J/ψ → DP, DV decays in the QCD factorization approach

Abstract

Motivated by the recent measurements on nonleptonic J/ψ weak decays at BESIII and the potential prospects of J/ψ meson at the high-luminosity heavy-flavor experiments, the branching ratios of the two-body nonleptonic J/ψ → DP , DV decays are estimated quantitatively by considering the QCD radiative corrections to hadronic matrix elements with the QCD factorization approach. It is found that the Cabibbo favoreddecays have branching ratios > ∼ 10 −10 , which might be promisingly detectable in the near future.

“…Nonfactorizable effects from HME are considered with the QCDF scheme in Ref. [24] and with the pQCD approach in this paper. By and large, branching ratio for a given J/ψ → D s,d P decay has the same order of magnitude with different phenomenological models.…”

“…Recently, many QCD-inspired methods have been developed, such as the pQCD approach [8][9][10], the QCD factorization (QCDF) approach [14][15][16], the soft and collinear effective theory [17][18][19][20], and have been applied preferably to accommodate measurements on nonleptonic B decays. Based on collinear approximation, the J/ψ → DP decays have been studied with naive factorization [21][22][23] and the QCDF approach [24], where theoretical results differ mainly from hadronic input parameters. In this paper, the J/ψ → D s,d P decays will be studied with the pQCD approach based on k T factorization.…”

Study of $J/ψ$ ${\to}$ $D_{s,d}V$ decays with perturbative QCD approach

“…In recent years, some QCDinspired methods, such as pQCD approach [10][11][12], QCD factorization approach [16][17][18], soft and collinear effective theory [19][20][21][22], have been fully formulated to explain nonleptonic B decays. The J/ψ → D q V decays have been investigated based on collinear approximation [23][24][25][26]. In this paper, the J/ψ → D s,d V decays will be restudied based on k T factorization.…”
