Question
The DZero and CDF experiments analyzed data from a device named for this unit. For 10 points each:
[10h] Name this unit, 13.6 of which can be reached by collision energies in the LHC. This unit is the approximate rest mass energy of eight Higgs bosons or six top quarks.
ANSWER: TeV [or tera·electron·volt; accept equivalents like one trillion electron volts or 10-to-the-12 eV; reject "electronvolt" or "eV"; prompt on Tevatron]
[10m] Despite the nine TeV energy of the sphaleron, the LHC cannot sufficiently concentrate energy to observe sphalerons converting these particles into antileptons. These hadrons consist of odd numbers of quarks.
ANSWER: baryons
[10e] Sphalerons require such high energy concentration because their length scale is one percent of these baryons’ length scale. These particles contribute positive charge to atomic nuclei.
ANSWER: protons [prompt on p]
