TitleNovel Approach to Fine-tuned Supersymmetric Standard Models, and the Explanation of the Muon Anomalous Magnetic Dipole Moment Anomal
SpeakerDr. Wen Yin (Tohoku Univ.)

I will propose an analyzing method for supersymmetric standard models with some amount of fine tuning. Applying this method to a non-universal Higgs masses model, I will show a new typical region and the explanation of the muon anomalous magnetic dipole moment (muon g-2) within its 1σ error. In particular, the explanation of the muon g-2 anomaly has been considered to be difficult in this model due to the heavy stop masses required by the measured SM Higgs boson mass and the condition of the universal sfermion mass at the GUT scale. [arXiv:1606.04953]

I will also propose a new simple set up of the MSSM, where at the GUT scale, only the Higgs sector is coupled with SUSY breaking. All the other sparticles obtain masses from the Higgs sector via RG running and superWeyl anomaly. The sfermion spectra are typical where the first two generation sfermions are as light as ~1TeV with anomaly induced gaugino masses, while the third ones, Higgsino and A-Higgs are heavier than O(10)TeV. I will discuss about the phenomenology of this set up, such as the explanation of the muon g-2 anomaly, the alleviation of gravitino/flavor problem and also other interesting possibilities.
