The width of the Δ-resonance at two loop order in baryon chiral perturbation theory

Physics Letters B, 2016
We calculate the width of the delta resonance at leading two-loop order in baryon chiral perturbation theory. This gives a correlation between the leading pion–nucleon–delta and pion–delta couplings, which is relevant for the analysis of pion–nucleon ...

Effects of the Pion-Pion Resonance and the Three-Pion Resonance or Bound State on Neutral-Pion Decay [PDF]

Physical Review, 1961
The dispersion method was applied to the problem of neutral-pion decay. lt is shown that a pion-pion P-wave resonance can produce a large effect in the decay matrix element. The contribution is related to the semifundamental constant which determines the rate of photoproduction of pions from pions.

Idiosyncratic Eye‐Movement Patterns to Faces Are Associated With Differences in Neural Processing: Evidence From Behavioral and Event‐Related Potential Responses

European Journal of Neuroscience, Volume 64, Issue 8, October 2026.
We manipulated fixation locations on faces during an identification task. The results demonstrated that participants who prefer to observe the eyes performed better and showed larger P1‐to‐N170 peak‐to‐peak amplitudes when fixating on the eyes than on the nose, whereas those who prefer to observe the center of faces showed no significant differences ...

Evaluation of the two lightest quark masses

Ядерна фізика та енергетика, 2017
Simple relations between the masses of the two lightest up and down quarks were obtained on the basis of the simple physically based model compatible with the present-day theory of strong interactions, i.e. with quantum chromodynamics.

Nonperturbative partonic quasidistributions of the pion from chiral quark models

Physics 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.

Cardiovascular Responses to Natural and Auditory Evoked Slow Waves Predict Post‐Sleep Cardiac Function

Journal of Sleep Research, Volume 35, Issue 5, October 2026.
ABSTRACT The importance of sleep as a key component of cardiovascular health has been increasingly recognized. Our previous research demonstrated that auditory‐enhanced slow waves increase cardiac function, but the underlying mechanisms behind these beneficial effects remain uncertain. In this study, we examined the influence of two types of slow waves

Variability in Preprocessing and Analysis of the Error‐Related Negativity in Adult Response‐Conflict Studies: A Systematic Review

Psychophysiology, Volume 63, Issue 10, October 2026.
ABSTRACT The analysis of EEG (electroencephalography) data affords many defensible choices, creating substantial researcher degrees of freedom. While stimulus‐locked components such as the N400 show wide methodological variability and incomplete reporting, it has been unclear whether this generalizes to the response‐locked error‐related negativity (ERN)

Dispersion relations for hadronic light-by-light scattering and the muon g – 2

EPJ Web of Conferences, 2018
The largest uncertainties in the Standard Model calculation of the anomalous magnetic moment of the muon (g – 2)μ come from hadronic effects, and in a few years the subleading hadronic light-by-light (HLbL) contribution might dominate the theory error ...

QCD phase structure at finite isospin chemical potential and smaller-than-physical quark mass [PDF]

EPJ Web of Conferences
Introduction of a nonzero isospin chemical potential in QCD leads to the emergence of a pion condensed phase at sufficiently large μI, bounded by a second order transition line. At zero temperature the pion condensate appears at μI = mπ/2.
