Griffiths is a graduate of The Putney School and was trained at Harvard University (B.A., 1964; M.A., 1966; Ph.D., 1970). His doctoral work, Covariant Approach to Massless Field Theory in the Radiation Gauge on theoretical particle physics, [4] was supervised by Sidney Coleman.
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 field equations of condensed matter physics are remarkably similar to those of high energy particle physics. As a result, much of the theory of particle physics applies to condensed matter physics as well; in particular, there are a selection of field excitations, called quasi-particles, that can be created and explored. These include:

Color charge is a property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics (QCD). Like electric charge, it determines how quarks and gluons interact through the strong force; however, rather than there being only positive and negative charges, there are three "charges", commonly called red, green, and blue.
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 .
Calculating the Minkowski norm squared of the four-momentum gives a Lorentz invariant quantity equal (up to factors of the speed of light c) to the square of the particle's proper mass: = = = + | | = where = is the metric tensor of special relativity with metric signature for definiteness chosen to be (–1, 1, 1, 1).
Canonical quantization then can be carried out for the shifted field φ(x,t) − v, and particle states with respect to the shifted vacuum are defined by quantizing the shifted field. This construction is utilized in the Higgs mechanism in the standard model of particle physics.
