5) The B mesons can now be assured of a place in the tables of known subatomic particles.6) CLEO initially measured the properties of the Υ(1–3S) resonances below the threshold for producing B mesons.
7) From the 18 possible B mesons they were able to find, the researchers have deduced a mass of 5270 MeV for the neutral B meson and 5270 MeV for the charged B - some 5.3 times as heavy as the proton.

9) In such cases the spray of particles emanating from the electron-positron collision would be entirely consistent with the steps expected for the decay of a B meson (see Figure).
10) The K mesons live long enough to produce tracks in the CLEO detector, so the team could work back from detected K mesons to hunt for those that seemed likely to have originated from a B meson.
11) CESR is the only machine that can produce reasonably large numbers of the heaviest upsilon, so its collisions between electrons and positrons provide the most promising hunting ground for B mesons.
12) The B mesons, however, contain only one B quark (or antiquark) bound instead to a more 'ordinary' u or d antiquark (or quark).
13) Physicists working on CESR, the Cornell Electron Storage Ring at Cornell University in Ithaca, New York, have found new evidence for the so-called B mesons.
14) In the BaBar experiment (2007) it was searched for sidereal variations during Earth's rotation using B mesons (thus bottom quarks) and their antiparticles.

15) An excess of electrons and muons at the Υ(4S) demonstrated the existence of weak decays and confirmed the interpretation of the Υ(4S) decaying to B mesons.16) The Υ(4S) was discovered shortly after by CLEO and CUSB and was interpreted as decaying to B mesons because of its large decay width.
17) Although CLEO ran mainly near the Υ(4S) to study B mesons, it was also competitive with experiments designed to study charm hadrons.
18) The program began by revisiting the Υ states below the B meson threshold and the last data collected with the CLEO-III detector was at the Υ(1-3S) resonances.
19) With the advent of the high luminosity BaBar and Belle experiments, CLEO could no longer make competitive measurements of most of the properties of the B mesons.
20) During the CLEO II era, the collaboration oBserved the flavor changing neutral current decays B+,0→ K+,0 γ and B → s γ. Decays of B mesons to two charmless mesons were also discovered during CLEO II.
21) Furthermore, the presence of an excess of electrons and muons at the Υ(4S) indicated that it decayed to B mesons.
22) When the BaBar and Belle B factories began to collect large amounts of data in the early 2000s, CLEO was no longer able to make competitive measurements of B mesons.
23) While CLEO was studying the B mesons, it was also able to measure the properties of D mesons and tau leptons, and discover many new charm hadrons.
24) Once the CUSB experiment was discontinued in the late 1980s, CLEO then spent most of its time at the Υ(4S) and measured many important properties of the B mesons.
25) Increasing amounts of accelerator time were spent at the Υ(4S) as the collaboration became more interested in the study of B mesons.
26) The detector underwent five major upgrades over the course of its thirty-year lifetime, both to upgrade the capabilities of the detector and to optimize it for the study of B mesons.
27) The fourth Υ resonance, the Υ(4S), was slightly above the threshold for, and therefore ideal for the study of, B meson production.
28) On 8 November 2012, the LHCB team reported on an experiment seen as a "golden" test of supersymmetry theories in physics, by measuring the very rare decay of the Bs meson into two muons (Bs0 → μ+μ−).
