SUMMARY

The discussion centers on the Ds3*(2860)ˉ particle, identified as a meson composed of one charm antiquark and one strange quark, as reported by CERN LHC findings. It is confirmed that this particle exhibits spin3, which is atypical for mesons that usually possess spin0 or spin1. The total spin arises from the combination of the quarks' intrinsic spins and their orbital angular momentum, allowing for higher spin states without the necessity of additional quarks. This insight clarifies the nature of the Ds3* particle and its classification within particle physics.

PREREQUISITES
  • Understanding of particle physics concepts, specifically mesons and quark composition.
  • Familiarity with spin and angular momentum in quantum mechanics.
  • Knowledge of the Standard Model of particle physics.
  • Basic comprehension of CERN LHC experiments and their significance in particle discovery.
NEXT STEPS
  • Research the properties of mesons and their classifications in particle physics.
  • Study the implications of spin3 particles in quantum mechanics.
  • Explore the role of the CERN LHC in discovering exotic particles.
  • Investigate the interactions of charm and strange quarks in particle collisions.
USEFUL FOR

Particle physicists, researchers in quantum mechanics, and students studying the Standard Model will benefit from this discussion, particularly those interested in the properties and classifications of exotic particles like the Ds3*(2860)ˉ meson.

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...
 
Physics news on Phys.org
It is a meson with non-zero orbital angular momentum. Thus, the total spin of the two quarks plus the orbital angular momentum can add up to three without involving more quarks.

0 and 1 are just more frequent. There is nothing wrong with higher numbers for short-living particles.
