Abstract

As demonstrated in the previous chapter, valuable insights can be gained from the measurement of absolute cross sections. However, they are subject to the totality of experimental and theoretical uncertainties. Therefore, it is worthwhile to contemplate alternative observables that are either insensitive or sensitive at a reduced level to the dominant sources of uncertainty. The possibility discussed in this chapter deals with cross section ratios.

Notes

  1. 1.

    ATLAS additionally investigated the quantity \(N_\mathrm {32}\), which in contrast to \(R_\mathrm {32}\), receives not only a single entry per event, but one entry per jet in each event.

  2. 2.

    2.76 TeV is the baseline \(pp\) centre-of-mass energy for comparisons with heavy-ion (\(PbPb\)) collisions at the LHC with 2.76 TeV of energy per nucleon-nucleon pair.
