An international research group such as Tsukuba University announced that one of the elementary particles, which are the basic particles that make up a substance, has a mass analyzed from experiments that is larger than expected. It is said that further verification is necessary because it may force the revision of the "standard theory" which is the pillar of physics.
The "Standard Model" is a theory that is the pillar of the current elementary particle physics, and it is said that it can explain the characteristics such as the type and mass of elementary particles.
An international research group such as Professor Fumihiko Ukegawa of the University of Tsukuba analyzed experimental data conducted at an American research institute on elementary particles called W bosons that transmit power, and found that the mass was about 0.09% of the prediction of the standard theory. The result is that it is big.
Since the error is 0.01%, which is the highest accuracy ever analyzed, it may be necessary to revise the "Standard Model", and further verification is required.
Some researchers have published a paper that explains the existence of new elementary particles, which has caused controversy.
Professor Ukegawa, who participates in the research group, said, "I am excited that there may be something beyond the Standard Model. I think it is very important to determine what it is. I'm talking.
