چکیده
In the f2(1270)−f ′ 2(1525) mixing framework, the isoscalar singlet-octet mixing angle for 1 P2 tensor nonet is determined to the value of 27.5◦ and the decays of the two states are investigated. Comparing the predicted results of the decays of the two states with the available experimental data, we find that the predicted results are in good agreement with the experimental data, which shows that the f2(1270) and f ′ 2(1525) wave functions don’t need other components such as glueballs or the 2 P2, 3 P2, ... qq. ∗E-mail: [email protected]/[email protected] †Mailing address 1

متن کاملHard Exclusive Production of Tensor Mesons
We point out that hard exclusive production of tensor mesons f 2 (1270) with helicity λ = ±2 is dominated by the gluon component in the meson wave function and can be used to determine gluon admixture in tensor mesons in a theoretically clean manner. We present a detailed analysis of the tensor meson distribution amplitudes and calculate the transition form factor γ + γ * → f 2 (1270) for one r...
متن کاملK ∗ 0 ( 892 ) K̄ ∗ 02 ( 1430 ) decays
We present an approach to study the decay modes of the J/ψ into a vector meson and a tensor meson, taking into account the nature of the f2(1270), f ′ 2(1525), K̄∗ 0 2 (1430) resonances as dynamically generated states from the vector meson-vector meson interaction. We evaluate four ratios of partial decay widths in terms of a flavor dependent OZI breaking parameter and the results obtained compa...
متن کاملΛ ( 1520 ) production in Z decays
Preliminary DELPHI results from two analyses are presented: 1. Λ(1520) production in Z0→qq, 2. Inclusive ρ, f0(980), f2(1270), K ∗0 2 (1430) and f ′ 2(1525) production in Z 0→ qq. Both analyses are based on about 2 million multihadronic events collected in 1994 and 1995, using the particle identification capabilities of the DELPHI Ring Imaging Cherenkov detectors and measured ionisation losses ...
متن کاملTwo-photon partial widths of tensor mesons
We calculate partial widths of the γγ decay of the tensor qq̄ states a2(1320), f2(1270), f2(1525), their radial excitations a2(1660), f2(1640), f2(1800) as well as F2qq̄ states. Calculations are performed in the framework of the same approach which was used before for the study of radiative decays f0(980) → γγ, a0(980) → γγ and φ(1020) → γf0(980): the assumption made is that of qq̄ structure of f0...
