QED effects in the pseudoscalar meson sector [PDF]

, 2015
A bstractIn this paper we present results on the pseudoscalar meson masses from a fully dynamical simulation of QCD+QED, concentrating particularly on violations of isospin symmetry.

The spread of non‐native species

Biological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

The non-perturbative unquenched quark model

EPJ Web of Conferences, 2017
In recent years states in the quarkonium spectrum not expected in the naive quark model have appeared and created a lot of interest. In the theoretical side the study of the effect of meson-meson thresholds in the spectrum have been performed in ...

(Anti-)Stokes scattering on kinks

Journal of High Energy Physics, 2023
At leading order, there are three inelastic scattering processes beginning with a quantum kink and a fundamental meson. Meson multiplication, in which the final state is a kink and two mesons, was treated recently.

Developing a macroecology for human‐altered ecosystems

Ecography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

In-medium Properties of the η′-Meson from Photonuclear Reactions

EPJ Web of Conferences, 2012
Investigations of in-medium properties of the η′-meson are presented. The photoproduction of η′-mesons off 12C, 40Ca, 93Nb and 208Pb nuclei has been measured with the Crystal Barrel/TAPS detector system at the ELSA accelerator in Bonn.

Convergence of the barycentre of measures from Fuchsian action groups [PDF]

, 2013
We prove the pointwise ergodic convergence of the sequence of barycentres of empirical measures which are defined from the action of Fuchsian groups and by maps valuated in CAT(0)−spaces.

$\delta$ meson effects on neutron stars in the modified quark-meson coupling model

, 2008
The properties of neutron stars are investigated by including $\delta$ meson field in the Lagrangian density of modified quark-meson coupling model. The $\Sigma^-$ population with $\delta$ meson is larger than that without $\delta$ meson at the beginning,

Interactions of heavy-light mesons [PDF]

, 1999
The potential between static-light mesons forming a meson-meson or a meson-antimeson system is calculated in quenched and unquenched SU(3) gauge theory.
