[String-schools] [theory-conf-contacts] LHC Inverse WorkshopAnnouncement

    Hi,

    something for the more pheno based people among us...

    Cheers,

    Gabi

    Dear Colleague,

    With the imminent start of the LHC in 2007 particle physics is on the
    threshold of its most exciting period in over three decades. The
    physics of the TeV scale will begin to be uncovered, and whatever is
    found will have profound implications for fundamental physics. Over the
    past two decades many models of weak scale physics have been proposed.
    It is clear that the era of poorly-constrained speculation and
    model-building is nearing an end. It is unlikely that building more
    models exploring variations on the mechanism for electroweak symmetry
    breaking is particularly important now, unless some qualitatively new
    ideas and associated signals are involved.

    Instead, there is another problem, far more urgent especially as the LHC
    draws near, that has received less attention. How will we unambiguously
    determine the underlying new physics from LHC data, once the existence
    of a signal is established? Suppose we become confident supersymmetry
    has been discovered - can we determine even qualitative features of the
    spectrum? Can we, for instance, tell even roughly whether or not the
    gaugino masses are consistent with unification at the scale where the
    gauge couplings unify? Whether the LSP can account for the dark matter?


    Little systematic work has been done on this "inverse problem". Most
    collider phenomenology has been done in the "forward" direction, from
    the parameter space to the signatures. Often the signals are from very
    special models, chosen to have far fewer parameters than the general
    theory. Such studies were appropriate, with the hope that we would gain
    familiarity with the associated signals and be able to recognize them if
    they arise at LHC.

    But the LHC inverse problem is much more interesting and important. We
    can split it into 3 categories:

    LHC-1A - What is the new physics?

    LHC-1B - What is the spectrum and effective Lagrangian of the new
    physics at the weak scale?

    LHC-1C - How can we begin to study what the underlying theory is,
    perhaps at a high scale and/or in extra dimensions?

    We think it is important to make progress with the LHC-1 problem now,
    rather than waiting. To help do that we plan to have a series of
    Harvard-Michigan meetings on the LHC-1 problem. The first will be at
    the University of Michigan, organized by the Michigan Center for
    Theoretical Physics, April 12-15, 2006. Everyone is welcome to attend.
    Please let us know if you are interested in reporting on some relevant
    research. We plan to focus narrowly, so we expect to only schedule
    talks relevant to data likely to be available in the next few years.

    By late-January a web site will be up, on the MCTP site
    (www.umich.edu/~mctp/), from which participants can register, arrange
    accommodations, and obtain travel information. A limited amount of
    funds will be available to support some participants. Please share this
    message with any interested people.
