چکیده

We consider a 2 + 1-dimensional SU(N) lattice gauge theory in an axial gauge with the link field U 1 set equal to one. The term in the Hamiltonian containing the square of the electric field in 1-direction is non-local. Despite this non-locality, we show that weak-coupling perturbation theory in this term gives a finite vacuum-energy density to second order, and suggest that this property holds to all orders. Heavy quarks are confined, the spectrum is gapped, and the space-like Wilson loop has area decay.

Penta-quark (5Q) baryons are studied using anisotropic lattice QCD for high-precision measurement of temporal correlators. A non-NK-type interpolating field is employed to study the 5Q states with J = 1/2 and I = 0. In J = 1/2 channel, the lowest-lying state is found at m5Q ≃ 2.25 GeV, which is too massive to be identified as the Θ(1540). In J = 1/2 channel, the lowest-lying state is found at m...

We present measurements of time-dependent asymmetries in decays of neutral B mesons to the final states B 0 → ρ ± π ∓. Measurements are based on a 140 f b −1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e + e − collider.

The rare decay B0 → φφ can occur only via penguin annihilation topology in the standard model. We calculate this channel in the perturbative QCD approach. The predicted branching ratio is very small at (10−8). We also give the polarization fractions, which shows that the transverse polarization contribution is comparable to the longitudinal one, due to a big transverse contribution from factori...
