New quantum article found, a combination of four quantum basic particles:-http://phys.org/news/2016-02-scientists-subatomic-particle.html-"Physicists have discovered a new elementary particle—the latest member to be added to the exotic species known as tetraquarks. -" The discovery was made by scientists - including Lancaster's Professor Iain Bertram - involved in the DZero international collaboration at Fermilab, the US Government's laboratory specialising in high-energy particle physics.-"Professor Bertram said: "It is exciting to discover a new and unusual particle that will help us understand the strong interaction- one of the four known fundamental interactions in physics." -"DZero is one of two experiments at Fermilab's Tevatron collider. Although the Tevatron was retired in 2011, the experiments continue to analyse billions of previously recorded events from its collisions. -"The tetraquark observation came as a surprise when DZero scientists first saw hints in July 2015 of the new particle, called X(5568), named for its mass—5568 megaelectronvolts.-"Professor Bertram worked on the analysis, developing the model used to simulate the X(5568). -"Quarks are point-like elementary particles that typically come in packages of two or three, the most familiar of which are the proton and neutron (each is made of three quarks). -"There are six types, or "flavours," of quark to choose from: up, down, strange, charm, bottom and top. Each of these also has an antimatter counterpart.-"While all other observed tetraquarks contain at least two of the same flavor, X(5568) has four different flavors - up, down, strange and bottom."-Comment: This particle is simply a combination of known basic quarks with higher energy from the combination.
