Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation. The field also studies combinations of elementary particles up to the scale of protons and neutrons , while the study of combination of protons and neutrons is called nuclear physics .
For example, when rotating a stationary (zero momentum) spin-5 particle about its center, is a rotation in 3D space (an element of ()), while () is an operator whose domain and range are each the space of possible quantum states of this particle, in this example the projective space associated with an 11-dimensional complex Hilbert space .
Further lecture courses in the Theoretical Minimum series have been delivered by Susskind, on these subjects (or with these titles): Advanced quantum mechanics. Higgs boson. Quantum entanglement. Relativity. Particle Physics 1: Basic Concepts. Particle Physics 2: Standard Model. Particle Physics 3: Super-symmetry and Grand Unification. String ...
Introduction to Elementary Particles, by David Griffiths, is an introductory textbook that describes an accessible "coherent and unified theoretical structure" of particle physics, appropriate for advanced undergraduate physics students. [1] It was originally published in 1987, and the second revised and enlarged edition was published 2008.
The Theoretical Advanced Study Institute or TASI is a four-week summer school in high-energy physics or astrophysics held yearly at the University of Colorado at Boulder.The school is meant primarily for advanced graduate students and consists of a series of pedagogical lectures on selected topics given by active researchers in the field.
The Standard Model of particle physics is the theory describing three of the four known fundamental forces (electromagnetic, weak and strong interactions – excluding gravity) in the universe and classifying all known elementary particles.

The method convenient also in the case of many-body physics, like in description of atomic, nuclear or molecular collisions is the method of R-matrix of Wigner and Eisenbud. Another class of methods is based on separable expansion of the potential or Green's operator like the method of continued fractions of Horáček and Sasakawa.
