There has been news lately on Ds3*(2860)ˉ from the CERN LHC of spin3 particles made from quarks. One example at http://news.yahoo.com/exotic-particle-could-help-explain-holds-matter-together-111405002.html
The article says: " The Ds3* particle is made of one charm antiquark and one strange quark." and later refers to it as a Meson which would normally only be spin0 or spin1.
Do they mean it has only these two quarks or that it contains these two quarks and maybe more? A bit confused...
