Title of the Seminar: "First Measurements of the
Exclusive Decays of Y(5S) to B(*)B(*)(pi)(pi) Final
States and Improved Bs* Mass Measurement"


 Abstract:
 Using 420 pb-1 of data collected on the Y(5S)
 resonance in CLEO,  we exploit exclusive
 reconstruction of B mesons in 25 channels to
 measure or set upper limits on the decay of the Y(5S)
 into B(*)B(*)(pi)(pi) final states for the first time
 in the world.  We also extract the most precise value
 of the Bs* mass to date.
 An introduction to the BTeV RICH will also be
 presented, which leads to BeamTest results we got in
 Fermi Lab.
