Reconciling the nonrelativistic QCD prediction and the $J / ψ \to 3 γ$ data

Feng Feng, Yu Jia, Wen-Long Sang

It has been a long-standing problem that the rare electromagnetic decay process $J / ψ \to 3 γ$ is plagued with both large and negative radiative and relativistic corrections. To date…

Relativistic corrections to the axial vector and vector currents in the bar{b}c meson system at order alpha_s

Jungil Lee, WenLong Sang, Seyong Kim

We compute the short distance coefficients for the NRQCD factorization formulas of the meson-to-vacuum matrix elements for the axial vector and vector parts of the charged weak cur…

Observation prospects of leptonic and Dalitz decays of pseudoscalar quarkonia

Yu Jia, Wen-Long Sang

Two types of pseudoscalar quarkonium electromagnetic decay processes, i.e. decay to a lepton pair, and to a lepton pair plus a photon (Dalitz decay), are analyzed at the leading or…
