Dual Worlds

The letter Magnetic S-parameter by Francesco Sannino has just been accepted for publication on the prestigious Physical Review Letters journal of the American Physical Society.

Quantum Chromodynamics (QCD) is the theory describing one of the fundamental forces of Nature, i.e., the one responsible for holding together the quarks inside the proton. For over four decades, scientists have tried to understand its intricate dynamics using analytical methods as well as first principle computer simulations. Despite the many successes a complete understanding is still missing. In his work, Sannino has shed new light on such a complicated dynamics by using a modern version of the Dirac’s famous idea of electro-magnetic duality.  In the published article he computed analytically physically relevant quantities which are accessible only via future expensive supercomputer simulations.

The introduced method is general, testable, and can be extended to understand the dynamics of novel theories which may play a fundamental role in explaining the origin of bright and dark matter in the universe.
