Critical phenomena arise in a wide variety of physical systems. Classi cal examples are the
liquid-vapour critical point or the paramagnetic ferromagnetic transition. Further examples …

Motivated by recent works of Sen [hep-th/0203211, hep-th/0203265] and Gibbons [hep-
th/0204008], we study the evolution of a flat and homogeneous universe dominated by …

We perform a detailed analysis of several μ–τ lepton flavour violating (LFV) processes,
namely τ→ μX (X= γ, e+ e−, μ+ μ−, ρ, π, η, η′), Z→ μτ and Higgs boson decays into μτ. First …

These are notes of my lectures held at the first School & Workshop on Logarithmic
Conformal Field Theory and its Applications, September 2001 in Tehran, Iran. These notes …

We study two-dimensional conformal field theories generated from a “symplectic fermion”—a
free two-component fermion field of spin one—and construct the maximal local …

A comprehensive introduction to logarithmic conformal field theory, using an algebraic point
of view, is given. A number of examples are explained in detail, including the c=-2 triplet …

The local logarithmic conformal field theory corresponding to the triplet algebra at c=-2 is
constructed. The constraints of locality and duality are explored in detail, and a consistent …

A bstract Logarithmic conformal field theories have a vast range of applications, from critical
percolation to systems with quenched disorder. In this paper we thoroughly examine the …

The fusion products of admissible representations of the su (2) WZW model at the fractional
level k=− 4/3 are analysed. It is found that some fusion products define representations for …

Motivated by the possible experimental opportunities to test quantum gravity via its effects on
high-energy neutrinos propagating through space-time foam, we discuss how to incorporate …
