Physicists discover new class of pentaquarks

Posted by in category: particle physics

Tomasz Skwarnicki, professor of physics in the College of Arts and Sciences at Syracuse University, has uncovered new information about a class of particles called pentaquarks. His findings could lead to a new understanding of the structure of matter in the universe.

Assisted by Liming Zhang, an associate professor at Tsinghua University in Beijing, Skwarnicki has analyzed data from the Large Hadron Collider beauty (LHCb) experiment at CERN’s Large Hadron Collider (LHC) in Switzerland. The experimental physicist has uncovered evidence of three never-before-seen pentaquarks, each divided into two parts.

“Until now, we had thought that a pentaquark was made up of five [called quarks], stuck together. Our findings prove otherwise,” says Skwarnicki, a Fellow of the American Physical Society.
