Ok, for me "fluent" just meant that I could hold a conversation without stopping to find my words. So, my bad, I remove that. Do you think that replacing "required" by "encouraged" or "given the opportunity" would be better? Because I think it is important to keep the fact that the internship...

Thank you for removing the files, i don't think there's much of interest to learn here but still i'll do a new version without informations ! I won't have any experimental/theoretical experience by then, this internship is supposed to be our first real contact with the research domain. About...

Thank you very much, I made the changes you suggested ! In fact I am not applying to a school but directly to the research department. I have found a page with a "contact the research expert" form, but I also found the email of the responsible of the department, so I don't really know what...

Mentor note: removed the attachments, see post 3 Hi everyone, I am not sure if this is the right place to ask this, if I am wrong I will delete this thread as soon as possible. I am a french student, currently looking for a 6-months internship abroad, required by my school. Being interested in...

Thank you very much, this really made it much clearer !

Ok i get that ! One last question: when asked to compute "the amplitude for a \phi->\phi \phi decay" without further precision, how do we fix the external points? Do we have to integrate over all possible momenta configurations?

Well I'm not really sure that helps me... When you say "allowed diagrams with the correct in and out states", you mean all diagrams with a given number of vertex that link the external points ( for example \phi_{pi} )? Edit : in fact i understood what bothered me with the derivative.

it's mostly the second problem, i really don't understand how to link a physical situation to the diagrams. I also have a problem with the momentum factors due to particles entering/leaving a vertex (but i think this might become more understandable if i understand how to get the diagrams)

Hi everyone, not much to be said about me, I'm a french graduate student in fundamental physics, mostly here to find help in my attempt of understanding quantum fiel theory through Scwhartz's "Quantum field theory and the standard model"

Hi everyone, sorry if this is not the right place to post that question but I'm new to this forum, i'll delete if necessary. I am currently trying to learn QFT from Matthew Schwartz's "Quantum field theory and the standard model", quite clear during the first chapters, but i have been...
