The sigma-meson exchange contribution to the muonic hydrogen Lamb shift [PDF]
EPJ Web of Conferences, 2019 The sigma(ξ)meson exchange contribution to the potential of the muon-proton interactionin muonichydrogen inducedbythe ξ-meson coupling to two photons is estimated. The transition form factor ξ → γγ is deduced from the quark model and experimental data on

Meson-Baryon Scattering in QCD_2 for any Coupling
, 2003 Extending earlier work on strong-coupling meson-baryon scattering in QCD_2, we derive the effective meson-baryon action for any value of the coupling constant, in the large-N_c limit.

Diverse Prairie Mixtures Stabilize Biomass Yields for Sustainable Aviation Fuel Production
PLANTS, PEOPLE, PLANET, EarlyView.Meeting global demand for sustainable aviation fuel will require the additional production of vast quantities of plant biomass, which does not compete with food production or degrade sensitive ecosystems. Our multisite experiment shows that sowing diverse native prairie seed mixes—and managing them without intensive inputs—yields a more reliable ...

Hadronic charmed meson decays involving tensor mesons [PDF]
Physical Review D, 2003 Charmed meson decays into a pseudoscalar meson P and a tensor meson T are studied. The charm to tensor meson transition form factors are evaluated in the Isgur-Scora-Grinstein-Wise (ISGW) quark model. It is shown that the Cabibbo-allowed decay $D_s^+\to f_2(1270) ^+$ is dominated by the W-annihilation contribution and has the largest branching ratio ...

PLANTS, PEOPLE, PLANET, EarlyView.American ginseng is a shade‐obligate, North American medicinal plant that is widely traded and used internationally. To meet global demand, ginseng is cultivated in forest farms in the Appalachian region of the USA and field‐based artificial shade farms in two regions: Ontario, Canada and Wisconsin, USA. We conducted social research leveraging in‐depth

Distillation of scalar exchange by coherent hypernucleus production in antiproton–nucleus collisions
Physics Letters B, 2017 The total and angular differential cross sections of the coherent process p¯+AZ→ΛA(Z−1)+Λ¯ are evaluated at the beam momenta 1.5÷20 GeV/c within the meson exchange model with bound proton and Λ-hyperon wave functions.

Meson spectroscopy and properties using Dyson-Schwinger equations [PDF]
, 2006 We study pseudoscalar and scalar mesons using a practical and symmetry preserving truncation of QCD's Dyson-Schwinger equations. We investigate and compare properties of ground and radially excited meson states.

Pest Management Science, EarlyView.Beech residues left in shaded or semi‐shaded conditions pose a substantial risk of local Taphrorychus bicolor population outbreaks. The rapid removal or placement of residues in sun‐exposed locations can help mitigate this risk. Abstract BACKGROUND The bark beetle Taphrorychus bicolor has been traditionally classified as a secondary pest of European ...
