Coupled channels calculation of a pion-Lambda-nucleon quasibound state
, 2010 We extend the study of a JP=2+, I=3/2 pion-Lambda-nucleon quasibound state [Phys. Rev. D 78, 014013 (2008)] by solving nonrelativistic Faddeev equations, using 3S1-3D1, Lambda N - Sigma N coupled channels Chiral Quark Model local interactions, and pion ...

Confinement and cut-off: a model for the pion quark distribution function [PDF]
, 2003 The pion structure function is investigated in a simple pseudo-scalar coupling model of pion and constituent quark fields. The imaginary part of the forward Compton scattering amplitude is evaluated.

Dynamics of Purification in Cu2O
physica status solidi (b), EarlyView.Rydberg excitons in Cu2O have been shown to be highly efficient in neutralizing and screening charged impurities, which is referred to as purification. In this manuscript, the dynamics of the purification process are investigated under varying probe exciton‐ and plasma density. The transient absorption of Rydberg excitons is analyzed and five different

Le vote blanc et nul en Wallonie : analyse écologique et individuelle
Belgeo, 2010 Blank and null votes are probably the electoral behaviour least taken into account by electoral studies. Though, in a democracy like Belgium, these votes are far from negligible and offer an untypical geography which underlines border areas.

Coherent Pion Production in Neutrino Nucleus Scattering
, 2016 In this article, we study the coherent pion production in neutrino-nucleus interaction in the resonance region using the formalism based on partially conserved axial current (PCAC) theorem which relates the neutrino-nucleus cross section to the pion ...

Expecting the Next Coup? The Unchallenged Brazilian Military's Bargaining Power
Bulletin of Latin American Research, EarlyView.The civil‐military relations in Brazil have faced criticism due to weak political institutions and significant military autonomy, resulting in a regression of democratisation. This article posits that the shortcomings in Brazilian civil‐military relations have historical roots, with military prerogatives established in the early twentieth century and ...

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

Neutrino-induced coherent pion production off nuclei reexamined
, 2009 It is pointed out that so far all theoretical estimates of coherent pion production off nuclei induced by neutrinos rely on the 'local approximation' well known in photonuclear physics. The effects of dropping this approximation are discussed.
