Odd and even partial waves of ??- and ??- in ?-p ->?()?-p at 191GeV/c
Original language description
Exclusive production of ??- and ??- has been studied with a 191 GeV/c ?- beam impinging on a hydrogen target at COMPASS (CERN). Partial-wave analyses reveal different odd/even angular momentum (L) characteristics in the inspected invariant mass range upto 3 GeV/c2. A striking similarity between the two systems is observed for the L = 2, 4, 6 intensities (scaled by kinematical factors) and the relative phases. The known resonances a2(1320) and a4(2040) are in line with this similarity. In contrast, a strong enhancement of ??- over ??- is found for the L = 1, 3, 5 waves, which carry non-qq quantum numbers. The L = 1 intensity peaks at 1.7 GeV/c2 in ??- and at 1.4 GeV/c2 in ??-, the corresponding phase motions with respect to L =2 are different.
