Coupled-channel-induced $$S{-}D$$ mixing of Charmonia and testing possible assignments for Y(4260) and Y(4360)

Abstract

The mass spectrum and the two-body opencharm decays of the J PC = 1 −− charmonium states are studied with the coupled-channel effects taken into account. The coupled-channel-induced mixing effects among the excited vector charmonia are studied. Based on our calculations of the masses and the decay widths, we find that the tension between the observed properties of Y (4260)/Y (4360) and their conventional charmonia interpretations could be softened.

Synthesis of epoxy‐ended hyperbranched polyesters with reinforcing and toughening function for diglycidyl ether of bisphenol‐A

“…However, the application of epoxy resins is restricted by their inherent brittleness. To eliminate this drawback, different tougheners, including rubbers, glass particles and engineering thermoplastics [9][10][11][12], have been used to modify epoxy resins. However, these modifications often cause the deterioration of processing performance, glass transition temperature (T g ) and mechanical properties of epoxy resins.…”

Resolving the Unpaired‐Electron Orbital Distribution in a Stable Organic Radical by Kondo Resonance Mapping

Pyroelectric Energy Harvesting Using Ferroelectric Ba1−xCaxTiO3

“…By using differential scanning calorimetry, it was confirmed that the Curie temperature, T C , of Ba 1Àx Ca x TiO 3 was above 369 K, which is consistent with previous studies. [25,27,28] A typical heat capacity of Ba 1Àx Ca x TiO 3 was approximately 0.16 J K À1 . The electric displacement, D, of the square-plate samples was measured by the varying electric field, E, at room temperature by means of the double-wave method.…”
