quarkonia in a sentence

"quarkonia" in Chinese  
  1. CLEO decided to study the various bottom and charm quarkonia states and charm mesons.
  2. Quarkonia are bound states of heavy flavour quarks ( charm or bottom ) and their antiquarks.
  3. Work is also being done on calculations of such properties as widths of quarkonia states and transition rates between the states.
  4. Grasping the wealth of experimental results requires understanding the medium modification of quarkonia and disentangling hot and cold-matter effects.
  5. An early, but still effective, technique uses models of the " effective " potential to calculate masses of quarkonia states.
  6. It's difficult to find quarkonia in a sentence.
  7. However, the speed of the charm and the bottom quarks in their respective quarkonia is sufficiently smaller, so that relativistic effects affect these states much less.
  8. Quarkonia have been suggested as a diagnostic tool of the formation of the quark gluon plasma : both disappearance and enhancement of their formation depending on the yield of heavy quarks in plasma can occur.
  9. The ALICE forward muon spectrometer studies the complete spectrum of heavy quarkonia ( J / ?, ?2, ?, ?2, ?2 2 ) via their decay in the ? + ? channel.
  10. Indeed, in heavy-ion collisions, such a suppression has been interpreted as a sequential melting of quarkonia states, depending on their binding energy and the temperature of the QGP created in these collisions.
  11. However-as the collision energy increases-so does the number of charm-anticharm quarks that can form bound states, and a balancing mechanism of recombination of quarkonia may appear as we move to higher energies.
  12. The " melting " of quarkonia into the QGP manifests itself in the suppression of the quarkonium yields compared to the production without the presence of the QGP . The search for quarkonia suppression as a QGP signature started 25 years ago.
  13. The " melting " of quarkonia into the QGP manifests itself in the suppression of the quarkonium yields compared to the production without the presence of the QGP . The search for quarkonia suppression as a QGP signature started 25 years ago.
  14. It is popular because it allows for accurate predictions of quarkonia parameters without a lengthy lattice computation, and provides a separation between the short-distance " Coulombic " effects and the long-distance " confinement " effects that can be useful in understanding the quark / anti-quark force generated by QCD.
  15. Two types of quarkonia have been extensively studied : charmonia, which consist of a charm quark and an anti-charm, and bottomonia made of a bottom and an anti-bottom quark . Charm and anticharm quarks in the presence of the Quark Gluon Plasma, in which there are many free colour charges, are not able to see each other any more and therefore they cannot form bound states.
