A study of the Kπ system

An angular analysis of Bd->J/ψKπ was performed in bins of Kπ mass. It was decided to neglect background. Angular acceptance maybe not very accurate (MC10, interpolated parameters, etc.) but is hoped to be good enough to identify the dominant wave in each bin. Clear evidence of spin 2, favouring K...

description An angular analysis of Bd->J/ψKπ was performed in bins of Kπ mass. It was decided to neglect background. Angular acceptance maybe not very accurate (MC10, interpolated parameters, etc.) but is hoped to be good enough to identify the dominant wave in each bin. Clear evidence of spin 2, favouring K*2(1430) instead of K*0(1430) was found. S-wave seems to be the main amplitude in (1000-1300 MeV), but small variation in phases causes big changes in wave shapes, probably interferences play a dominant role in that region.
