    Observation of Ultra Fine Structures in Energy Levels of Prolate Nuclei

    Hassan Hassanabadi · Hadi Sobhani

    This article contains a discussion in which we showed that observation of splitting in the energy levels of prolate nuclei, is possible. Similar effects is atomic physics is known as Zeeman effect which is well-known, but in nuclear physics such topic has not been discussed and mentioned if it is possible or is not. In this article, after introducing deformation in commutation relation in three dimensional, these relations has been used in X(3) model. After enough derivation, we evaluate energy spectrum relation for considered system which has splitting. Because of considerations during the derivation, we'd like to call such effect as ultra fine structures in energy levels. At the end some plots have been depicted which illustrate the results.

    Study of a background reconstruction method for the measurement of D-meson azimuthal angular correlations

    Long Ma🇨🇳 · Xin Dong🇺🇸 · Huan-Zhong Huang🇨🇳 · Yu-Gang Ma🇨🇳

    We study experimental background reconstruction methods for the measurement of correlation using a PYTHIA simulation. Like-sign and side-band background methods that are widely used in the experimental measurements of single -meson production yields were deployed for the correlation background study. It is found that the like-sign method which well describes the combinatorial background of single meson yields fails to reproduce the correlated background in the correlation measurement, while the side-band background method yields a good description of the background for both the single yields and of the correlated background of the correlation measurement.
