Dr Stephane Lavignac (SPhT Saclay)28/07/2007, 14:00Flavor PhysicsParallel TalkStudies of leptogenesis and of lepton flavour violation are usually done in the framework of the type I seesaw mechanism, or assume dominance of one of the two (type I or type II) seesaw mechanisms. In this talk, we discuss the generic situation where both contributions to light neutrino masses can be comparable in size and are related by a left-right symmetry. We find qualitatively...Go to contribution page

Dr zurab tavartkiladze (Oklahoma State University)28/07/2007, 14:20Flavor PhysicsParallel TalkI'll discuss the scenario of inverted neutrino mass hierarchies. Due to symmetry arguments, the model has several predictions. The solar mixing angle is correlated to the third leptonic mixing angle such that we get $\theta_{13}>0.13$ and CP violating phase $\delta <45^o$. Moreover, the atmospheric mixing angle is close to the maximal value $45^o$. The neutrino less double beta decay...Go to contribution page

Dr Toshihiko Ota (Max-Planck-Institut fuer Kernphysik)28/07/2007, 14:40Flavor PhysicsParallel TalkWe discuss impact of non-standard interactions with neutrinos (NSIs) on future oscillation experiments. In order to study the sensitivity to NSIs, we perform the numerical simulations which take into account uncertainties in neutrino oscillation parameters, realistic experimental setups, and their systematic errors. We show that a neutrino factory experiment has excellent prospects of...Go to contribution page

Heinrich Paes (University of Alabama)28/07/2007, 15:00Flavor PhysicsParallel TalkTheories with large extra dimensions have provided new perspectives on a plethora of old problems in particle physics and cosmology. Interesting applications include the amelioration of the large hierarchy between the weak and the Planck scale, the generation of small neutrino masses and the prediction of quatum gravity effects at energy scales around a TeV. Also a non-inflationary...Go to contribution page

Mr Joachim Kopp (Max-Planck Institut fuer Kernphysik, Heidelberg)28/07/2007, 15:20Flavor PhysicsParallel TalkWe discuss the possibility to study oscillations of atmospheric neutrinos in the ATLAS experiment at CERN. Due to the large detector mass, a significant number of events is expected, and during the shutdown phases of the LHC, reconstruction of these events will be possible with very good energy and angular resolutions. We argue that 500 live days of neutrino running should be achievable,...Go to contribution page

Vladimir Vasiliev (University College London)28/07/2007, 15:40Flavor PhysicsParallel TalkThe NEMO-3 experiment located in the Modane Underground Laboratory (LSM) is searching for neutrinoless double beta decay. The experiment has been taking data since 2003 with a range of isotopes. The main isotopes are ~ 7 kg of 100Mo and ~ 1 kg of 82Se. Since no evidence for neutrinoless double beta decay has been found, a 90% Confidence Level lower limit on the half-life of this process...Go to contribution page
