(A Primer for a Basic Education)

The content of this manuscript is the rst semester course in quantum eld
theory that I have delivered at the Physics Department of the Faculty of
Sciences of the University of Bologna since the academic year 2007/2008.
It is a pleasure for me to warmly thank all the students and in particular
Dr. Pietro Longhi and Dr. Fabrizio Sgrignuoli for their unvaluable help
in nding mistakes and misprints. In addition it is mandatory to me to
express my gratitude to Dr. Paola Giacconi for her concrete help in reading
my notes and her continuous encouragement. To all of them I express my
deepest thankfullness
