Fifth 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 کاملQuarkonium 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 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 کاملInteracting with the Fifth Dimension
Some new five dimensional minimal scalar-Einstein exact solutions are presented. These new solutions are tested against various criteria used to measure interaction with the fifth dimension.
