Nonperturbative partonic quasidistributions of the pion from chiral quark models

open access: yesPhysics Letters B, 2017
We evaluate nonperturbatively the quark quasidistribution amplitude and the valence quark quasidistribution function of the pion in the framework of chiral quark models, namely the Nambu–Jona-Lasinio model and the Spectral Quark Model.

Neurocognitive Dynamics of Translating Information From a Spatial Map Into Action

open access: yesPsychophysiology, Volume 63, Issue 3, March 2026.
ABSTRACT How do we translate information from a spatial map to action in our immediate surroundings? Despite the widespread use of various tools for orientation, from paper maps to GPS, this fundamental question remains unanswered in our understanding of human spatial navigation.

Internal structure of the Tcc(3875)+ from its light-quark mass dependence

open access: yesPhysics Letters B
We employ a chiral effective field theory-based approach to connect DD⁎ scattering observables at the physical and variable pion masses accessible in lattice QCD simulations.

Disentangling Respiratory Phase‐Dependent and Phase‐Independent Components of Anticipatory Cardiac Deceleration

open access: yesPsychophysiology, Volume 63, Issue 3, March 2026.
ABSTRACT The heart does not beat like a metronome: varying parasympathetic input to the heart leads to constant heart rate variability. Vagal cardiomotor neuron activity is coupled to the respiratory cycle, leading to respiratory sinus arrhythmia (RSA), a permanent oscillation of heart rate synchronized to respiration.

Dalitz plot studies of D0 → KS0π+π− decays

open access: yesEPJ Web of Conferences, 2012
The availaible data on the D0 → KS0π+π− decays are analysed in the framework of the quasi two-body QCD factorization approximation. The annihilation, via Wexchange, amplitudes are added to the weak-decay tree amplitudes.

Postoperative posterior ischemic optic neuropathy (PION) following right pterional meningioma surgery

open access: yesAnnals of Indian Academy of Neurology, 2016
Postoperative visual loss (POVL) is an unpredictable complication of nonocular surgeries. Posterior ischemic optic neuropathy (PION) is particularly feared in spinal surgeries in the prone position.

Nonequilibrium Pion Distribution within the Zubarev Approach

open access: yesParticles, 2020
We discuss how the non-equilibrium process of pion production within the Zubarev approach of the non-equilibrium statistical operator leads to a theoretical foundation for the appearance of a non-equilibrium pion chemical potential for the pion ...

Galactic Cosmic Ray Ionization on Uranus; Geomagnetic Latitude Dependencies

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Galactic Cosmic Rays (GCRs) are a major source of atmospheric ionization, influencing ion abundance, aerosol formation, and electrical processes. GCR‐induced effects are expected to be more pronounced on Uranus than planets closer to the Sun for two reasons; reduced solar irradiance, and weaker solar modulation of incident GCR.

The charged and neutral pion masses revisited

open access: yesPhysics Letters B, 2019
Results from neutrino mass and oscillation experiments now set the mass of the muon neutrino to less than 2 eV/c2. This fact, together with our former measurement of the muon momentum in pion decay at rest, pμ+=(29.79200±0.00011) MeV/c, allows us to ...
