Matter of pure force: US, Israeli physicists hail China’s glueball discovery as ‘triumph’

The international physics community has hailed a Chinese-led discovery as a “triumph” after researchers presented the strongest evidence yet for the existence of the “glueball” – a mysterious particle made of pure force.
On Chinese social media, the conversation centred on whether the research could lead to a Nobel Prize.
The announcement was made last week at the International Conference on High Energy Physics in Natal, Brazil.
