42. Heavy Fermions and some Aspects of Physics Beyond the SM

We emphasize the role of Heavy Fermions in various aspects of fundamental physics such as: i) Generating all CP violations from a vaccum phase. ii) Generating Naturally Suppressed Deviations of 3x3 Unitarity and Flavour-Changing Neutral Currents. iii) Providing a Possible Solution to the Strong CP problem. iv ) Impact on CP Asymmetries

We construct extensions of the Standard Model with two Higgs doublets, where there are flavour changing neutral currents both in the quark and leptonic sectors, with their strength fixed by the fermion mixing matrices $V_{CKM}$ and $V_{PMNS}$. These models are an extension to the leptonic sector of the class of models previously considered by Branco, Grimus and Lavoura, for the quark sector....

35. Left Right symmetry, neutrinoless double beta decay and the LHC

The question of parity restoration has lead to a theory with a left-right symmetric gauge sector, which predicts a non-zero neutrino mass. The existence of (heavy) right-handed neutrinos leads to lepton number violating phenomena at low and high energy scales in the form of neutrinoless double beta decay and two leptons with two jet signatures at colliders. We argue that the neutrinoless...

47. Low scale Left-Right symmetry: phenomenology and first bounds from LHC

Dr Fabrizio Nesti

Low scale restoration of Left-Right symmetry is reviewed, with emphasis of the possibility of its striking detection at LHC up to 4 TeV thanks to low scale Lepton-Number-Violation, which may turn out to be required by the claimed evidence and the future studies of neutrinoless double-beta decay, clashing with tightening constraints from cosmology. I focus on the minimal SU(2)L × SU(2)R ×...
