One of the main goals studying semileptonic decays in flavor physics is to gain a better understanding hadronic transitions nonperturbative region Quantum Chromodynamics. This involves measuring Cabibbo-Kobayashi-Maskawa matrix elements, form factors, and comparing them with theoretical predictions.

Abstract In today's rapidly evolving society, the establishment of a learning society is paramount. The lifelong education system (LLES) plays crucial role in enriching individuals' intellectual and emotional landscapes, fostering continuous growth, instilling habit learning. However, traditional systems often have limitations regarding accessibility, openness, resource‐sharing, limiting opportunities for dampening enthusiasm it. To address these limitations, it hypothesized that integrating...
