“…We calculated the K 1 strong decays using both the flux-tube breaking model and the 3 P 0 model for several sets of wavefunctions. In all cases we fitted γ to 28 of the best known meson decays by minimizing the χ 2 defined by χ 2 = i (Γ theory i − Γ exp i ) 2 /δΓ 2 i where δΓ i is the experimental error 4 . The details of these fits are given in Ref.…”

“…Recently, the TPC/Two-Gamma Collaboration has presented measurements for the decays τ − → ν τ K − 1 (1270) and τ − → ν τ K − 1 (1400) [4]. It is expected that the LEP, CLEO, and BES collaborations, with their large samples of τ 's, will be able to study these decays in further detail [5].…”

“…In the figure for R both curves lie on each other. The solid and dotted lines are for the experimental values and their 1 − σ errors from the TPC/Two-Gamma measurement[4]. In addition, in the figure for BR(τ → νK 1 ), the solid line bounded by the dot-dot-dashed lines are for the CLEO/ALEPH result and their 1 − σ error[19].…”

We studied properties of the strange axial mesons in the relativized quark model. We calculated the K 1 decay constant in the quark model and showed how it can be used to extract theis the most sensitive measurement and also the most reliable since the largest of the theoretical uncertainties factor out. However the current bounds extracted from the TPC/Two-Gamma collaboration measurements are rather weak: we typically obtain −30 o < ∼ θ K < ∼ 50 o at 68% C.L. We also calculated the strong OZI-allowed decays in the pseudoscalar emission model and the flux-tube breaking model and extracted a 3 P 1 − 1 P 1 mixing angle of θ K ≃ 45 o . Our analysis also indicates that the heavy quark limit does not give a good description of the strange mesons.

“…To extract θ K from the weak decay constants we consider the measurements of the TPC/2γ collaboration [18] BR(τ → νK 1 (1270)) = (0.41 +.41 −.35 ) × 10 −2 BR(τ → νK 1 (1400)) = (0.76 +.40 −.33 ) × 10 −2 BR(τ → νK 1 ) = (1.17 +.41 −.37 ) × 10 −2 . We use the ratio…”
