چکیده
Global fits to precision cosmological data which show that there is a dark energy component comprising about 2/3 of the total cosmological energy also hint that a dark energy with w = P/ρ < −1 is viable, even favored. Here we discuss implications of such a surprising w, including whether it jeopardizes vacuum stability. It appears to be secure in microscopic processes, but why bulk dark energy has not decayed spontaneously is mysterious.

Precision cosmological data hint that a dark energy with equation of state w = P/ρ < −1 and hence dubious stability is viable. Here we discuss for any w nucleation from Λ > 0 to Λ = 0 in a first-order phase transition. The critical radius is argued to be at least of galactic size and the corresponding nucleation rate glacial, thus underwriting the dark energy’s stability and rendering remote an...

The use of the AdS/CFT correspondence to arrive at quiver gauge field theories is dicussed, focusing on the orbifolded case without supersymmetry. An abelian orbifold with the finite group Zp can give rise to a G = SU (N) p gauge group with chiral fermions and complex scalars in different bi-fundamental representations of G. The precision measurements at the Z resonance suggest the values p = 1...

The experimental potential of e+e− Linear Colliders to explore the properties of supersymmetric particles is reviewed. High precision measurements of masses, spin-parity, gauge quantum numbers, couplings and mixings, production and decay properties will be possible in a clean environment. These achievements will allow the underlying supersymmetry breaking scheme to be revealed, the parameters o...

We review the Standard Model prediction of the τ lepton g−2 presenting updated QED and electroweak contributions, as well as recent determinations of the leading-order hadronic term, based on the low energy e + e − data, and of the hadronic light-by-light one.
