CP Violation in the Minimal Supersymmetric Seesaw Model / Ellis, John R. (CERN) ; Hisano, Junji (CERN ; KEK, Tsukuba) ; Lola, Smaragda (CERN) ; Raidal, Martti (CERN ; NICPB, Tallinn)
We study CP violation in the lepton sector of the supersymmetric extension of the Standard Model with three generations of massive singlet neutrinos with Yukawa couplings $Y_\nu$ to lepton doublets, in a minimal seesaw model for light neutrino masses and mixing. This model contains six physical CP-violating parameters, namely the phase $\delta$ observable in oscillations between light neutrino species, two Majorana phases $\phi_{1,2}$ that affect $\beta \beta_{0 \nu}$ decays, and three independent phases appearing in ${Y_\nu}{Y_\nu}^\dagger$, that control the rate of leptogenesis.

Leptogenesis and the violation of lepton number and CP at low energies / Ellis, Jonathan Richard (CERN) ; Raidal, Martti
In the context of the minimal supersymmetric seesaw model, we study the implications of the current neutrino data for thermal leptogenesis, $\beta\beta_{0\nu}$ decay, and leptonic flavour- and CP-violating low-energy observables. We express the heavy singlet-neutrino Dirac Yukawa couplings $(Y_\nu)_{ij}$ and Majorana masses $M_{N_i}$ in terms of the light-neutrino observables and an auxiliary hermitian matrix $H$, which enables us to scan systematically over the allowed parameter space.

Running of Low-Energy Neutrino Masses, Mixing Angles and CP Violation / Ellis, Jonathan Richard ; Hektor, A ; Kadastik, M ; Kannike, K ; Raidal, M
We calculate the running of low-energy neutrino parameters from the bottom up, parameterizing the unknown seesaw parameters in terms of the dominance matrix $R$. We find significant running only if the $R$ matrix is non-trivial and the light-neutrino masses are moderately degenerate. [...]

New parametrization of the seesaw mechanism and applications in supersymmetric models / Ellis, Jonathan Richard (CERN) ; Hisano, J ; Raidal, Martti ; Shimizu, Y
We present a new parametrization of the minimal seesaw model, expressing the heavy-singlet neutrino Dirac Yukawa couplings (Y/sub nu /)/sub ij/ and Majorana masses M(N/sub i/) in terms of effective light-neutrino observables and an auxiliary Hermitian matrix H. In the minimal supersymmetric version of the seesaw model, the latter can be related directly to other low-energy observables, including processes that violate charged lepton flavor and CP. [...]

Leptogenesis and low-energy CP violation in a type-II-dominated left-right seesaw model / Rink, Thomas (Heidelberg, Max Planck Inst.) ; Rodejohann, Werner (Heidelberg, Max Planck Inst.) ; Schmitz, Kai (CERN)
We consider leptogenesis in a left-right-symmetric seesaw scenario in which neutrino mass generation and leptogenesis are dominated by the type-II seesaw term. Motivated by grand unification, we assume that the neutrino Dirac mass matrix is dominated by a single entry of the order of the top-quark mass, which leaves the low-energy phases of the lepton mixing matrix as the only sources of CP violation.

Neutrino mass and leptogenesis / Yanagida, T (CERN)
We show that the seesaw mechanism may explain two independent physical parameters, small neutrino masses and universe's baryon- number asymmetry. The seesaw mechanism, thus, provides us with a big dream to relate the present baryon asymmetry to observables in neutrino physics. [...]

A possible relation between leptogenesis and PMNS phases / Covi, Laura (Gottingen U. ; CERN) ; Kim, Jihn E. (Pusan Natl. U.) ; Kyae, Bumseok (Pusan Natl. U. ; Korea Inst. Advanced Study, Seoul) ; Nam, Soonkeon (Kyung Hee U.)
The CP phase relevant in the leptogenesis is related to the PMNS phase in case only one CP phase appears in the full theory. Thus, the CP phase is introduced by spontaneous CP violation at a high energy scale toward realizing the successful Kobayashi-Maskawa electroweak CP violation. [...]
