For many years the discovery of the family of particles possible from combining quarks was limited to two quark (mesonic) and three-quark (baryonic) systems. In fact the word "quark" came from the James Joyce quote "three quarks for Muster Mark". Real progress has been made in recent years regarding other multiplicities for bound systems, with experimental and theoretical investigation of four-, five- and even six-quark systems. Strong evidence for the "d*" six-quark system (referred to as a hexaquark or dibaryon) has been obtained in the past decade from high-intensity neutron-proton scattering experiments with large acceptance detector systems. However, there is still a lot to learn and confirm regarding the d*. Recent results using electromagnetic beams will be presented. Added impetus for the d* programme has been provided by recent theoretical studies indicating the "d*" may potentially have impact on neutron star properties, influencing the equation of state, cooling mechanisms and maximum mass limits. The potential astrophysical implications of the d* will also be discussed.
Biography
Dan Watts started his career as a PhD and undergraduate at the University of Glasgow in the UK, followed by a research fellowship hosted at the University of Edinburgh. He is currently has a chair in hadron and nuclear physics at the University of York, UK. His pure physics research is carried out at the MAMI electron facility in Germany and Jefferson Laboratory in the USA. He also leads applied medical physics projects in the areas of quantum entangled PET imaging and new imaging methodologies for protontherapy.
