Dear Colleagues, We are organising the special topics working group on Cosmological connections within the ALCPG Workshop in Snowmass (14-27 August). We are inviting you to contribute to this working group. Details on the Workshop and the general charge for the Physics Working groups can be found at https://alcpg2005.colorado.edu/alcpg2005/purpose/phys-charge. The topics that should be addressed by our working group are listed below. If you intend to contribute on one of these topics (or on another relevant topic for dark matter or cosmology that might have been omitted from this list) please contact us. Topics: A) Which measurements are important to make at colliders for accurate determination of relic density and/or cross-sections relevant for direct/indirect detection of dark matter? 1. Existence of SUSY and SUSY mass ranges and couplings from LHC/ILC 2. Existence of Xtra-Dim, measurements at LHC/ILC B) Dark matter in direct/indirect detection: LSP mass, couplings to nuclei, helo profile. Correlation between dark matter signals in direct/indirect detection and new physics at colliders (including the case of a positive signal in only one type of experiment). C) Dark matter candidates and possible tests at ILC: LSP in MSSM and beyond (CP violation, NMSSM ...), superwimps, Kaluza-Klein dark matter, Little Higgs models ...
