Diffractive dissociation reactions at COMPASS provide clean access to mesons with masses below ≈ 2.5 GeV /c2. This paper presents a partial wave analysis of about 420 000 π- Pb → π-π-π+ Pb events at 190 GeV/c beam momentum and with four-momentum transfer t' ∈ [0.1,1] GeV 2/c2. The well-known a1(1260), a2(1320) and π2(1670) mesons are resolved with high quality. Also the less established states π(1800) and a4(2040) are seen. In addition, a resonance in the spin-exotic JPC = 1-+ wave is observed. A mass-dependent fit results in a mass and width of [Formula: see text] and [Formula: see text], respectively, which is consistent with the disputed hybrid candidate π1(1600).

Ionic Effects

Partial wave analysis together with the qualitative examination of hybridization has been performed for two ordered intermetallic alloys with CsCl structure, FeV, and CoTi. The results resemble those obtained previously for FeTi, although important deviations are present as well. The stabilization of the ordered phase is again due to ionic effects. Qualitative arguments are suggested to explain the small stability of the CsCl phase of FeV and some differences in the FeTi and CoTi phase diagrams.
