Physicists in the ALICE (A Large Ion Collider Experiment) Collaboration at CERN have announced the first measurements of an elliptic-shaped flow of upsilons, bottomonium particles consisting of a bottom quark and its antiquark. Bottomonia and their charm-quark counterparts, charmonium particles, are excellent probes of the quark-gluon plasma, a state of matter thought to have formed [...]... SCI-NEWS.COM · 4 weeks
