Universal Extra Dimensions and b → sγ
We analyze the effect of flat universal extra dimensions (i.e., extra dimensions accessible to all SM fields) on the process b → sγ. With one Higgs doublet, the dominant contribution at one-loop is from Kaluza-Klein (KK) states of the charged would-be-Goldstone boson (WGB) and of the top quark. The resulting constraint on the size of the extra dimension is comparable to the constraint from T pa...
متن کاملMinimal Universal Extra Dimensions
Highly degenerate spectra associated with universal extra dimensions (UED) provide an interesting phenomenology not only from the point of view of cosmology and astrophysics, but also for colliders. We study these exotic signals for the simplest case, called minimal UED, where it is natural to find slow charged particles, displaced vertices, tracks with non-vanishing impact parameters, track ki...
متن کاملOn Minimal Non-b-groups
A finite group G is called a B-group if every proper subgroup of G is either normal or abnormal in G. In this paper the authors classify the non-B-groups whose proper subgroups are all B-groups.
متن کاملExclusive B → K 1 l + l − decay in model with single universal extra dimension
Decay rate and forward-backward asymmetries in B → K1ll , K1 is the axial vector meson, are calculated in the universal extra dimension (UED) model. The dependence of these physical quantities on the compactification radius R, the only unknown paramter in UED model, is studied and it is shown that zero of forward-backward asymmetry is sensitive to the UED model, therefore they can be very usefu...
متن کاملUniversal Z-lattices of Minimal Rank
Let UZ(n) be the minimal rank of n-universal Z-lattices, by which we mean positive definite Z-lattices which represent all positive Z-lattices of rank n. It is a well known fact that UZ(n) = n + 3 for 1 ≤ n ≤ 5. In this paper, we determine UZ(n) and find all n-universal lattices of rank UZ(n) for 6 ≤ n ≤ 8.
