This book presents more than 200 problems, with detailed guided
solutions, spanning key areas of particle physics and astrophysics. The
selected examples enable students to gain a deeper understanding of
these fields and also offer valuable support in the preparation for
written examinations. The book is an ideal companion to Introduction to
Particle and Astroparticle Physics: Multimessenger Astronomy and its
Particle Physics Foundations, written by Alessandro De Angelis and Mário
Pimenta and published in its second edition in Springer's Undergraduate
Lecture Notes in Physics series in 2018. It can, however, also be used
independently. The present book is organized into 11 chapters that match
exactly those in the companion textbook, and each of the exercises is
given a title to facilitate identification of the subject within that
book. Some new exercises have been added because they are considered
helpful on the basis of the experience gained by teachers while using
the textbook. Beyond students on relevant courses, exercises and
solutions in particle and astroparticle physics are of value for physics
teachers and to all who seek aid to self-training.
