The WG3 part of the write-up of the workshop will be discussed.

Detectors are getting ready and MEG will start data taking this year. The current
status and prospects will be presented.

hundred fold improvement of the sensitivity on a heavy target

I discuss the lepton universality in M->l nu (with M = pi, K, B) and in hadronic and
leptonic tau decays as a tool to probe New Physics.

The possibility for an improved precision measurement of the ratio of
leptonic decay widths of the charge Kaon with the Na48/2 apparatus is 
discussed in the light of the interest which such channel acquired as
a search for New Physics

Tests of lepton universality based on the latest measurements by Babar and
Belle of the tau mass and lifetime are discussed.

In the past few months proposals for improved measurements of the
pi->e+nu / pi->mu+nu branching ratio have been approved at TRIUMF and PSI.
Details will be presented.

I will give an overview of the status of the muon g-2 upgrade, the goals and
prospects.

I discuss a novel and very predictive supersymmetric GUT scenario 
  where the exchange of SU(2)_L triplet generates both neutrino masses
  and soft SUSY breaking terms.  The phenomenological viability and 
  experimental signatures are discussed.

We discuss the impact of neutrino masses and mixings on 
LFV processes within the context of the SUSY Seesaw, where 
the CMSSM is extended by 3 right-handed (s)neutrinos.
We focus on the sensitivity of tau and muon LFV decays on 
the most relevant parameters. Compatibility with neutrino 
data, LFV and EDM bounds, and requiring successful 
baryogensis via thermal leptogenesis leads to strong 
constraints on the Seesaw parameters, for the studied SUSY 
benchmark points. We particularly emphasise the interesting 
relation between theta_13 and LFV muon decays.

recent developments

This talk will cover the main approaches taken in atomic and nuclear physics to
measure TRV. In particular, the search for an electric dipole moment of atoms. At the
Kernfysisch Versneller Instituut an experimental facility is being created to produce
radioactive isotopes that have favorable properties for TRV studies. The outline of
this facility will be presented.

We analyse the complementarity between Lepton Flavour Violation (LFV) and LHC
experiments in probing the Supersymmetric (SUSY) Grand Unified Theories (GUT) when
neutrinos got a mass via the see--saw mechanism. Our analysis is performed in an
SO(10) framework, where at least one neutrino Yukawa coupling is necessarily as large
as the top Yukawa coupling. Our study thoroughly takes into account the whole RG
running, including the GUT and the right handed neutrino mass scales, as well as the
running of the observable neutrino spectrum. We find that the upcoming (MEG,
SuperKEKB) and future (PRISM/PRIME, Super Flavour factory) LFV experiments will be
able to test such SUSY framework for SUSY masses to be explored at the LHC and, in
some cases, even beyond the LHC sensitivity reach.
