Decay of kaonium in a chiral approach

, 2011
The decay of the K+K- hadronic atom kaonium is investigated non-perturbatively using meson-meson interaction amplitudes taken from leading order chiral perturbation theory in an approach adapted from that proposed by Oller and Oset [18].

Toward the excited isoscalar meson spectrum from lattice QCD [PDF]

, 2013
We report on the extraction of an excited spectrum of isoscalar mesons using lattice QCD. Calculations on several lattice volumes are performed with a range of light quark masses corresponding to pion masses down to about ~400 MeV.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Production of Eta Mesons in Proton-Proton Collisions Close to Threshold

, 2004
A brief experimental overview on the close-to-threshold eta meson production in proton-proton interactions is presented and the available observables in measurements with unpolarized and polarized beam and target are discussed.Comment: 4 pages; Presented

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 ...

Persistence and dynamic of forest snails in the Western Carpathians over the last 40 thousand years

Boreas, EarlyView.
The glacial/interglacial cycles have shaped the landscape of temperate Europe for the past 2.5 million years, with open landscapes prevailing during the glacial and forested landscapes during the interglacial periods. However, the survival and recolonization strategies of temperate forest species during glacial phases remain poorly understood and hotly

Mass Spectrum of Noncharmed and Charmed Meson States in Extended Linear-Sigma Model

Particles
The mass spectrum of different meson particles is generated using an effective Lagrangian of the extended linear-sigma model (eLSM) for scalar and pseudoscalar meson fields and quark flavors, up, down, strange, and charm.

Threshold effects in hadron spectrum: a new spectroscopy?

EPJ Web of Conferences, 2018
The exploration of energies above the open-flavor threshold in the meson spectra has led to the appearance of unexpected states difficult to accommodate in the naive picture of a bound state of a quark and an antiquark.

Resonance dynamics in the coherent η meson production in the (p,p′) reaction on the spin–isospin saturated nucleus

Physics Letters B, 2014
For the forward going proton and η meson, the coherent η meson production in the (p,p′) reaction on the spin–isospin saturated nucleus occurs only due to the η meson exchange interaction between the beam proton and nucleus.

Precision measurement of D meson mass differences [PDF]

, 2013
A bstractUsing three- and four-body decays of D mesons produced in semileptonic b-hadron decays, precision measurements of D meson mass differences are made together with a measurement of the D0 mass. The measurements are based on a dataset corresponding
