Notes for further insight; Also available in print N2 - While there are many good books in particle physics, very seldom if ever has a non-specialist comprehensive description of quantum field theory appeared. The intention of this short book is to offer a guided tour of that innermost topic of theor UR - https://ezproxy.mef.edu.tr/login?url=https://iopscience.iop.org/book/978-1-6432-7053-1 ER -
