Corrections to chiral dynamics of heavy hadrons: 1/M correction.
In earlier publications we have analyzed the strong and radiative decays of heavy hadrons in a formalism which incorporates both heavy-quark and chiral symmetries. In particular, we have derived a heavy-hadron chiral Lagrangian whose coupling constants are related by the heavy-quark flavor-spin symmetry arising from the QCD Lagrangian with infinitely massive quarks. In this paper, we reexamine ...
متن کاملFrom Hadrons to Nuclei: Crossing the Border
The study of nuclei predates by many years the theory of quantum chromodynamics. More recently, effective field theories have been used in nuclear physics to “cross the border” from QCD to a nuclear theory. We are now entering the second decade of efforts to develop a perturbative theory of nuclear interactions using effective field theory. This chapter describes the current status of these eff...

15 صفحه اولMeasurement of the branching ratio of the Z 0 into heavy quarks ∗
We measure the hadronic branching ratios of the Z boson into heavy quarks: Rb = ΓZ0→bb/ΓZ0→hadrons and Rc = ΓZ0→cc/ΓZ0→hadrons using a multi-tag technique. The measurement was performed using about 400,000 hadronic Z events recorded in the SLD experiment at SLAC between 1996 and 1998. The small and stable SLC beam spot and the CCD-based vertex detector were used to reconstruct bottom and charm ...
متن کاملConnecting Polyakov Loops to Hadrons
Importance sampling lattice simulations are able to provide vital information about the nature of the temperature driven phase transition for 2 and 3 color Yang-Mills theories with and without matter fields (see [ 5, 6] for 3 colors). At zero temperature the SU(N) Yang-Mills theory is asymptotically free, and the physical spectrum of the theory consists of a tower of hadronic states referred to...
