Potentials between heavy-light mesons from lattice and inverse scattering theory
, 1997 We extend our investigation of heavy-light meson-meson interactions to a system consisting of a heavy-light meson and the corresponding antiparticle.

Ecography, EarlyView.The understory vegetation of boreal forests plays a crucial role in maintaining biodiversity by creating habitats, supplying food resources, and regulating microclimate and soil conditions. This essential layer is frequently affected by disturbances such as forest fires and clear‐cutting, which significantly alter understory communities and the ...

Two-index SU(N) theories from one flavor QCD to Steven Weinberg's ππ scattering legacy
Nuclear Physics BI review and improve on how two-index SU(N) gauge-fermion theories help access salient information about the large N vacuum and spectrum of QCD, super Yang Mills and meson-meson scattering.

Meson-meson scattering in two-dimensional QCD [PDF]
arXiv, 2019 We extend the formalism pioneered by Callan, Coote and Gross to investigate the meson-meson scattering within the framework of 't Hooft model, i.e., the two-dimensional QCD in the $N_c\to \infty$ limit. We derive the analytic expressions for various two-body meson-meson scattering amplitudes, concentrating on those quark diagrams which may be ...

The conservatism of prairie pollinators according to experts and empiricism
Insect Conservation and Diversity, EarlyView.We derived ecological conservatism values for prairie pollinators using expert opinion and analysis of remnant fidelity. Expert values were potentially biased and struggled to differentiate between remnant and non‐remnant prairie sites Empirical values showed advantages for pollinator‐based site assessment and prioritization in prairie regions ...

Insect Conservation and Diversity, EarlyView.Species‐specific responses of insects to forest management remain partly unfolded, thus ground beetles and their traits were studied in five different forestry treatments. Clear‐cuts and retentions had the most negative impact while habitat generalists and species with flexible breeding period have no response.
