This paper gives results for the spectrum, all allowed E1 radiative partial widths (and some important M1 widths) and all open-charm strong decay amplitudes of all 40 c-cbar states expected up to the mass of the 4S multiplet, just above 4.4 GeV. The spectrum and radiative widths are evaluated using two models, the relativized Godfrey-Isgur model and a nonrelativistic potential model. The electromagnetic transitions are evaluated using Coulomb plus linear plus smeared hyperfine wavefunctions, both in a nonrelativistic potential model and in the Godfrey-Isgur model. The open-flavor strong decay amplitudes are determined assuming harmonic oscillator wavefunctions and the 3P0 decay model. This work is intended to motivate future experimental studies of higher-mass charmonia, and may be useful for the analysis of high-statistics data sets to be accumulated by the BES, CLEO and GSI facilities.

A tale of Bethe logarithms: leptonic widths of $\chi_{cJ}$ and Lamb shift
The infrared divergence in chi_cJ to e+e- decays is canceled by adding the next-to-leading Fock component, yielding finite, scale-independent leptonic width predictions expressed through Bethe logarithms.

Toponia at the HL-LHC and FCC-ee
Toponium ηt and ψt states have promising discovery channels at HL-LHC (ηt b bbar, about 6σ) and FCC-ee (ψt interference in b bbar, about 14σ), while P-wave states remain out of reach.

Fully charmed P-wave tetraquark resonant states in the quark model
A quark-model calculation predicts compact fully charmed P-wave tetraquark resonances near 7.0 to 7.2 GeV, including exotic J^PC = 0^-- and 1^-+ states, and finds no narrow tetraquark candidates below 7 GeV for X(6400...

Vector charmonium(-like) states in the energy range of 4.1-4.6 GeV
A coupled-channel framework is developed and fitted to BESIII data on vector charmonium-like states in the 4.1-4.6 GeV range, concluding that coupled-channel effects with dynamically generated poles explain the line shapes.

Radiative Decays of Vector Mesons with Light-Cone Sum Rules
Light-cone sum rules yield radiative decay widths for ground-state vector mesons that match data where available and exhibit a universal linear dependence on a function A(x) in log coordinates arising from decay-const...

Systematic study of light and charm meson M1 radiative transitions
The paper calculates vector meson magnetic moments and M1 radiative decay widths for light and charm mesons, finding that both models need empirical scale factors to match measured charm decays.
