For those of you who has taken QFT already (NOT those who wish to but not yet taken it) I have a question.
There are several textbooks on QFT and from my understanding the one by 'Mandl' is the shortest and easiest to follow, 'Zee' is fun to read, 'Peskin' is heavily calculation based, 'Weinberg' is beyond godlike.
So far I have taken quantum mechanics course using the book by 'Mandl' so I wonder if this will be enough preparation to take a course on QFT which uses the textbook by 'Mandl'? Or do I need further study in advanced Quantum mechanics using the book such as 'Sakurai'?
If any of you could advise me on this based on your experience in QFT, I would appreciate it.
