[1] A discussion of the definition of the top quark mass in these measurements can be found in the review ``The Top Quark.''
[2] Based on published top mass measurements using data from Tevatron Run-I and Run-II and LHC at $\sqrt {s }$ = 7 TeV. Including the most recent unpublished results from Tevatron Run-II, the Tevatron Electroweak Working Group reports a top mass of $173.2$ $\pm0.9$ GeV. See the note ``The Top Quark' in the Quark Particle Listings of this $\mathit Review$.
[3] This value is $\Gamma\mathrm {({{\mathit t}} \rightarrow {{\mathit W}} {{\mathit b}})}/\Gamma\mathrm {({{\mathit t}} \rightarrow {{\mathit W}} {{\mathit q}})}$.
[4] This limit is for $\Gamma\mathrm {({{\mathit t}} \rightarrow {{\mathit \gamma}} {{\mathit q}})}/\Gamma\mathrm {({{\mathit t}} \rightarrow {{\mathit W}} {{\mathit b}})}$.
[5] This limit is for $\Gamma\mathrm {({{\mathit t}} \rightarrow {{\mathit Z}} {{\mathit q}})}/\Gamma\mathrm {({{\mathit t}} \rightarrow {{\mathit W}} {{\mathit b}})}$.
