  title={Electroweak production of \$\chi\_\{Q1\}\$ states in \$e^+e^-\$ collisions: A brief review},
  author={Nikolai N. Achasov and A. V. Kiselev and G. N. Shestakov},
A brief review of the available experimental and theoretical results on the production of the χ Q 1 states in e + e − annihilation and photon-photon γγ ∗ interactions is presented. Future data on the production of the χ c 1 (1 P ), χ c 1 (3872), χ c 1 (4140), χ c 1 (4274), χ c 1 (4685), χ b 1 (1 P ), χ b 1 (2 P ), and χ b 1 (3 P ) resonances in e + e − annihilation and γγ ∗ interactions will help the development and unification of theoretical predictions related to the electroweak decays of… 



X ( 3872 ) , X b , and the χ b 1 ( 3 P ) state

We discuss the possible production and discovery channels in ee and pp machines of the Xb, the bottomonium counterpart of X(3872) and the putative isoscalar analogue of the charged bottomonium-like

Two-Body Strong Decay of the 2P and 3P Charmonium states

Two-body open charm strong decays of the 2 P and 3 P charmonium states are studied by the Bethe-Salpeter(BS) method combined with the 3 P 0 model. The wave functions and mass spectra of the 2 P and 3

Evidence for X(3872)→J/ψπ^{+}π^{-} Produced in Single-Tag Two-Photon Interactions.

We report the first evidence for X(3872) production in two-photon interactions by tagging either the electron or the positron in the final state, exploring the highly virtual photon region. The

Two-photon transitions of charmonia on the light front

We investigate the two-photon transitions H c ¯ c → γ ∗ γ of the charmonium system in light-front dynamics. The light-front wave functions were obtained from solving the effective Hamiltonian based on
