?

Hallo, Dear particle physicist, Despite I am major in biophysics, the particle physics looks attractive to me... So I just used Atlantis to check some experiments result from internet... Although I can find some resultant particles. I still cannot understand how to draw a Feynman diagram for...
