The SuperKEKB Has Broken the World Record of the Luminosity

The SuperKEKB broke the world record of the luminosity in June 2020 in the Phase 3 operation. The luminosity has been increasing since then and the present highest luminosity is 4.65 x 10³⁴ cm⁻²s⁻¹ with β_{y}^{*} of 1 mm. The increase of the luminosity was brought with an application of crab waist,...

Descripción
Sumario:The SuperKEKB broke the world record of the luminosity in June 2020 in the Phase 3 operation. The luminosity has been increasing since then and the present highest luminosity is 4.65 x 10³⁴ cm⁻²s⁻¹ with β_{y}^{*} of 1 mm. The increase of the luminosity was brought with an application of crab waist, by increasing beam currents and by other improvements in the specific luminosity. In this paper, we describe what we have achieved and what we are struggling with. Finally, we mention a future plan briefly.
