Constraints on lepton flavour violation and leptogenesis
Martti Raidal
We consider the scenario of direct leptogenesis from the decays of heavy sneutrino which also plays a role of inflaton. We calculate its predictions for flavour-violating decays of…
Tests of the left-right electroweak model at linear collider
K. Huitu, J. Maalampi, P. N. Pandita +3
The left-right model is a gauge theory of electroweak interactions based on the gauge symmetry SU(2)_R . The main motivations for this model are that it gives an explanation for th…
Lepton Number and Lepton Flavour Violation in Left-Right Symmetric Models
Martti Raidal
The sources of lepton flavour and lepton number violation in the left-right symmetric models are reviewed and the most sensitive processes to these violations are discussed. Both t…
μ-e Conversion Versus μ-->e γ
Martti Raidal
We compare two most relevant loop induced muon number violating processes, μ--> e γand μ-e conversion in nuclei, in constraining new physics. Because of much richer structure of th…
Bileptons - Present Constraints and Future Prospects at Colliders
Martti Raidal
Bosons which couple to two leptons and carry lepton number L=2, generically called bileptons, appear in many extensions of the standard model. We review the present constraints on…
Single W-boson production in e-γcolliders
K. Huitu, J. Maalampi, M. Raidal
Single -boson production in collisions with polarized beams is investigated. In the framework of the Standard Model the updated estimates for the measurement precision of…
