Tetraquarks in the 1/N expansion and meson-meson resonances [PDF]

open access: yes, 2016
Diquarks are found to have the right degrees of freedom to describe the tetraquark poles in hidden-charm to open-charm meson-meson amplitudes. Compact tetraquarks result as intermediate states in non-planar diagrams of the 1/N expansion and the ...

Two-index SU(N) theories from one flavor QCD to Steven Weinberg's ππ scattering legacy

open access: yesNuclear Physics B
I 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.

Neonate mortality in mountain caribou: Patterns of predation during onset of a wolf reduction program

open access: yesThe Journal of Wildlife Management, EarlyView.
We used an individual‐based movement method, supported by camera trap data, to assess changes in neonate caribou mortality patterns before and after wolf reduction began in the Itcha‐Ilgachuz mountain caribou subpopulation range, British Columbia, Canada.

Confining Bond Rearrangement in the Random Center Vortex Model

open access: yes, 2016
We present static meson-meson and baryon--anti-baryon potentials in Z(2) and Z(3) random center vortex models for the infrared sector of Yang-Mills theory, i.e., hypercubic lattice models of random vortex world-surfaces.

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

open access: yes, 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

Asphalted parking lots are environmental filters for multiple propagule dispersal and pollination strategies

open access: yesNordic Journal of Botany, EarlyView.
Understanding community assembly for wild species in anthropogenic settings has become increasingly important as biodiversity and ecosystem services are threatened by development pressures. Urban hardscape habitats such as parking lots are widespread, extreme, terrestrial anthropogenic environments that influence plant community assembly by way of ...

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

open access: yes, 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

Meson turbulence at quark deconfinement from AdS/CFT

open access: yesNuclear Physics B, 2015
Based on the QCD string picture at confining phase, we conjecture that the deconfinement transition always accompanies a condensation of higher meson resonances with a power-law behavior, “meson turbulence”.
