Spin correlations at the Z peak. A probe to the Z′ mass
1992
Abstract The interactions of a new heavy gauge boson are fixed by its coupling to matter and by its mass and its mixing with the Z 0 . Until now LEP has only constrained the Z′ mixing. However, there is one observable (and only one), the P - and T -odd transverse-normal spin correlation in ττ production, which fully and independently of its mixing measures the Z′ mass at the Z peak. For M z′ ∼ 130 GeV the Z′ contribution to this observable is typically of the same order as the standard model contribution.

Collider aspects of flavour physics at high Q
2008
This chapter of the 'Flavor in the era of LHC' workshop report discusses flavor-related issues in the production and decays of heavy states at the LHC at high momentum transfer Q, both from the experimental and the theoretical perspective. We review top quark physics, and discuss the flavor aspects of several extensions of the standard model, such as supersymmetry, little Higgs models or models with extra dimensions. This includes discovery aspects, as well as the measurement of several properties of these heavy states. We also present publicly available computational tools related to this topic. © Springer-Verlag / Società Italiana di Fisica 2008.
