Combinations of the CMS alternative technique measurements of the top quark mass

A new combination of the CMS top quark mass measurements is presented. The combination uses the measurements that were not included in the published CMS Run I result. The measurements use alternative analysis techniques, and the combination is used to cross check the published result for $m_{t}$. The combination gives a result of $m_{\rm t} = 172.58 \pm 0.21 \text{ (stat.)} \pm 0.72 \text{ (syst.)}~\mathrm{GeV}$ with a precision of $0.4\%$, which is in very good agreement with the published CMS Run I combination. While slightly less precise, this study provides an independent verification of the published result. It also provides some pointers towards possible improvements with the data from Run II. When combined with the published measurements, a result of $172.43 \pm 0.13 \text{ (stat.)} \pm 0.46 \text{ (syst.)}~\mathrm{GeV}$ for $m_{\rm t}$ is obtained. This is essentially the same as the published value, indicating that the new results are strongly correlated with the published measurements, and/or have not yet reached the precision needed to improve the published result.
