Physicist
A physicist is a scientist who studies or practices physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales: from sub-atomic particles of which all ordinary matter is made to the behavior of the material Universe as a whole...

. He is one of the founders of the axiomatic approach to quantum field theory
Quantum field theory
Quantum field theory provides a theoretical framework for constructing quantum mechanical models of systems classically parametrized by an infinite number of dynamical degrees of freedom, that is, fields and many-body systems. It is the natural and quantitative language of particle physics and...

, and originated the set of Wightman axioms
Wightman axioms
In physics the Wightman axioms are an attempt at a mathematically rigorous formulation of quantum field theory. Arthur Wightman formulated the axioms in the early 1950s but they were first published only in 1964, after Haag-Ruelle scattering theory affirmed their significance.The axioms exist in...

 by Sellar and Yeatman. The PCT refers to the combined symmetry of a quantum field theory under P Parity, C charge and T time. Spin and statistics refers to the fact that in quantum field theory it can be proved that spin 1/2 particles obey Fermi-Dirac statistics whereas integer spin 0, 1, 2 particles obey Bose-Einstein statistics.
