Study of radiative bottomonium transitions using converted photons
Study of radiative bottomonium transitions using converted photons
We use (111±1) million Υ(3S) and (89±1) million Υ(2S) events recorded by the BABAR detector at the PEP-II B-factory at SLAC to perform a study of radiative transitions between bottomonium states using photons that have been converted to e+e− pairs by the detector material. We observe Υ(3S)→γχb0,2(1P) decay, make precise …
