I plan to study particle physics especially about the quantum field theory but i don't know how to start with. I have studied mechanics,modern physics,electromagnetism using Serway Physics for Sciencetist and Engineers.I have also studied Waves and Vibrations using H.J Paind Book and also French book.I have studied Thermodynamics using Zemansky book. I have study calculus using Thomas Calculus and Stewart Calculus ,Complex analysis, linear algebra , vector calculus and Ordinary Differential Equations using Advance Engineering Mathematics by Kreyszig. So what is the next thing should i study? Please suggest some good books for me. Besides,do my current knowledge enough for studying theoretical classical mechanics.
