There he started to study parity violation in the decay of hyperon particles.

The lack of left-right symmetry is known as parity violation.

At that time, the experimental result gave only an indication of a 2 standard deviation effect of possible parity violation.

This changed with the discovery of parity violations in particle physics.

A major mystery that has focused the efforts of particle physicists is the phenomenon of parity violation.

It was resolved only by the discovery of parity violation in weak interactions.

The discovery of parity violation was a major contribution to high energy physics and the development of the Standard model.

However, the parity violation of weak interaction was discovered instead.

Hence parity violation is inherent in the weak interaction.

His recent research interests include studies of possible local parity violation in strong interaction in heavy ion collisions.
