Implications of spin symmetry for XYZ states
Q. Wang, V. Baru, E. Epelbaum +4
Numerous exotic candidates containing a heavy quark and anti-quark (the so-called states) have been reported since the observation of the in 2003. For these systems…
The line shapes of the and in the elastic and inelastic channels revisited
Q. Wang, V. Baru, A. A. Filin +3
The most recent experimental data for all measured production and decay channels of the bottomonium-like states and are analysed simultaneously using solu…
Interplay of quark and meson degrees of freedom in near-threshold states: A practical parametrisation for line shapes
F. -K. Guo, C. Hanhart, Yu. S. Kalashnikova +5
We propose a practical parametrisation for the line shapes of near-threshold states compatible with all requirements of unitarity and analyticity. The coupled-channel system underl…
QCD Evolutions of Twist-3 Chirality-Odd Operators
J. P. Ma, Q. Wang, G. P. Zhang
We study the scale dependence of twist-3 distributions defined with chirality-odd quark-gluon operators. To derive the scale dependence we explicitly calculate these distributions…
Scale Dependence of Twist-3 Quark-Gluon Operators for Single Spin Asymmetries
J. P. Ma, Q. Wang
We derive the scale dependence of twist-3 quark-gluon operators, or ETQS matrix elements, at one-loop. These operators are used to factorize transverse single spin asymmetries, whi…
A Note on the -Factorization for Exclusive Processes
F. Feng, J. P. Ma, Q. Wang
We show in detail that the -factorization for exclusive processes is gauge-dependent and inconsistent.
