*A novel type of proximity focusing RICH counter with multiple refractive index aerogel radiator Reviewed Open Access

T.Iijima, S.Korpar et al.

Nucl. Instr. and Meth. A Vol. 548 page： 383-390 2005.6

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

A novel type of ring imaging Cherenkov detectors, with radiator consisting of two or more aerogel layers of different refractive indices, has been introduced for the first time and tested with beams. We have shown that the new technique allows us to increase the number of detected photons by 40% without deterirating the angular resolution.

Spectra of prompt electrons from decays of $B^+$ and $B^0$ mesons and ratio of inclusive semielectronic branching fractions Reviewed Open Access

T.Okabe et al. (The Belle Collaboration)

Phys. Lett. B Vol. 614 page： 27 2005.4

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

We have measured the spectra of prompt electrons from decays of the neutral and charged B mesons using the data collected at the KEK B factory. We have determined the partial rate of semileptonic decay for the momentum region greater than 0.6GeV/c, from which the Cabibbo-Kobayashi-Masakawa matrix element |Vcb| can be deduced.
