چکیده

New BABAR results on B mesons and quarkonia are presented: an analysis of B+ → X(3872)K+ and B0 → X(3872)K0 decays with X(3872) → J/ψπ+π−, a precise measurement of the B mass difference ΔmB = m(B0)−m(B+) and a study of hadronic transition between Υ mesons. Contributed to the Proceedings of Moriond QCD 2008, 3/08/2008—3/15/2008, La Thuile, Italy SLAC, Stanford Univesity, Stanford, CA 94309

Quarkonium spectroscopy and search for new states at BaBar

The BaBar experiment at the PEP-II B-factory gives excellent opportunities for the quarkonium spectroscopy. Investigation of the properties of new states like the X(3872), Y (3940) and Y (4260) are performed aiming to understand their nature. Recent BaBar results will be presented in this paper.

Nrqcd and Quarkonia

Quarkonia play an important role in several high energy experiments. The diversity, quantity and accuracy of the data still under analysis and currently being collected is impressive and includes: data on quarkonium formation from BES at the Beijing Electron Positron Collider (BEPC), E835 at Fermilab, and CLEO at the Cornell Electron Storage Ring (CESR); clean samples of charmonia produced in B...

Upsilon Decays

Bound upsilon states and their decays provide a unique laboratory for testing QCD, LQCD, and quarkonium potential models. I review recent results, some of which are significant improvements in precision over previous measurements and others are first-time observations. While most of the results presented are from CLEO III there are also notable contributions from BaBar and Belle who have just b...

Recent Developments in Heavy Quark and Quarkonium Production

Recent measurements of J/ψ production in ee colliders pose a challenge to the NRQCD factorization theorem for quarkonium production. Discrepancies between leading order calculations of color-octet contributions and the momentum distribution of J/ψ observed by Belle and BaBar are resolved by resumming large perturbative and nonperturbative corrections that are enhanced near the kinematic endpoin...
