Last update: 09/12/2000, J. Wilkes

This website resulted from a discussion at the Neutrinos with Mass workshop, at the Aspen Center for Physics in July, 2000 (see list of participants). Its aim is to provide a forum for ideas, calculations, and presentation materials by people interested in neutrino factories and long-baseline experiments, in preparation for the Snowmass meeting in Summer, 2001. Please tell anyone you know who may be interested in the subject about this website!

• Prior to our Aspen workshop, several related meetings and workshops took place:
• NNN99, in September, 1999 at Stony Brook
• MuMu99, in December, 1999 at San Francisco
• NuFact00, in May, 2000 at Monterey
• NuFact/MuMu Collaboration Meeting, May, 2000 at Catalina.

The table below was constructed by participants at Aspen, and is by no means authoritative. Official representatives of experiments mentioned are encouraged to complain and supply corrected figures where appropriate! Send corrections to Jeff Wilkes.

The following assumes dm²₂₃ = 3 x 10^-3 eV² and sin²2q_mt = 1.0.

Table entries represent the capability (yes/no or resolution) for each oscillation property listed.

X=No, =Yes, ?=official reps invited to please tell us!
