HIGH ENERGY PHYSICS SEMINAR TODAY
Monday November 16, 2015
Speaker: Jon Rosner (UChicago)
Title: Tetraquarks and Pentaquarks
Abstract: The LHCb Collaboration at CERN have reported two new structures in the J/psi p mass spectrum: a broad one at 4380 MeV and a narrow one at 4450 MeV. These are candidates for "pentaquarks" (states of four quarks and an antiquark). Work describing the interpretation of the narrow state as a molecule of a charmed baryon and anticharmed meson is described. A brief historical survey of the forerunners of these states, exotic mesons dubbed "tetraquarks", is also given.
