Subject line: Invitation to support a future linear e+e- collider Dear colleague, As part of the work of the Worldwide Study of Physics and Detectors for a Future Linear Collider a document supporting the linear collider programme has been written*: "Understanding Matter, Energy, Space and Time : The Case for the e+e- Linear Collider". It sets out the scientific case for a 500 GeV e+e- linear collider, upgradable to higher energy in future and with options retained for special investigations with alternate beam particles and added polarization capability. Our goals for this document are to: 1. Give the first coordinated statement of the case for the Linear collider by physicists in all regions of the world, and outline the nature of the detector requirements. 2. Provide an outline of the scientific goals that is accessible to scientists in related fields. 3. Provide the background for how future evolution of our physics understanding will shape the need for optional added features; this information is needed for the international planning to set the linear collider parameters and baseline scope. 4. Describe the place of the linear collider program in relation to the LHC research, and in the larger context of other major thrusts within high energy physics. The document notes that two technical proposals for realizing a linear collider now exist, but makes no judgement on which might be chosen. It was first circulated in October 2002 and has been publicly debated at open meetings during Linear Collider Workshops at Prague in November and at Arlington Texas in January. Inputs from those meetings and by email have been incorporated in the final version of the document, which can be found at: http://sbhep1.physics.sunysb.edu/~grannis/wwlc_report.html We are preparing a list of those who support the Linear Collider project and the pursuit of the scientific goals outlined in the document. This list, to be made available on the International LC web page, will serve as a demonstration of the widespread support in the community for the linear collider project. Those on the mailing list of the Asian, European or North American linear collider working groups should already have been contacted to ask for permission to include them as signatories. We welcome the signatures of any particle phsyicists who wish to give their support. If you are not now on one of the regional LC mailing lists you may join the supporter's list by accessing the following interactive website: http://www-flc.desy.de/lcsurvey/. If you wish to, lease try and add you name before March 7. That is not a hard cutoff, but we would like to go public soon after that. Many thanks Yours sincerely David Miller Chair of the ECFA/DESY Study on Physics and Detectors for a Linear Collider; co-chair of the Worldwide Study. ___________________________________________________ * Drafting panel; Paul Grannis (Stony Brook, USA), Francois Richard (Orsay, France), Takayuki Matsui (KEK, Japan), Sachio Komamiya (Tokyo, Japan). -- ******************************************************************** * Prof. David J.
