1 Studying the ω properties in pA collisions via the ω→π 0 γ decay * Within transport calculations we study the production and decay of ω-mesons in pA reactions at COSY energies including elastic and inelastic ωN rescattering, the ω→π 0 γ Dalitz decay as well as π 0 N rescattering. The resulting invariant π 0 γ mass distributions indicate that in-medium modifications of the ω-meson may be obser...

Compared with the glass surface, photoluminescence intensity of CsPbBr3 quantum dots excited by 1200 nm femtosecond laser on surface Au island fiber film (AIF) is significantly enhanced. On other hand, decay AIF shows a fast average lifetime. The Photoluminescence enhancement effect was analysed spectrum, transmission electron microscope, absorption spectrum and decay. spectral changes are rela...

The integrable focusing nonlinear Schrödinger equation admits soliton solutions whose associated spectral data consist of a single pair conjugate poles arbitrary order. We study families such multiple-pole solitons generated by Darboux transformations as the pole order tends to infinity. show that in an appropriate scaling, there are four regions space-time plane where display qualitatively dis...

Temporal and spectral characteristics of prompt emission of gamma-ray burst (GRB) pulses are the primary observations for constraining the energizing and emission mechanisms. In spite of very complex temporal behavior of the GRBs, several patterns have been discovered in how some spectral characteristics change during the decaying phase of individual, well defined long (> few seconds) pulses. I...
