Another giant has got into its place

Belle II in its roll-in position

Belle II in its roll-in position


On 11 April 2017, the Belle II detector at the High Energy Accelerator Research Organization (KEK) in Japan was rolled in from its construction area to the interaction region of the SuperKEKB particle accelerator. This event marks another milestone in our pursuit to decode the fundamental new principles of nature (‘new physics’) beyond that encompassed by the standard model of particle physics. Complementary to the direct search being carried out at the energy frontier experiments of LHC, Belle II will be a world-leading experiment on the intensity frontier by indirectly probing new physics with intense e+e- beams and extremely sensitive detector.

Speaking of the ‘sensitive’ detector the Belle-II group at TIFR is leading the design and construction of the silicon vertex detector (SVD) of the experiment (For more on the SVD please see TIFR Science News). This device will be able to measure the position of charged particles emanating from e+e- collisions to an accuracy of 15-20 microns. Given the delicate nature of the SVD, it is not part of the current roll-in of the experiment and will be installed once one has a better understanding of various beam-related backgrounds. We are expecting the full Belle II detector to be operational by the end of 2018.

The Indian contribution to the Belle-II experiment has been publicised in the media.
