Model Calculations for Cosmogenic Nuclides in Meteorites and the Lunar Surface. 1. Long‐lived Radionuclides

open access: yesMeteoritics &Planetary Science, EarlyView.
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.

Isospin breaking in the pion-nucleon coupling constant and the nucleon-nucleon scattering length

open access: yesЯдерна фізика та енергетика, 2016
Charge independence breaking (CIB) in the pion-nucleon coupling constant and the nucleon-nucleon scattering length is considered on the basis of the Yukawa meson theory.

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

open access: yesEPJ 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 ...

Pion-pion scattering in two dimensions [PDF]

open access: yesPhysical Review D, 1999
Massive two-flavor QED_2 is known to have many similarities to the two-flavor QCD_4. Here we compare the - scattering amplitudes (actually an analog process in QED_2) of the two theories. The QED_2 amplitude is computed from the bosonized version of the model while the QCD_4 amplitude is computed from an effective low energy chiral Lagrangian.

Affective CT‐touch attenuates cortical responses and subjective attention during temporal summation of second pain

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The study investigated the modulatory effects of affective touch on temporal summation of second pain (TSSP) in 32 romantic couples (N = 64). The design included a dyadic session (partner's CT‐optimal stroking vs. static touch) and an individual session (robotic CT‐touch vs. vibration control).

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

open access: yesPhysics 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 ...

Neue Methode zum Neutrinonachweis: Kohärente Streuung von Neutrinos an Atomkernen

open access: yesPhysik 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

Pion nucleus Drell–Yan process and parton transverse momentum in the pion

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We present a thorough analysis of unpolarized Drell–Yan (DY) pair production in pion–nucleus scattering. On the nucleus side, we use nuclear parton distributions along with parametrisations of the nucleon partonic transverse distribution available in the

Pion generalized parton distributions and light-front wave functions in the Nambu–Jona-Lasinio model

open access: yesNuclear Physics B, 2021
Pion generalized parton distributions and light-front wave functions are investigated in the framework of Nambu–Jona-Lasinio model. The properties of pion generalized parton distributions and light-front wave functions are examined separately. Proceeding
