Workshop Program and Agenda

The format will be topical sessions with a program of invited and contributed talks. All talks are short, with the intention to have coverage of a large number of topics. The program agenda will leave time for some questions and discussions after each talk, with extra discussion time at the conclusion of each session. The workshop format is intended to provide for an active discussion in these periods among all participants.

Here is the LRT2004 agenda of talks. Posters are also invited and will be posted in the lunch and coffee break hall for lunch time and inter-session discussions.

The following is the final workshop program, click on the link for each talk to download the ppt or pdf file. Please email lrt2004@snolab.ca if any links are incorrect.
