Question
A false detection of the meson consisting of this particle and its antiparticle was named for a pun on the name of its discoverer, Leon Lederman. For 10 points each:
[10h] Name this particle of matter found in the upsilon meson. Kobayashi and Maskawa’s CKM matrix implies the existence of this negatively charged particle in order to explain CP violation.
ANSWER: bottom quarks [or beauty quarks or b quarks] (The erroneously detected particle was dubbed the “Oops-Leon.”)
[10m] In 2019, ALICE detected low elliptic flow from upsilon mesons in a type of plasma named for quarks and these particles. These particles and quarks carry color charge.
ANSWER: gluons [prompt on g; accept quark–gluon plasma]
[10e] ALICE is an experiment at this collider. The Higgs boson was discovered by this main collider at CERN (“sern”).
ANSWER: Large Hadron Collider [or LHC]
