Quarkonium from the Fifth Dimension
Adding fundamental matter of mass mQ to N = 4 Yang Mills theory, we study quarkonium, and “generalized quarkonium” containing light adjoint particles. At large ’t Hooft coupling the states of spin ≤ 1 are anomalously light (Kruczenski et al., hep-th/0304032). We examine their form factors, and show these hadrons are unlike any known in QCD. By a traditional yardstick they appear infinite in siz...
متن کاملFifth Force from Fifth Dimension
Using a novel coordinate system, we rederive the eld equations and equations of motion for 5-dimensional relativity in the general case where the metric can depend on all 5 coordinates (i.e., Kaluza-Klein theory without the cylinder restriction). We show that in general the fth dimension produces a new dynamical force in 4-dimensional spacetime. This timelike fth force is proportional to the 4-...
متن کاملMultiflavour excited mesons from the fifth dimension
We study the Regge trajectories and the quark-antiquark energy in excited hadrons composed by different dynamical mass constituents via the gauge/string correspondence. First we exemplify the procedure in a supersymmetric system, D3-D7, in the extremal case. Afterwards we discuss the model dual to large-Nc QCD, D4-D6 system. In the latter case we find the field theory expected gross features of...
متن کاملInteracting with the Fifth Dimension
The use of the scalar-Einstein field equations and their solutions seems to have gone through four, perhaps related, stages. In the first stage [1] solutions were sought which it was hoped would represent an elementary particle such as a meson. How the scalar field decays from such solutions might effect the Yukawa potential has been discussed by Roberts [2]. In the second stage it was noticed ...
متن کاملShortcuts in the fifth dimension
If our Universe is a three-brane embedded in a five-dimensional antideSitter spacetime, in which matter is confined to the brane and gravity inhabits an infinite bulk space, then the causal propagation of luminous and gravitational signals is in general different. A gravitational signal traveling between two points on the brane can take a “shortcut” through the bulk, and appear quicker than a p...
