Infinite possibilities

  • H. Murayama
  • Many of these extensions

were proposed to address some unsolved questions

  • f the SM: hierarchy

problem, generation and flavour problem

  • Others simply to explain

some deviations of the SM, top forward backward asymmetry, μ→eγ, h→γγ, non universal lepton decays, DM, etc…

Evidence of Physics BSM

LHC put constraints only in PBSM Neutrino masses * (In the SM L is not violated) Cosmology: Dark Matter, Baryon Asymmetry, Dark Energy … Some theoretical aspects like hierarchy problem something else? LHC? rare decays …

If we impose Lepton number then the neutrinos are Dirac particles just like quarks and charged leptons many orders of magnitude

Neutrino masses from higher dim Higgses

Aranda, EP (2015)

Imposing the condition rho parameter 1 at tree level
 
 
 the minimal is a septet with Y=2 What do we need for this to contribute to Neutrino masses? What are the conditions?

In order to preserve the tree level rho parameter we must impose a Z2 symmetry, in such a way the neutral components of the scalar fields remain vevless Z2

Conclusions

We have evidence of “physics beyond the SM” It is interesting to find scenarios where some of them have a common explanation neutrino physics is a nice “portal to PBSM” DM stability and neutrino physics can be related Neutrino and BAU also related why not neutrinos - DM - BAU
