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.
P = Probability that particle 1 has position r 1 in volume V 1 with spin s z1 and particle 2 ... List of equations in nuclear and particle physics; ... D.J. Griffiths ...
m is the particle mass, x represents distance measured in the direction of motion of the particle, Ψ is the Schrödinger wave function, V is the potential energy of the particle (measured relative to any convenient reference level), E is the energy of the particle that is associated with motion in the x-axis (measured relative to V),
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 .

The calculation of probability amplitudes in theoretical particle physics requires the use of large, complicated integrals over a large number of variables. Feynman diagrams instead represent these integrals graphically. Feynman diagrams give a simple visualization of what would otherwise be an arcane and abstract formula.
Standard Model of Particle Physics. The diagram shows the elementary particles of the Standard Model (the Higgs boson, the three generations of quarks and leptons, and the gauge bosons), including their names, masses, spins, charges, chiralities, and interactions with the strong, weak and electromagnetic forces.
