Puzzle Pieces: Results on bbbar and ccbar Spectroscopy and Decay

I discuss the theory of heavy baryon spectroscopy, emphasizing predictions which follow from light and heavy quark symmetries.

Summary and outlook presented at the 9th International Conference on the Structure of Baryons (BARYONS 2002), Jefferson Lab, March 3-8, 2002

I review some recent progress, open puzzles and future opportunities in heavy quarkonium physics in the framework of effective field theories

The experimental status of stable bound states made out of heavy quarks is reviewed. The need for a way to deal with the non-perturbative transitions involved calls for precision measurements on one hand, and for discovery of as yet undetected states to confirm predictions on the other. In this article, recent experimental contributions to heavy quarkonia spectroscopy and decay will be reviewed, mostly from data analyzed by the BES and CLEO collaborations. The most dramatic...

We review recent experimental results on lifetimes and hadronic decays of hadrons that contain $c$ and $b$ quarks. The theoretical implications of these results are also considered. An understanding of hadronic decays of heavy quarks is required to interpret the CP violating asymmetries in $B$ decays that will be observed in experiments planned for the near future.

With the discovery of new states in recent years, interest in spectroscopy has revived. Recent experimental results in heavy flavour spectroscopy are reviewed, including charmonium, bottomonium, charmed mesons and baryons and bottom mesons.

The status of heavy-quark decays as of summer 1999 is reviewed. New measurements of semileptonic B decays from LEP and from CLEO are reported and the status of determining the CKM parameters |Vcb| and |Vub| is assessed. Rare charmless hadronic B decays are reviewed, including the first observation of B->pi pi from CLEO. First attempts to measure CP asymmetries in rare decays are described. The implications of all of the data for our understanding of the Standard Model are bri...

Measurements of heavy flavor production and decay have featured prominently in the early results from the four large LHC experiments: ALICE, ATLAS, CMS, and LHCb. These results provide tests of QCD models in a new energy region and point the way toward future measurements of CP violation and searches for new physics. An overview of open heavy flavor studies is presented here, focusing on how the new measurements extend our knowledge of this area of physics. Heavy quarkonia st...

In the past few years the field of hadron spectroscopy has seen renewed interest due to the pubblication, initially mostly from B-Factories, of evidences of states that do not match regular spectroscopy, but are rather candidates for bound states with additional quarks or gluons. A huge effort in understanding the nature of this new states and in building a new spectroscopy is ongoing. This report reviews the experimental and theoretical state of the art on heavy quarkonium e...

We review the new results on the heavy flavor baryons and on the pentaquarks.
