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

Physics 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.

Dalitz plot studies of D0 → KS0π+π− decays

EPJ 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.

Not All Rules Are Equal: Rare Conditional Rules Shape Behaviour but Yield to Global Probability in Passive Listening

European Journal of Neuroscience, Volume 63, Issue 8, April 2026.
The auditory system rapidly detects violations of sound regularities, but it remains unclear whether rarely encountered sounds violating such established regularities (i.e., deviants) themselves can inform prediction. In an adapted oddball paradigm, behavioural results show that conditional rules associated with rarely encountered deviants can be ...

Sensitivity to the pion-nucleon coupling constant in partial-wave analyses of elastic pi-N and NN scattering and pion photoproduction

, 1999
We summarize results obtained in our studies of the pion-nucleon coupling constant. Several different techniques have been applied to pi-N and NN elastic scattering data, and the existing database for single-pion photoproduction.

Model calculations for cosmogenic nuclides in meteorites and the lunar surface. 1. Long‐lived radionuclides

Meteoritics &Planetary Science, Volume 61, Issue 4, Page 600-620, April 2026.
Abstract Production rates for the cosmogenic radionuclides 10Be, 14C, 26Al, 36Cl, 41Ca, 53Mn, and 60Fe in a large variety of meteorites, that is, ordinary chondrites (H, L, LL), carbonaceous chondrites, HED meteorites, ureilites, Martian meteorites, and iron meteorites and in the uppermost ~2 m of the lunar surface are modeled.

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.

Pion-Nulceon Scattering and the Structure of the Pion [PDF]

Progress of Theoretical Physics, 1957
Effects of the structure'' of the pion on the pionnucleon scattering are discussed. A formal expression of the interaction kernel far the nucleon- antinucleon propagator is given, from which the effective Hamiltonian'' for the emission and absorption of one pion and that for two pions is derived, respectively.

Heartbeat‐Evoked Responses in M/EEG: A Systematic Review of Methods With Suggestions for Analysis and Reporting

Psychophysiology, Volume 63, Issue 4, April 2026.
ABSTRACT Heartbeat‐evoked responses (HER), as measured by electroencephalography (EEG) or magnetoencephalography (MEG), represent neural activity time‐locked to heartbeats and are widely used as a marker of cardiac interoception in the study of brain–body interactions.

Neue Methode zum Neutrinonachweis: Kohärente Streuung von Neutrinos an Atomkernen

Physik in unserer Zeit, Volume 57, Issue 2, Page 79-83, March 2026.
Neutrinos sind sehr schwer nachweisbare Elementarteilchen, die selbst in riesigen Experimenten kaum Spuren hinterlassen. Nun ist es erstmalig gelungen, diese winzigen Teilchen mit einer vergleichsweise kleinen Messapparatur an einem Kernreaktor über die sogenannte kohärente elastische Neutrino‐Kern‐Streuung zu beobachten. Zusammenfassung Neutrinos sind
