1  ABRAMOWICZ 2019 limits are from Q${}^{2}$ spectrum measurements of ${{\mathit e}^{\pm}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit e}^{\pm}}{{\mathit X}}$ .
2  SIRUNYAN 2019AC limits are from ${{\mathit e}^{+}}{{\mathit e}^{-}}$ mass distribution in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV.
3  AABOUD 2017AT limits are from ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV. The quoted limit uses a uniform positive prior in 1/${{\mathit \Lambda}^{2}}$.
4  ABDALLAH 2009 and SCHAEL 2007A limits are from $\mathit R_{b}$, $\mathit A{}^{b}_{FB}$.
5  SCHAEL 2007A limits are from $\mathit R_{c}$, $\mathit Q{}^{depl}_{FB}$, and hadronic cross section measurements.
6  CHEUNG 2001B is an update of BARGER 1998E.
7  AABOUD 2016U limits are from ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV. The quoted limit uses a uniform positive prior in 1/${{\mathit \Lambda}^{2}}$.
8  KHACHATRYAN 2015AE limit is from ${{\mathit e}^{+}}{{\mathit e}^{-}}$ mass distribution in ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 8 TeV.
9  AAD 2014BE limits are from ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV. The quoted limit uses a uniform positive prior in 1/${{\mathit \Lambda}^{2}}$.
10  AAD 2013E limis are from ${{\mathit e}^{+}}{{\mathit e}^{-}}$ mass distribution in ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 7 TeV.
11  AAD 2012AB limis are from ${{\mathit e}^{+}}{{\mathit e}^{-}}$ mass distribution in ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 7 TeV.
12  AARON 2011C limits are from ${{\mathit Q}^{2}}$ spectrum measurements of ${{\mathit e}^{\pm}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit e}^{\pm}}{{\mathit X}}$ .
13  ABDALLAH 2011 limit is from ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit t}}{{\overline{\mathit c}}}$ cross section. ${{\mathit \Lambda}_{{LL}}}$ = ${{\mathit \Lambda}_{{LR}}}$ = ${{\mathit \Lambda}_{{RL}}}$ = ${{\mathit \Lambda}_{{RR}}}$ is assumed.
14  SCHAEL 2007A limit assumes quark flavor universality of the contact interactions.
15  ABULENCIA 2006L limits are from ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV.
