Exotic particles containing five quarks discovered at the Large Hadron Collider

Good Morning PO1 Tony Holland and thank you for a great Physics story for today! Just when one thinks one knows everything about the periodic table, Physicists find and name a new particle...subatomic at that! LOL! Thank you for this extremely great Post on "Hadrons", "Baryons" and "Mesons"!

Thank you for the interesting scientific share.
