The 2010 Dirac Medal and Prize are awarded to Nicola Cabibbo (University 
La Sapienza, Rome, Italy) and Ennackal Chandy George Sudarshan 
(University of Texas, Austin, Texas, USA) in recognition of their 
fundamental contributions to the understanding of weak interactions and 
other aspects of theoretical physics.

 

Cabibbo's important contributions to theoretical physics include the 
recognition of the significance of mixing in weak interactions, which 
has established the existence of a new class of physical constants, 
whose first example is the Cabibbo angle. This angle determines the 
mixing of strange quarks with non-strange quarks and has been measured 
experimentally. With the discovery of a third family of quarks and 
leptons, quark mixing led to the understanding of the phenomenon of CP 
violation.

 

Sudarshan's important contributions to theoretical physics include the 
discovery (with Robert Marshak) of the V-A theory of weak interactions, 
which opened the way to the full description of the unified electroweak 
theory. He has also made innovative discoveries in the field of Quantum 
Optics, including the Optical Equivalence Theorem, which provides the 
foundation upon which the investigations of the manifestly quantum or 
non-classical character of the electromagnetic field are based.
