An international team of scientists that operate the BESIII Experiment at the Beijing Electron Positron Collider in China recently began a series of specialized studies aiming at an understanding of the anomalous'Y(4260)'particle.As a striking and unexpected first observation from these new studies,the collaboration has reported that the Y(4260)particle in fact decays to a new,and perhaps even more mysterious,particle that they named the'Z c(3900).'
An international team of scientists that operate the BESIII Experiment at the Beijing Electron Positron Collider in China recently began a series of specialized studies aiming at an understanding of the anomalous ＂Y（4260）＂ particle. As a striking and unexpected first observation from these new studies, the collaboration has reported that the Y（4260） particle in fact decays to a new, and perhaps even more mysterious, particle that they named the ＂Zc（3900）.＂
