IU physicist leads discovery of new particle: 'four-flavored' tetraquark

Research led by Indiana University physicist Daria Zieminska has resulted in the first detection of a new form of elementary particle: the “four-flavored” tetraquark. Zieminska, a senior scientist in the IU Bloomington College of Arts and Sciences’ Department of Physics, is a lead member of the team responsible for the particle’s detection by the DZero Collaboration at the U.S. Department of Energy’s Fermi National Laboratory, which announced the discovery Feb. 25. She also delivered the first scientific seminar on the particle and is an author on a paper submitted to Physics Review Letters, the premier journal in physics, describing the tetraquarks’ observation.”
