ArXiv

Analysis

This paper investigates the nuclear structure of lead isotopes (specifically $^{184-194}$Pb) using the nuclear shell model. It's important because understanding the properties of these heavy nuclei helps refine our understanding of nuclear forces and the behavior of matter at the atomic level. The study provides detailed calculations of energy spectra, electromagnetic properties, and isomeric state characteristics, comparing them with experimental data to validate the model and potentially identify discrepancies that could lead to new insights.
Reference

The paper reports results for energy spectra, electromagnetic properties such as quadrupole moment ($Q$), magnetic moment ($μ$), $B(E2)$, and $B(M1)$ transition strengths, and compares the shell-model results with the available experimental data.

ArXiv

Analysis

This paper investigates new physics models that extend the Standard Model by introducing exotic particles that interact with both leptons and gluons. It explores the parameter space of these models, considering various effective operators and their potential collider signatures. The focus on asymmetric portals and the exploration of different SU(3) and SU(2) quantum numbers for the exotic states are key aspects of the research.
