Light-cone distribution amplitudes of light J(PC)=2(--) tensor mesons in QCD

2018-06-01
We present a study for two-quark light-cone distribution amplitudes for the 1(3) D-2 light tensor meson states with quantum number J(PC) = 2(--). Because of the G-parity, the chiral-even two-quark light-cone distribution amplitudes of this tensor meson are antisymmetric under the interchange of momentum fractions of the quark and antiquark in the SU(3) limit, while the chiral-odd ones are symmetric. The asymptotic leading-twist LCDAs with the strange quark mass correction are shown. We estimate the relevant parameters, the decay constants fT and f1/T, and first Gegenbauer moment a1/T, by using the QCD sum rule method. These parameters play a central role in the investigation of B meson decaying into the 2(--) tensor mesons. (c) 2018 The Authors. Published by Elsevier B.V.
