Exotic Quarkonia from Lattice QCD
We present non-perturbative results for the spectrum of heavy quarkonia. Using an anisotropic formulation of Lattice QCD we achieved an unprecedented control over statistical and systematic errors. We also study relativistic corrections to the leading order predictions for heavy hybrids and conventional bound states. † CP-PACS Collaboration: A. Ali Khan, S. Aoki, R. Burkhalter, S. Ejiri, M.

متن کاملLattice QCD at finite T and μ
Recent results of lattice QCD at finite temperature and density are reviewed. At vanishing density the transition temperature, the equation of state and hadron properties are discussed both for the pure gauge theory and for dynamical staggered, Wilson and overlap fermions. The second part deals with finite density. There are recent results for full QCD at finite temperature and moderate density...
متن کاملDetermining hybrid content of heavy quarkonia using lattice nonrelativistic QCD
Using lowest-order lattice NRQCD to create heavy meson propagators and applying the spin-dependent interaction, cB −g 2mq ~σ · ~ B, at varying intermediate time slices, we compute the off-diagonal matrix element of the Hamiltonian for the quarkonium-hybrid two-state system. Diagonalizing this two-state Hamiltonian, the admixture of hybrid (|QQ̄g〉) in the ground state is found. We present results...
متن کاملLattice QCD results at finite T and μ
We propose a method to study lattice QCD at finite temperature (T) and chemical potential (µ). We test the method and compare it with the Glasgow method using n f =4 staggered QCD with imaginary µ. The critical endpoint (E) of QCD on the Re(µ)-T plane is located. We use n f =2+1 dynam-ical staggered quarks with semi-realistic masses on L t =4 lattices. Our results are based on O(10 3 − 10 4) co...
متن کاملB(0)-B(0) mixing in unquenched lattice QCD.
We present an unquenched lattice calculation for the B(0)-B(0) transition amplitude. The calculation, carried out at an inverse lattice spacing 1/a=2.22(4) GeV, incorporates two flavors of dynamical quarks described by the O(a)-improved Wilson fermion action and heavy quarks described by nonrelativistic QCD. Particular attention is paid to the uncertainty that arises from the chiral extrapolati...
