Dear Colleague, We are writing to call your attention to the DPF parallel session on Physics at Lepton Colliders. This session is intended to cover both theoretical and experimental developments in areas of physics that can be addressed by future lepton colliders, including both those at the energy and luminosity frontiers. We encourage anyone with recent results in this area to submit an abstract and to join our sessions at Brown University in August. Note that the deadline for submission of abstracts has been extended to Monday, May 23. Abstracts that appear after that date may be considered, as appropriate. You may submit an abstract by clicking on the following link and logging on with your INDICO account. Should you have trouble doing this, you may also submit an abstract directly to Bruce Schumm at [log in to unmask] The URL for general information about the Aug 9-13 DPF meeting is http://www.hep.brown.edu/~DPF2011/. Best, The Physics at Lepton Colliders conveners, who are Estia Eichten [log in to unmask] JoAnne Hewett [log in to unmask] Bruce Schumm [log in to unmask]
