For 1 ≤ d ≤ k, let Kk/d be the graph with vertices 0, 1, · · · , k − 1, in which i ∼ j if d ≤ |i − j| ≤ k − d. The circular chromatic number χc(G) of a graph G is the minimum of those k/d for which G admits a homomorphism to Kk/d. The circular clique number ωc(G) of G is the maximum of those k/d for which Kk/d admits a homomorphism to G. A graph G is circular perfect if for every induced subgra...

In this paper we examine the 4-dimensional effective theory for the light KaluzaKlein (KK) modes. Our main interest is in the interaction terms. We point out that the contribution of the heavy KK modes is generally needed in order to reproduce the correct predictions for the observable quantities involving the light modes. As an example we study in some detail a 6-dimensional Einstein-Maxwell t...

The Randall-Sundrum framework provides an appealing solution to both the gauge hierarchy and the flavour problem. The model with enlarged custodial symmetry is consistent with electroweak precision observables for Kaluza-Klein (KK) scales as low as (2−3)TeV, so that the lowest-lying KK modes could be observed at the LHC. The presence of the heavy KK gauge bosons induces new tree level contribut...

We study the bounds states of the Kaluza-Klein (KK) excitations of quarks in models of Universal Extra Dimensions. Such bound states may be detected at future lepton colliders in the cross section for the pair-production of KKquarks near threshold. For typical values of model parameters, we find the “KK-quarkonia” have widths in the 10-100 MeV range, and production cross sections of order a few...

The coupled channel model of the a0(980) and a0(1450) resonances has been constructed using the separable πη and KK interactions. We have shown that two S–matrix poles corresponding to the a0(980) meson have significantly different widths in the complex energy plane. The KK to πη branching ratio, predicted in our model near the a0(1450) mass, is in agreement with the result of the Crystal Barre...

A graph G is r-ramsey-minimal with respect to Kk if every rcolouring of the edges of G yields a monochromatic copy of Kk, but the same is not true for any proper subgraph of G. In this paper we show that for any integer k ≥ 3 and r ≥ 2, there exists a constant c > 1 such that for large enough n, there exist at least c 2 non-isomorphic graphs on at most n vertices, each of which is r-ramsey-mini...

We study Schwinger pair creation of charged Kaluza-Klein particles from a static KK electric field. We find that the gravitational backreaction of the electric field on the geometry – which is incorporated via the electric KK Melvin solution – prevents the electrostatic potential from overcoming the rest mass of the KK particles, thus impeding the tunneling mechanism which is often thought of a...

A structural description is given of the separable C∗-algebras that are contractible in KK-theory or E-theory. Subsequently it is shown that two separable C∗-algebras, A and B, are KK-equivalent if and only if there is a bundle of separable C∗-algebras over [0, 1] which is piecewise trivial with no more than six points of non-triviality such that the kernel of each fiber map is KK-contractible,...
