Searching for supersymmetry

© duncan1890/ Getty Images

In the search for new physics, scientists are looking to supersymmetry to fill gaps in the Standard Model, and uncover deeper insights into the nature of matter, according to a study published in the Journal of High Energy Physics.

According to supersymmetry, elementary particles called quarks — the building blocks of matter — have super-partners that could help explain why particles have mass, and shed light on the origins of dark matter.

Using data from the Large Hadron Collider’s CMS detector, an international team of physicists, including researchers from the Moscow Engineering Physics Institute, searched for evidence of supersymmetric particles formed when protons collide at close to the speed of light.

A recent increase in the collider’s power, allowed the team to extend the range of collisions that the protons undergo and particles produced. Although the presence of supersymmetry remained elusive, their work has narrowed the search for new physics.
