Some Important Contributions:
First paper to discuss how
the strong, weak, and electromagnetic coupling constant
can merge to a single coupling constant in a grand
unified theory, with Howard Georgi and Steven Weinberg.
Suggested a possible near symmetry of the universe
(now known as Peccei- Quinn symmetry) to explain
how strong interactions can maintain the symmetry
between particles and antiparticles (CP symmetry)
when weak interactions do not, with Roberto Peccei.
Showed how physics of quarks can be used to predict
some properties of the physics of hadrons (which are
particles made from quarks),with Enrico Poggio and Steven Weinberg.
This is now known as quark-hadron
Phenomenological analyses of CP violation in B meson decays in the
standard model with the Kobayashi-Maskawa mass matrix.
