bottomonium造句

• In 2008, BaBar physicists detected the lowest energy particle in the bottomonium quark family.
• During his spokesmanship of the BaBar Collaboration, the accelerator detected and measured the lowest energy state of the bottomonium quark family ( ?b ).
• The true analogs of positronium in the theory of strong interactions are the quarkonium states : they are mesons made of a heavy quark and antiquark ( namely, charmonium and bottomonium ).
• At the high LHC collision energy, both the charmonium states ( J / ? and ?2 ) as well as the bottomonium states ( ?, ?2 and ?2 2 ) can be studied.
• Today there is a large amount of data available from RHIC and LHC on charmonium and bottomonium suppression and ALICE tries to distinguish between effects due to the formation of the QGP and those from cold nuclear matter effects.
• Good agreement with the bottomonium masses has been found, and this provides one of the best non-perturbative tests of LQCD . For charmonium masses the agreement is not as good, but the LQCD community is actively working on improving their techniques.
