Based on 20.2 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 8 TeV. ${{\mathit \Gamma}_{{t}}}$ is measured using a template fit to the reconstructed invariant mass of the ${{\mathit b}}$-jet of the semileptonically decaying top quark and the corresponding lepton, and the angular distance between ${{\mathit j}_{{b}}}$ and ${{\mathit j}_{{l}}}$ in hadronic top decay. Signal templates are generated by reweighting events at parton-level to Breit-Wigner distribution with different ${{\mathit \Gamma}_{{t}}}$ hypotheses for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV. The result is consistent with the NNLO SM prediction of 1.322 GeV.

Based on 19.7 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 8 TeV. The result is obtained by combining the measurement of ${{\mathit R}}$ = ${{\mathit \Gamma}}$( ${{\mathit t}}$ $\rightarrow$ ${{\mathit W}}{{\mathit b}}$ )/${{\mathit \Gamma}}$( ${{\mathit t}}$ $\rightarrow$ ${{\mathit W}}{{\mathit q}}$ (${{\mathit q}}={{\mathit b}},{{\mathit s}},{{\mathit d}}$)) and a previous CMS measurement of the ${{\mathit t}}$-channel single top production cross section of CHATRCHYAN 2012BQ, by using the theoretical calculation of ${{\mathit \Gamma}}$( ${{\mathit t}}$ $\rightarrow$ ${{\mathit W}}{{\mathit b}}$ ) for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV.

Based on 5.4 fb${}^{-1}$ of data in ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at 1.96 TeV. $\Gamma $( ${{\mathit t}}$ $\rightarrow$ ${{\mathit b}}{{\mathit W}}$ ) = $1.87$ ${}^{+0.44}_{-0.40}$ GeV is obtained from the observed ${{\mathit t}}$-channel single top quark production cross section, whereas B( ${{\mathit t}}$ $\rightarrow$ ${{\mathit b}}{{\mathit W}}$ ) = $0.90$ $\pm0.04$ is used assuming $\sum_{q}$B( ${{\mathit t}}$ $\rightarrow$ ${{\mathit q}}{{\mathit W}}$ ) = 1. The result is valid for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV. See the paper for the values for ${\mathit m}_{{{\mathit t}}}$ = 170 or 175 GeV.

Based on 8.7 fb${}^{-1}$ of data. The two sided 68$\%$ CL interval is 1.10 GeV $<$ ${{\mathit \Gamma}_{{t}}}$ $<$ 4.05 GeV for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV.

Based on 2.3 fb${}^{-1}$ in ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV. ABAZOV 2011B extracted ${{\mathit \Gamma}_{{t}}}$ from the partial width ${{\mathit \Gamma}}$( ${{\mathit t}}$ $\rightarrow$ ${{\mathit W}}{{\mathit b}}$ ) = $1.92$ ${}^{+0.58}_{-0.51}$ GeV measured using the ${{\mathit t}}$-channel single top production cross section, and the branching fraction br{ {{\mathit t}} \rightarrow {{\mathit W}} {{\mathit b}} } = $0.962$ ${}^{+0.068}_{-0.066}$(stat)${}^{+0.064}_{-0.052}$(syst). The ${{\mathit \Gamma}}$( ${{\mathit t}}$ $\rightarrow$ ${{\mathit W}}{{\mathit b}}$ ) measurement gives the 95$\%$ CL lowerbound of ${{\mathit \Gamma}}$( ${{\mathit t}}$ $\rightarrow$ ${{\mathit W}}{{\mathit b}}$ ) and hence that of ${{\mathit \Gamma}_{{t}}}$.

Results are based on 4.3 fb${}^{-1}$ of data in ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV. The top quark mass and the hadronically decaying ${{\mathit W}}$ boson mass are reconstructed for each candidate events and compared with templates of different top quark width. The two sided 68$\%$ CL interval is 0.3 GeV$<$ ${{\mathit \Gamma}_{{t}}}<$ 4.4 GeV for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV.

Based on 955 pb${}^{-1}$ of ${{\mathit p}}{{\overline{\mathit p}}}$ collision data at $\sqrt {s }$ = 1.96 TeV. AALTONEN 2009M selected ${{\mathit t}}{{\overline{\mathit t}}}$ candidate events for the ${{\mathit \ell}}$ + $\not E_T$ + jets channel with one or two ${{\mathit b}}$-tags, and examine the decay width dependence of the reconstructed ${\mathit m}_{{{\mathit t}}}$ distribution. The result is for ${\mathit m}_{{{\mathit t}}}$ =175 GeV, whereas the upper limit is lower for smaller ${\mathit m}_{{{\mathit t}}}$.
