Connecting the soil health–water quality nexus under surface‐irrigated conservation tillage

Journal of Environmental Quality, EarlyView.
Abstract Intense tillage degrades soil health, worsens soil structure, and accelerates nutrient and sediment transport to vulnerable water bodies. Unfortunately, few studies have measured both soil health and water quality under conservation tillage, particularly in semi‐arid furrow‐irrigated fields, limiting our understanding of tillage impacts in ...

$\eta \to \pi^0 \gamma \gamma$ decay within unitarized chiral perturbation theory [PDF]

, 2002
We improve the calculations of the $\eta \to \pi^0 \gamma \gamma$ decay within the context of meson chiral lagrangians. We use a chiral unitary approach for the meson-meson interaction, thus generating the $a_0(980)$ resonance and fixing the longstanding

Valons in mesons

Physical Review D, 1985
We present a systematic study of the valon distribution functions and valon structure functions for pions and kaons. The implications of our results for low-${p}_{T}$ inclusive reactions are emphasized. The complications with the structure function of strange valons are discussed and suggestions are made for future experiments to extract it from the ...

Integrating livestock and cropping systems: Interseeding cereal rye into corn for grazing

Journal of Environmental Quality, EarlyView.
Abstract Interseeding annual forages into growing corn may be an alternative for both cover and grazing in temperate regions of the United States. A 4‐year experiment evaluated the effect of interseeding cereal rye (Secale cereale) into corn for grazing after harvest on corn grain, forage biomass yield and quality, soil health, and estimated spatial ...

Meson B fragmentation function with consideration of mass corrections

Iranian Journal of Physics Research, 2019
Study of B meson (meson with the bottom quark flavor) in Large Hadron Collider (LHC) is of special importance so that the detector LHCb is devoted to investigate these types of mesons.

Unraveling the pattern of the XYZ mesons

Physics Letters B, 2014
We present a plausible mechanism for the origin of the XYZ mesons in the heavy meson spectra within a standard quark-model picture. We discuss the conditions required for the existence of four-quark bound states or resonances contributing to the heavy ...

Pseudoscalar meson and vector meson interactions and dynamically generated axial-vector mesons [PDF]

, 2014
The axial-vector mesons ${a}_{1}(1260)$, ${b}_{1}(1235)$, ${f}_{1}(1285)$, ${h}_{1}(1170)$, ${h}_{1}(1380)$, and ${K}_{1}(1270)$ are dynamically generated in the unitized chiral perturbation theory.

Isospin dependence of the eta prime meson production in nucleon-nucleon collisions [PDF]

, 2008
A comparison of the close-to-threshold total cross section for the eta prime production in pp --> pp eta prime and pn --> pn eta prime reactions constitutes a tool to investigate the eta prime meson structure and the reaction mechanism in the channels of

A Model of Mesons [PDF]

viXra, 2017
Detailed models of mesons have been derived in terms of real structured particles, in order to replace the formless quark/anti-quark singularities of standard QCD theory. Pion design is related to the muonic mass, and a Yukawa potential is calculated for the hadronic field.
