“…; N. For dynamic spacetime, the bulk gravitational field includes, besides the assumed world volume localized graviton, world volume gravi-vector fields, denoted X i , related to the broken space translation directions. Indeed, these vector fields combine with the Nambu-Goldstone bosons to become world volume (brane localized) massive Proca fields [4][5][6]. In the case of compact isotropic extra dimensions, for a flexible brane, one whose brane tension is less than the bulk gravitational scale, the coupling of the higher gravitational Kaluza-Klein modes to standard model fields is exponentially suppressed [6].…”

“…II of this paper, the construction of the effective action is briefly reviewed [4]. Since the embedded brane spontaneously breaks the bulk Poincaré symmetries the method of nonlinear realizations has been used to determine the form of the effective action of the brane and its coupling to the standard model fields in a model independent manner.…”

Brane world oscillations manifest themselves as massive vector gauge fields. Their coupling to the standard model is deduced using the method of nonlinear realizations of the spontaneously broken higher dimensional space-time symmetries. Brane vectors are stable and weakly interacting and therefore escape particle detectors unnoticed. LEP and Tevatron data on the production of a single photon in conjunction with missing energy are used to delineate experimentally excluded regions of brane vector parameter space. The additional region of parameter space accessible to the LHC as well as a future lepton linear collider is also determined by means of this process.

We investigate the topological properties of N f = 2 + 1 QCD with physical quark masses, at temperatures around 500 MeV. With the aim of obtaining a reliable sampling of topological modes in a regime where the fluctuations of the topological charge Q are very rare, we adopt a multicanonical approach, adding a bias potential to the action which enhances the probability of suppressed topological sectors. This method permits to gain up to three orders magnitude in computational power in the explored temperature regime. Results at different lattice spacings and physical spatial volumes reveal no significant finite size effects and the presence, instead, of large finite cut-off effects, with the topological susceptibility which decreases by 3-4 orders of magnitude while moving from a ≃ 0.06 fm towards the continuum limit. The continuum extrapolation is in agreeement with previous lattice determinations with smaller uncertainties but obtained based on ansatzes justified by several theoretical assumptions. The parameter b 2 , related to the fourth order coefficient in the Taylor expansion of the free energy density f (θ), has instead a smooth continuum extrapolation which is in agreement with the dilute instanton gas approximation (DIGA); moreover, a direct measurement of the relative weights of the different topological sectors gives an even stronger support to the validity of DIGA.

Brane vector dynamics from embedding geometry

A Kaluza-Klein decomposition of higher dimensional gravity is performed in the flexible brane world scenario and the properties of the extra vectors resulting from this decomposition are explored. These vectors become massive due to a gravitational Higgs mechanism in which the brane oscillation Nambu-Goldstone bosons become the longitudinal component of the vector fields. The vector mass is found to be proportional to the exponential of the vacuum expectation value of the radion (dilaton) field and as such its magnitude is model dependent. Using the structure of the embedding geometry, the couplings of these vectors to the Standard Model, including those resulting from the extrinsic curvature, are deduced. As an example, we show that for 5D space-time the geometry of the bulk-brane world, either intrinsic or extrinsic, only depends on the extra vector and the 4D graviton. The connection between the embedding geometry and coset construction by non-linear realization is also presented.
