When a particle is transformed into its antiparticle and its spatial coordinates inverted, the laws of physics are required to stay the same—or so we thought. This symmetry—known as CP symmetry (charge conjugation and ...

A team of researchers from Sorbonne Université, CNRS and Ecole Normale Supérieure has reported observational evidence of a quasiparticle called an anyon. In their paper published in the journal Science, the team describes ...
The Belle II experiment has been collecting data from physical measurements for about one year. After several years of rebuilding work, both the SuperKEKB electron–positron accelerator and the Belle II detector have been ...
