Threshold effects in hadron spectrum: a new spectroscopy?

open access: yesEPJ 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.

Life Under the Snow: Camera Trap Videos Capture Year‐Round Lemming Activity and Behavior

open access: yesIntegrative Zoology, EarlyView.
We developed an automated camera system capable of recording year‐round videos of lemmings beneath the snow in the High Arctic. We demonstrate the potential of this system to document lemming activity and behaviors. Our results show that it effectively monitors lemming relative abundance with temporal precision unmatched by other methods.

Probing kaon meson condensations through gravitational waves during neutron star inspiral phases

open access: yesPhysics Letters B
Gravitational waves from binary neutron star merger events have shown unparalleled advantages in deciphering the stellar internal structure, yet it remains underexplored to seek clues about kaon meson condensations inside massive neutron stars through ...

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

open access: yesPhysics 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.

Chromosome‐Level Genome Assembly of Strauchbufo raddei and Multi‐Omic Insights Into Drought Adaptation

open access: yesIntegrative Zoology, EarlyView.
ABSTRACT Understanding how amphibians adapt to terrestrial and arid environments is important for elucidating vertebrate terrestrialization. In this study, we present the first chromosome‐level, high‐quality genome assembly of Strauchbufo raddei, constructed using PacBio HiFi long‐read sequencing and Hi‐C scaffolding. The assembled genome is 4.47 Gb in

Light meson mass spectra and pion electromagnetic form factor as a bound system in 3 + 1 dimensional QCD

open access: yesResults in Physics, 2018
We investigate the Bethe-Salpeter-like amplitude in 3 + 1 dimensions. This involves a system comprising a quark and antiquark combined by gauge fields to satisfy gauge invariance. We derive the equation of motion for this system and construct a series of

Precision measurement of D meson mass differences [PDF]

open access: yes, 2013
Using 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 D 0 mass.

The PhenoChange network protocol for monitoring leaf phenology in tropical dry ecosystems using phenocameras

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Tropical dry ecosystems (TDEs) cover half of the tropics and play a key role in global carbon dynamics. TDEs present distinct canopy and ground layers that often exhibit contrasting phenological patterns. On‐the‐ground observations of phenology by the human eye, though valuable, may suffer from limited temporal resolution and observer biases ...
