    Meson
In summary, there has been news on Ds3*(2860)ˉ from the CERN LHC regarding spin3 particles made from quarks. The Ds3* particle is a meson with non-zero orbital angular momentum, which means that the total spin of the two quarks plus the orbital angular momentum can add up to three without involving more quarks. While spin0 and spin1 are more common for mesons, there is nothing wrong with higher numbers for short-living particles.

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...

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

1. What is a Ds3*(2860)ˉ Meson?

A Ds3*(2860)ˉ Meson is a type of subatomic particle that is composed of quarks. Specifically, it is a meson made up of a charm quark and an anti-strange quark. It was first observed at CERN's Large Hadron Collider (LHC) in 2010.

2. How was the Ds3*(2860)ˉ Meson discovered at the LHC?

The Ds3*(2860)ˉ Meson was discovered by analyzing data from collisions at the LHC. Scientists look for unique patterns in the data that indicate the presence of a new particle. In this case, the Ds3*(2860)ˉ Meson was identified by its decay products, which were observed in the detector.

3. What is the significance of the Ds3*(2860)ˉ Meson?

The discovery of the Ds3*(2860)ˉ Meson helps to further our understanding of the fundamental building blocks of matter. It adds to the current knowledge of quarks and their interactions. This particle also provides new opportunities for studying the strong nuclear force, which holds quarks together.

4. How does the Ds3*(2860)ˉ Meson fit into the Standard Model of particle physics?

The Standard Model is a theory that describes the fundamental particles and their interactions. The Ds3*(2860)ˉ Meson fits into this model as it is made up of quarks, which are one of the building blocks of matter according to the Standard Model. Its discovery provides further evidence for the accuracy of this theory.

5. What future research is being done on the Ds3*(2860)ˉ Meson?

Scientists continue to study the properties of the Ds3*(2860)ˉ Meson, such as its mass, spin, and decay modes. This research can help us better understand the dynamics of quarks and their interactions. Additionally, further studies of this particle may provide insight into the behavior of other mesons and the strong nuclear force.
