Could you have BOTH mirror matter and supersymmetry?

  1. May 23, 2009 #1
    I know that mirror symmetry resulting in mirror matter and supersymmetry resulting in SUSY partners are two completely distinct fields, and that the original bosonic string theory needs SUSY to get fermions.

    If mirror matter does exist in the universe, what would this mean in terms of SUSY? Would we have a multiplication of dark matter candidates?

    I suggested that because I really don't know anything about mirror matter... so, maybe by looking at some references, we could find something.

    fair enough :)

    I found something:

    It seems that anti generation is a mirror generation.

    Mediation of Supersymmetry Breaking via Anti-Generation Fields

    Authors: M.Ito (Nagoya Univ), T.Matsuoka (Koggakan Univ)
    (Submitted on 31 Jan 2000 (v1), last revised 13 May 2000 (this version, v3))

    Abstract: In the context of the weakly coupled heterotic string, we propose a new model of mediating supersymmetry breaking. The breakdown of supersymmetry in the hidden sector is transmitted to anti-generation fields via gravitational interactions. Subsequent transmission of the breaking to the MSSM sector occurs via gauge interactions. It is shown that the mass spectra of superparticles are phenomenologically viable.

    It seems Takeo Matsuoka has several papers regarding your question:

    I guess this is also very helpful:

    Mirror particles and mirror matter: 50 years of speculation and search
    Authors: L.B. Okun
    (Submitted on 19 Jun 2006 (v1), last revised 1 Dec 2006 (this version, v2))

    Abstract: This review describes the history of discovery of violation of spatial parity P, charge conjugation parity C, combined parity CP. The hypothesis of existence of mirror particles was called upon by its authors to restore the symmetry between left and right. The review presents the emergence and evolution of the concepts ``mirror particles'' and ``mirror matter''. It could serve as a concise guide to the ``mirror-land''. An important part of the review is the list of about 250 references with their titles.

    At the end of the above article, the author gives a warning when searching for mirror matter (p.11, conclusions):

    "The extra articles in Google Scholar do not deal with those mirror particles that are the subject of this review. They are “mirror” in a different sense. For instance, the terms “mirror families” or “mirror fermions” refer to hypothetical families of very heavy fermions with reversed isotopic quantum numbers, which are presumed to interact with ordinary photons and gluons."

    I guess it is in this sense that Matsuoka treats mirror particles. So, I guess the mirror family that is contained in garrett lisi is not related to the question of electroweak break.
