Leptogenesis in the type III seesaw mechanism
It is shown that the type III seesaw mechanism proposed recently can have certain advantages over the conventional (or type I) seesaw mechanism for leptogenesis. In particular a resonant enhancement of leptogenesis via heavy quasi-Dirac right-handed neutrino pairs can occur without a special flavor form or “texture” of the mass matrices being assumed. Some of the requirements for neutrino mixin...
متن کاملMinimal dark matter in type III seesaw
We explore the possibility of a new dark matter candidate in the supersymmetric type III seesaw mechanism where a neutral scalar component of the Y= 0 triplet can be the lightest supersymmetric particle. Its thermal abundance can be in the right range if non-standard cosmology such as kination domination is assumed. The enhanced cross-section of the dark matter annihilation to WW can leave dete...
متن کاملHiggs Boson Mass Bounds in the Standard Model with Type III and Type I Seesaw
In type III seesaw utilized to explain the observed solar and atmospheric neutrino oscillations the Standard Model (SM) particle spectrum is extended by introducing three SU(2)L triplet fermion fields. This can have important implications for the SM Higgs boson mass (MH) bounds based on vacuum stability and perturbativity arguments. We compute the appropriate renormalization group equations for...
متن کاملProbing seesaw at LHC
We have recently proposed a simple SU(5) theory with an adjoint fermionic multiplet on top of the usual minimal spectrum. This leads to the hybrid scenario of both type I and type III seesaw and it predicts the existence of the fermionic SU(2) triplet between 100 GeV and 1 TeV for a conventional GUT scale of about 1016 GeV, with main decays into W (Z) and leptons, correlated through Dirac Yukaw...
متن کاملOPTIMIZATION OF THE ee OPTION FOR THE ILC
The e−e− running mode is one of the interesting physics options at the International Linear Collider (ILC). The luminosity for e−e− collisions is reduced by the beam-beam effects. The resulting beamstrahlung energy loss and beambeam deflection angles as function of the vertical transverse offset are different compared to the ee collisions. In this paper, the dependence of these observables with...
