Gauge Invariance and k_T-Factorization of Exclusive Processes
F. Feng, J. P. Ma, Q. Wang
In the -factorization for exclusive processes, the nontrivial -dependence of perturbative coefficients, or hard parts, is obtained by taking off-shell partons. This bring…
Transverse-Momentum Dependent Factorization for gamma^* pi^0 to gamma
J. P. Ma, Q. Wang
With a consistent definition of transverse-momentum dependent (TMD) light-cone wave function, we show that the amplitude for the process can be factorized when the v…
On Two-Body Decays of A Scalar Glueball
K. T. Chao, X. G. He, J. P. Ma
We study two body decays of a scalar glueball. We show that in QCD a spin-0 pure glueball (a state only with gluons) cannot decay into a pair of light quarks if chiral symmetry hol…
Transverse Momentum Dependent Factorization for Radiative Leptonic Decay of B-Meson
J. P. Ma, Q. Wang
With a consistent definition of transverse-momentum-dependent(TMD) light-cone wave function of -meson, we show that the amplitude of the radiative leptonic B-decay can be factor…
