Meson-meson scattering in lattice QED2+1 [PDF]
Nuclear Physics B - Proceedings Supplements, 1993 Scattering phase shifts of a meson-meson system in staggered 3-dimensional lattice QED are computed. The main task of the simulation is to obtain a discrete set of two-body energy levels. These are extracted from a 4-point time correlation matrix and then used to obtain scattering phase shifts.

A Hybrid Semi‐Inverse Variational and Machine Learning Approach for the Schrödinger Equation
Advanced Physics Research, EarlyView.A hybrid semi‐inverse variational and machine‐learning framework is presented for solving the Schrödinger equation with complex quantum potentials. Physics‐based variational solutions generate high‐quality training data, enabling Random Forest and Neural Network models to deliver near‐perfect energy predictions.

Vector-meson production and vector meson dominance
European Physical Journal C: Particles and Fields, 2021 We consider the fidelity of the vector meson dominance (VMD) assumption as an instrument for relating the electromagnetic vector-meson production reaction $$e + p \rightarrow e^\prime + V + p$$ e + p → e ′ + V + p to the purely hadronic process $$V + p ...

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.

Classifying avian drinking behaviour: ecological insights and implications in a changing world
Biological Reviews, EarlyView.ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns

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.
