We study the phenomenology of
Dirac fermion 5-plets leading to the tree-level seesaw different from
standard type I and III. They give rise to the seesaw formula m_{nu} ~ v^6/M^5
which reproduces masses for light neutrinos m_{nu} ~ 10^{-1} eV by M > TeV new states, testable at the LHC.
Their Drell-Yan production rates are enhanced due to the
enlarged effective gauge couplings, and...

An exciting prospect for LHC physics is the lepton number violating signals associated with Majoarana neutrino mass generation. Such signals crucially depend on the nature of the associated seesaw fields and could be absent (even for fields with LHC-friendly masses) if these fields cannot be easily produced. A startling exception is the recently proposed colorful seesaw where the color...

In type-III seesaw the generation of a lepton asymmetry proceeds via the dynamics of Majorana electroweak triplets. In this talk I will discuss the importance of flavor effects in this type of models, in particular the impact that such effects can have for TeV-scale triplets. I will show that as long as the asymmetry is produced by the
dynamics of the lightest triplet flavor effects are...
