Relativistic Corrections to $e^+e^- \to J/\psi + \eta_c$ in a Potential Model

open access: yes, 2006
We compute relativistic corrections to the process $e^+e^- \to J/\psi + \eta_c$ and find that they resolve the discrepancy between theory and experiment.Comment: 3 pages, talk given at Quark Confinement and the Hadron Spectrum VII, Ponta Delgada ...

An upgraded key for identifying all native species, subspecies and varieties of the genus Carex (Cyperaceae) in Europe and the Caucasus

open access: yesNordic Journal of Botany, Volume 2025, Issue 8, August 2025.
The last pan‐European key to Carex taxa was published in 1980 by Chater. Since that time several new species have been described, and numerous nomenclatural changes, including the recognition that the former genus Kobresia should be incorporated into Carex as C. subg. Euthyceras, have been made. This article provides a comprehensive key to identify all

CMIP6 Representation of Declining Sea Ice and Arctic Cyclones in the Current Climate

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 14, 28 July 2025.
Abstract The Arctic climate system is changing rapidly with important implications in the Arctic and beyond. The interaction between the sea ice and Arctic cyclones makes it an important topic to be understood in the warming climate. We analyzed an ensemble of Coupled Multimodel Intercomparison Project (CMIP6) model simulations from 1985 to 2014 to ...

A first assessment of operator compliance and dolphin behavioural responses during swim-with-dolphin programs for three species of Delphinids in the Azores [PDF]

open access: yes, 2019
The popularity of swim-with wild dolphin programs around the world is fast growing, with the studies required to investigate their impact lagging behind. In the Azores, species targeted include the short-beaked common (Delphinus delphis), the bottlenose (
