Hello readers! Today, we are excited to delve into the fascinating world of MicroBooNE and explore its groundbreaking research. The MicroBooNE collaboration has recently accomplished an unprecedented feat—the measurement of the cross section of Cabibbo-suppressed Λ (Lambda) baryon production. Let's take a closer look at their remarkable findings and the significance they hold. What is MicroBooNE? MicroBooNE, short for Micro Booster Neutrino Experiment, is a groundbreaking particle physics experiment located at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois. Its primary objective is to study neutrino interactions using a state-of-the-art liquid argon time-projection chamber (LArTPC). By examining the properties and behavior of neutrinos and their interactions with matter, MicroBooNE aims to unveil the mysteries surrounding these elusive particles. Distinguishing MiniBooNE and MicroBooNE Before delving into the recent findings, it's important to disting...

Today, we delve into the fascinating world of neutrinos and explore the recent breakthrough made by the Borexino collaboration in measuring CNO neutrino fluxes. Neutrinos are elusive particles that originate from various astrophysical sources, and their study has unveiled valuable insights into the workings of the universe. In this post, we will discuss solar neutrinos, the CNO cycle, the significance of Borexino's measurements, and provide an overview of their groundbreaking paper. Solar Neutrinos and Neutrino Flux in Nuclear Reactions: Solar neutrinos, subatomic particles with no electric charge and minuscule mass, are generated within the Sun's core through nuclear reactions, particularly the proton-proton chain where hydrogen nuclei fuse to form helium. At each step of this process, various types of neutrinos are emitted, constituting the primary source of solar neutrinos. The quantity of solar neutrinos is truly astonishing – in a mere one-second interval, approximately 65...
