Lepton Flavour and Number Violation in Left-Right Symmetrical Models

We discuss lepton flavour and number violating processes induced in the production and decay of heavy right-handed neutrinos at the Large Hadron Collider. Such particles appear in Left-Right symmetrical extensions of the Standard Model as the "messengers"' of neutrino mass and may have masses of order TeV, potentially accessible at the LHC. We determine the expected sensitivity on the right-handed neutrino mixing matrix, as well as on the right-handed gauge boson and heavy neutrino masses, and compare the results with low-energy probes such as searches for mu-e conversion in nuclei and neutrinoless double beta decay.

Weak measurement: a new type of quantum measurement and its experimental implications

We will discuss the notion of a ‘weak measurement’, originally introduced by Aharonov et al and carefully analyzed by Duck et al. This technique opens up new experimental possibilities for exploring quantum phenomena. It has already been used to measure the spin Hall effect of light and to measure photon ‘trajectories’ in a two slit interference set up, traditionally deemed to be impossible without destroying the interference effects. We will discuss the theoretical basis for the experimental technique and propose new experiments to explore foundational issues, throwing new light on the Bohm interpretation.
