Radiative transition decay width of $ψ_{2} (3823) \to γ χ_{c 1}$ from lattice QCD

Ning Li, Yan Gao, Feiyu Chen +4

We present an exploratory $N_{f} = 2$ lattice QCD study of $ψ_{2} (3823) \to γ χ_{c 1}$ at a pion mass $m_{π} \approx 350$ ~MeV. The related two-point and three-piont functions are calculated us…

Decays of $1^{-+}$ Charmoniumlike Hybrid

Chunjiang Shi, Ying Chen, Ming Gong +3

By extracting the transition amplitudes, we give the first lattice QCD prediction of the two-body decay partial widths of the $1^{-+}$ charmoniumlike hybrid $η_{c 1}$ . Given the cal…

Scale invariant curvature perturbations from a spontaneously decaying scalar field

Richard Lieu, Chun-Hui Shi

The evolution of superhorizon curvature perturbations in a two-component interacting universe is considered. It is found that adiabatic modes conserve the total curvature perturbat…
