Production of single P-wave ccbar and bbbar states

In this talk I will discuss the production of the singlet P-wave bbbar and ccbar ^1P_1 states, h_b and h_c. We consider two possibilities. In the first the ^1P_1 state are produced via electromagentic cascades; n^3S_1 -> n'^1S_0 + gamma -> 1^P_1 + gamma gamma. A more promising approach consiste of single pion transition to the ^1P_1 state followed by the radiative transition to the 1^1S_0 state. For a million Upsilon(3S) or psi' 's produced we expect these processes to produce several hundred events.
