چکیده
We construct Spin(p+1, p+1) covariant Dp–brane bound states by using that the potentials in the RR sector of toroidically compactified type II supergravity transform as a chiral spinor of the T–duality group. As an application, we show the invariance of the zero–force condition for a probe D–brane under noncommutative deformations of the background, which gives a holographic proof of the stability of the corresponding field theory ground state under noncommutative deformations. We also identify the Spin(p+ 1, p+ 1) transformation laws by examining the covariance of the D–brane Lagrangians.

The D-dimensional (β, β ′)-two-parameter deformed algebra introduced by Kempf is generalized to a Lorentz-covariant algebra describing a (D + 1)-dimensional quan-tized spacetime. In the D = 3 and β = 0 case, the latter reproduces Snyder algebra. The deformed Poincaré transformations leaving the algebra invariant are identified. It is shown that there exists a nonzero minimal uncertainty in posi...

O(3, 1)L symmetry, the ground state baryons and antibaryons are assigned to the (12× 12× 12)Sym = 364-multiplet in the spin-flavor Ũ(12)SF symmetry. This multiplet includes, in addition to the ordinary 56-multiplet of the static SU(6)SF , the extra chiral 56 ′ and 70-multiplets, called “chiralons,” which are expected to exist with masses in 1 ∼ 2 GeV region. Their electro-magnetic properties, m...

We investigate the geometry of lightsheets comprised of null geodesics near a brane. Null geodesics which begin parallel to a brane a distance d away are typically gravitationally bound to the brane, so that the maximum distance from the geodesic to the brane never exceeds d. The geometry of resulting lightsheets is similar to that of the brane if one coarse grains over distances of order d. We...
متن کاملKaluza - Klein on the Brane
The M-theory interpretation of certain D=10 IIA p-branes implies the existence of worldvolume Kaluza-Klein modes which are expected to appear as 0-brane/p-brane bound states preserving 1/4 of the spacetime supersymmetry. We construct the corresponding solutions of the effective supergravity theory for p = 1, 4, and show that no such solution exists for p = 8.

We investigate, in a certain decoupling limit, the effect of having a constant C– field on the M–theory five–brane using an open membrane probe. We define an open membrane metric for the five–brane that remains non–degenerate in the limit. The canonical quantisation of the open membrane boundary leads to a noncommutative loop space which is a functional analogue of the noncommutative geometry t...
