That probably depends on your prerequisite knowledge. Have you taken quantum mechanics yet? Quantum field theory?
I do not see how it depends in the prerrequisites. Oh wait, of course, if he has learnt QFT, then the easiest way to learn QFT is to sit down and remember that you already know it. What about asking what curriculum should a career have if the main goal is only to best the Standard Model.
you're are absolutely right i get "Symmetry and the Standard Model" by Matthew Robinson so ? any comment
Terrific book for newcomers! I predict that will be one of the most popular introduction books to QFT and the Standard Model in the years to come. Also, they often refer to Srednicki's book which is one of the standard texts in QFT nowadays. So you can continue your studies with Srednicki's book after you have finished Robinson. Srednicki is a bit weak in given conceptual insights, something were Robinson is excellent with. So both books complement each other perfectly. Note, there are QFT books and particle physics books, both aim at explaining high energy physics. Particle physic books skip a lot of the nitty gritty theoritical details and will get you faster to the Standard Model.
Because that would be an entirely different question. If prerequisites aren't relevant, then what would you say to a third grader interested in learning string theory? You'd recommend they pick up Zwiebach? It's hard to tell from your vague sarcasm whether you are implying that QFT and the SM are one in the same: they aren't. See Griffiths for a way to teach the symmetries and interactions of the SM without a mention of the word "field." And talk to anybody who does condensed matter theory if they know what a quantum field is, and then ask them if they know what the SU(3)xSU(2)xU(1) Standard Model is. My guess is that the answers to these questions will not be the same.
