None for ages then 5 all at once...

Nothing over-exciting though.

Study matter and its motion through spacetime...

None for ages then 5 all at once...

From LHCb experiment at CERN.

5 new composite particles (Omega-0 c)- uncharged Omega baryons with a charm quark. All on the same plot. All standard model (SM) elements and nothing to do with supersymmetry or anything else beyond the SM. Details at link.

Still useful though...
...
Dr Greig Cowan, of the University of Edinburgh, UK, who works on the LHCb experiment at Cern's LHC, said: "This is a striking discovery that will shed light on how quarks bind together. It may have implications not only to better understand protons and neutrons, but also more exotic multi-quark states, such as pentaquarks and tetraquarks."

Prof Tara Shears, of Liverpool University, who also works on the experiment, said: "These particles have been hiding in plain sight for years, but it has taken the exquisite sensitivity of the LHCb to bring them to our attention."
