Excited vector mesons: phenomenology and predictions for a yet unknown vector ss state with a mass of about 1.93 GeV

EPJ Web of Conferences, 2018
The firm understanding of standard quark-antiquark states (including excited states) is necessary to search for non-conventional mesons with the same quantum numbers.

Evolutionary Changes in Crassulacean Acid Metabolism (CAM) and Related Traits During the Diversification of Aichryson (Crassulaceae) on the Macaronesian Islands

Ecology and Evolution, Volume 16, Issue 1, January 2026.
We explore evolutionary changes in Crassulacean acid metabolism (CAM) and associated traits during the diversification of Aichryson (Crassulaceae) across the Macaronesian Islands. By combining field data, physiological measurements and phylogenetic analysis, we identify shifts in photosynthetic strategy linked to habitat transitions.

Scrutinizing Dark-Matter Scenarios with B → (K,$K^{\ast }$)$\overline{\mathit{\nu }}$ν Decays

Universe
Conceivable explanations of Belle-II measurements of a (surprising) excess of missing energy decays of the B meson to the K meson not covered by standard model neutrino–antineutrino pairs might be offered by additional contributions of dark matter ...

Differential cross section for γd → ωd using CLAS at Jefferson Lab

Physics Letters B, 2018
The cross section for coherent ω-meson photoproduction off the deuteron has been measured for the first time as a function of the momentum transfer t=(Pγ−Pω)2 and photon energy Eγ using the CLAS detector at the Thomas Jefferson National Accelerator ...

Exclusive heavy vector meson production at next-to-leading order in the dipole picture

Physics Letters B, 2021
We calculate exclusive production of a longitudinally polarized heavy vector meson at next-to-leading order in the dipole picture. The large quark mass allows us to separately include both the first QCD correction proportional to the coupling constant αs,

Leveraging Long‐Term Ecological Research Initiatives Into the One Health Synthesis

Ecology and Evolution, Volume 16, Issue 1, January 2026.
We address important ecological and evolutionary considerations for advancing a One Health perspective by drawing attention to faunal and ecosystem changes occurring through the Great Plains of North America that have strong implications for future risk of emerging pathogens including zoonoses.

The “regime shift extinctions” hypothesis and mass extinction of waterbirds in Hawaiʻi

Ecosphere, Volume 17, Issue 1, January 2026.
Abstract Studies of biodiversity loss commonly imply that species extinctions occurred as a direct result of initial human arrival and thus are attributable to stewardship failures of Indigenous Peoples. However, recent studies have suggested this assumption is not supported by the evidence, prompting a global reevaluation of existing assumptions.

A study of the vector meson ψ(4040) [PDF]

EPJ Web of Conferences, 2019
We investigate the well-known cc¯$c\overline c $ vector state ψ(4040) in the frame-work of a quantum field theoretical model. In particular, we study its spectral function and search for the pole(s) in the complex plane. Quite interestingly, the spectral
