Observation of a narrow charmonium-like state in exclusive B+ -> K+ pi+pi- J/psi decays

The Belle Collaboration, S. -K. Choi, S. L. Olsen

We report the observation of a narrow charmonium-like state produced in the exclusive decay process B+ -> K+ pi+pi- J/psi. This state, which decays into pi+pi- J/psi, has a mass of…

Observation of B→K∗ℓ+ℓ−

A. Ishikawa

We report the first observation of the flavor-changing neutral current decay B→K∗ℓ+ℓ− and an improved measurement of the decay B→Kℓ+ℓ−, where $\ell…

Observation of B+→χc0​K+

K. Abe, The Belle Collaboration

We report the first observation of the decay B+→χc0​K+ using 21.3 fb−1 of data collected by the Belle detector at the Υ(4S) resonance. The preliminary result for…
