Russian scientists announce discovery of new particle at Large Hadron Collider

Russian scientists participating in the LHCb collaboration at the Large Hadron Collider have announced the discovery of a new particle — the exotic tetraquark Tcс+. This is a new form of matter, a press release published on the CERN website said.
Tcc+ tetraquark is the only particle known to science that consists of four quarks, two of which are charmed (c-quarks) with no presence of charmed antiquarks.
The charm stands for a flavour quantum number that characterizes the type of the quark (there are six different “types” of quarks known in total). At the same time, the lifetime of a new tetraquark is approximately 10-500 times longer than that of particles with a similar mass, which makes Tcc + tetraquark the longest-lived record holder.
