Lepton Flavour Violation
Oral presentation
In previous works (JHEP03(2012)100, JHEP09(2012)015), we have highlighted that the Higgs and Z-mediated penguin diagrams contributing to lepton flavour violating (LFV) observables like tau->3mu are strongly enhanced in the supersymmetric inverse seesaw model. It has recently been pointed out that an error in the literature for the Z-penguins form factors would lead to a non-physical...

Lepton Flavour Violation
Oral presentation
In the inverse seesaw, the smallness of the neutrino masses is related to the smallness of a lepton number violating mass term whilst the seesaw scale is naturally close to the TeV. This allows for large effects in lepton flavor and universality violating observables as was previously demonstrated. With the ongoing and planned measurements of the Higgs boson properties at the LHC, we found...

Lepton Flavour Violation
Oral presentation
We update previous analyses of the Zee-Babu model in the light of new neutrino and LFV data, and the LHC results. We also analyse the possibility of accommodating the deviations in Higgs the diphoton channel hinted by the LHC experiments, and the stability of the scalar
potential. We find that neutrino oscillation data and low energy constraints are still compatible with masses of the extra...

Lepton Flavour Violation
Oral presentation
Within an effective field theory framework, I will discuss the possibility to discriminate between different operators that contribute to lepton flavour violating tau decays. Correlations among decay rates in different channels as well as differential distributions in many-body decays are considered. Recent developments in the determination of the hadronic form factors for tau -> mu pi...

Lepton Flavour Violation
Oral presentation
A general overview of the connection between radiative LFV decays, neutrino and LHC data in the context of SUSY seesaws will be given. The impact of the measurement of the reactor neutrino mixing angle and the most recent bounds on rare LFV decays will be discussed.

Lepton Flavour Violation
Oral presentation
Recent results and prospects for precision tests of the Standard Model in kaon decay in flight experiments at CERN are presented. A measurement of the ratio of leptonic decay rates of the charged kaon at a 0.4% precision constrains the parameter space of new physics models with extended Higgs sector, a fourth generation of quarks and leptons or sterile neutrinos.

Lepton Flavour Violation
Oral presentation
The MEG experiment in search for the lepton-flavour violating muon decay mu -> e gamma completed its data-taking in August 2013.
The new data in 2013 are now being analysed together with the data taken in 2012 with improved analysis algorithms, which will eventually double the total data statistics.
The latest result from the search analysis will be presented.
The status and prospect of...

Lepton Flavour Violation
Oral presentation
Mu2e will search for coherent, neutrino-less conversion of muons into electrons in the field of a nucleus with a sensitivity improvement of a factor of 10,000 over existing limits. Such a lepton flavor-violating reaction probes new physics at a scale inaccessible with direct searches at either present or planned high energy colliders. The experiment both complements and extends the current...

Lepton Flavour Violation
Oral presentation
The COMET Experiment at J-PARC aims to search for the lepton-flavour violating process of muon to electron conversion in a muonic atom, $\mu^{-}N \rightarrow \mathrm{e}^{-}N$, with a branching-ratio sensitivity of $6 \times 10^{−17}$, in order to explore the parameter region predicted by most well-motivated theoretical models beyond the Standard Model. The need for this sensitivity places...

Lepton Flavour Violation
Oral presentation
A new experiment to search for muon to electron conversion in nuclear field, DeeMe, is proposed at J-PARC Materials and Life Science Experimental Facility (MLF). This experiment will be carried out at a brand-new beamline (H-Line) which will be constructed at J-PARC MLF Muon Science Establishment (MUSE).
Muonic atoms formed in a muon production target will be utilized. The signal electrons...
