The Belle II detector at SuperKEKB in Japan recorded its first e+e– collisions since the summer of 2022 on February 20th. This marked the end of a scheduled long shutdown during which a new vertex detector and an improved beam pipe at the collision point were installed to handle expected increases in luminosity and backgrounds from the beams. In addition, other enhancements such as improved radiation shielding and measures to improve data collection performance were also implemented during this time.

The fully instrumented Belle II detector had its first collisions recorded in March 2019. Its primary goal is to uncover new phenomena through precise analysis of B mesons and other particles produced by the SuperKEKB accelerator. With a long-term objective of accumulating a dataset 50 times larger than that of the former Belle experiment, Belle II is set to push the boundaries of particle physics research.

Excitement and anticipation filled the control room on February 20th as Run 2 in the Belle II experiment began. This milestone represents a major step forward for both the experiment and the SuperKEKB accelerator, setting the stage for groundbreaking discoveries and advancements in particle physics research. The dedication and hard work of those involved in upgrades and preparations for Run 2 have paid off, and scientists are eagerly looking forward to gaining valuable knowledge and insights from the data collected during this phase of the experiment.

The successful start of Run 2 marks a major milestone in Belle II’s journey towards uncovering new phenomena through precise analysis of B mesons and other particles produced by SuperKEKB accelerator. With its long-term objective to accumulate a dataset 50 times larger than that of its predecessor, Belle II is poised to push beyond traditional boundaries in particle physics research.
