Study of Three-Body Y(10860) Decays

I. Adachi, K. Adamczyk, H. Aihara +337

We report preliminary results on the analysis of the three-body Y(10860)=> B barB pi, Y(10860) => (B barB* + c.c.) pi and Y(10860)=> B* barB* pi decays including an observation of…

Evidence for a Zb0(10610) in Dalitz analysis of Y(5S) -> Y(nS) pi0 pi0

I. Adachi, K. Adamczyk, H. Aihara +331

We report the first observation of Y(5S) -> Y(1,2S) pi0 pi0 decays. Evidence for the Zb0(10610) with 4.9sigma significance is found in a Dalitz plot analysis of Y(5S) -> Y(2S) pi0…

Threshold Effects in the Decay of Heavy b' and t' Quarks

Yuan Chao, Kai-Feng Chen, Shing-Kuo Chen +3

A sequential fourth generation is still viable, but the t' and b' quarks are constrained to be not too far apart in mass. The t'{\to}bW and b'{\to}tW decay channels are still being…

Belle II Technical Design Report

T. Abe, I. Adachi, K. Adamczyk +407

The Belle detector at the KEKB electron-positron collider has collected almost 1 billion Y(4S) events in its decade of operation. Super-KEKB, an upgrade of KEKB is under constructi…

Measurement of the Differential Branching Fraction and Forward-Backword Asymmetry for B->K(*)l+l-

J. -T. Wei, P. Chang

We study B->K(*)l+l- decays (l=e,mu) based on a data sample of 657 million BB pairs collected with the Belle detector at the KEKB e+e- collider. We report the differential branchin…

Heavy b' and t' Decay

Yuan Chao, Kai-Feng Chen, Shing-Kuo Chen +3

Heavy is currently being searched for at the Tevatron, but a broader spectrum should be explored at the LHC. For , we discuss the two decay branches, $…
