Physics Topics – Overview
Testing the Standard Model
CKM Matrix elements
Tests of Theoretical Models necessary to interpret critical CKM data
Tests of theories used to interpret B decay data
Beyond SM possibilities
Mixing
CPV
Rare Decays
Engineering measurements: e. g. absolute B's
Unique Opportunities at Charm Thresholds
Unique event properties
Only DD not DDx produced
Can get DoDo, D+D-, DsDs , LcLc
Probably other charmed baryons as well (not yet measured)
Large cross sections
s(DoDo) = 5.8 nb
s(D+D-) = 4.2 nb
s(Ds Ds) = 0.5 nb
R (units of s(m+m-))

s(m+m-)= 5.4 nb at 4 GeV
Kinematical Niceties
Ease of B measurements using "double tags"
BA = # of A/# of D's
