  2. About Belle II

Why in the News?

The High Energy Accelerator Research Organisation (KEK) completed the much-awaited ‘rolling-in’ of the Belle-II experiment in Tsukuba, Japan.

News in Brief

  • This experiment is designed to study violations of the Standard Model of particle physics.
  • A grand collaboration of 700 scientists from 23 countries, Belle-II has significant Indian participation both on experimental and theoretical sides.
About Belle II

India in the Belle II

  • Belle-II has a significant Indian participation both on experimental and theoretical sides.
  • It is a six-layer, highly sensitive particle detector.
  • The fourth layer which is at the heart of Belle-II, has been built by Indian scientists.
  • In 1998, when Indians in this field were working mostly with CERN (European Organisation for Nuclear Research), KEK approach India to participate in this project.
  • Scientists from various institute participated in this project.

What is Particle Physics?

  • It is the branch of physics that deals with the properties, relationships and interactions of subatomic particles.
  • Many technologies have been developed during these pioneering investigations that later find wide uses.
  • Particle accelerators are used to produce medical isotopes for research and treatment (for example, isotopes used in PET imaging), or used directly in external beam radiotherapy.

Why is a Particle Physics Experiment conducted?

  • The primary goal is to find and understand what physics may lie beyond the standard model.
  • There are several powerful experimental reasons to expect new physics, including dark matter and neutrino mass.
  • There are also theoretical hints that this new physics should be found at accessible energy scales.
