To make a quark quintet, combine a trio and a duo.<\/p>\n

Exotic subatomic particles called pentaquarks contain five smaller particles called quarks and antiquarks. But those particles arent a simple clump of five constituents rattling around. Instead, the pentaquarks are molecule-like agglomerations<\/a> of a pair of smaller particles, each of which consists of either three quarks or a quark and an antiquark, scientists report in the June 7 Physical Review Letters<\/em>.<\/p>\n

First spotted in 2015 at the Large Hadron Collider in Geneva, pentaquarks were unlike anything seen before<\/a> (SN: 8\/8\/15, p. 8<\/em>). All previous known quark-containing particles were either baryons \u2014 particles such as protons and neutrons which contain three quarks \u2014 or mesons, which consist of one quark and one antiquark. But pentaquarks, with their five component particles, didnt fit into either of those categories.<\/p>\n

\u201cThere was no clear picture how these pentaquarks were built,\u201d says particle physicist Tomasz Skwarnicki of Syracuse University in New York, a coauthor of the study.<\/p>\n

Some scientists thought that the pentaquarks five constituents could mingle on an equal footingRead More \u2013 Source<\/strong><\/a>
