We review some theoretical and experimental issues in unparticle physics, focusing mainly on collider signatures.

Experiments are planned to improve the sensitivity of μ − e conversion from the current ∼ 10 to ∼ 10 − 10. If the muon (bound to the nucleus) could be polarised, a spin asymmetry of the final state electron is sensitive to CP violating phases on lepton flavour violating operators. This is similar to extracting phases from asymmetries in the final state spin and phase space distributions of μ → ...

Using a correlation inequality of Contucci and Lebowitz for spin glasses, we demonstrate existence of the thermodynamic limit for short-ranged spin glasses, under weaker hypotheses than previously available, namely without the assumption of the annealed bound.

We point out a Z2 × Z2 symmetry which characterizes uniquely the phenomenologically successful tripartite form leading to a tri-bimaximal mixing in the neutrino mass matrix. We impose this symmetry in a set up including the charged leptons and find that it can accommodate all the possible patterns of lepton masses in the framework of type-I and type-II seesaw mechanism. We also discuss the poss...
