1  AABOUD 2017D search for ${{\mathit W}}{{\mathit W}}{{\mathit j}}{{\mathit j}}$ , ${{\mathit W}}{{\mathit Z}}{{\mathit j}}{{\mathit j}}$ in ${{\mathit p}}{{\mathit p}}$ collisions at 8 TeV with 3.2 fb${}^{-1}$; set limits on anomalous couplings.
2  AABOUD 2017L search for the pair production of heavy vector-like ${{\mathit T}}$ quarks in the ${{\mathit Z}}$( $\rightarrow$ ${{\mathit \nu}}{{\mathit \nu}}$ ) ${{\mathit t}}{{\mathit X}}$ final state.
3  SIRUNYAN 2017B search for vector-like quark ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit T}}{{\mathit X}}$ $\rightarrow$ ${{\mathit t}}{{\mathit H}}{{\mathit X}}$ in 2.3 fb${}^{-1}$ at 13 TeV; no signal seen; limits placed.
4  SIRUNYAN 2017C search for vector-like quark ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit T}}{{\mathit X}}$ $\rightarrow$ ${{\mathit Z}}$ + (${{\mathit t}}$ or ${{\mathit b}}$) in 2.3 fb${}^{-1}$ at 13 TeV; no signal seen; limits placed.
5  SIRUNYAN 2017J search for ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit X}_{{5/3}}}{{\mathit X}_{{5/3}}}$ $\rightarrow$ ${{\mathit t}}{{\mathit W}}{{\mathit t}}{{\mathit W}}$ with 2.3 fb${}^{-1}$ at 13 TeV. No signal seen: m(${{\mathit X}}$) $>$ 1020 (990) GeV for RH (LH) new charge 5/3 quark.
6  AAIJ 2015BD search for production of long-lived particles in ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 7 and 8 TeV. See their Table 6 for cross section limits.
7  AAD 2013AH search for production of long-lived particles with $\vert $q$\vert =(2 - 6)\mathit e$ in ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 7 TeV with 4.4 fb${}^{-1}$. See their Fig. 8 for cross section limits.
8  AAD 2011I search for production of highly ionizing massive particles in ${{\mathit p}}{{\mathit p}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 7$~$TeV with L = 3.1 pb${}^{-1}$. See their Table 5 for similar limits for $\vert $q$\vert $ = 6${{\mathit e}}$ and 17${{\mathit e}}$, Table 6 for limits on pair production cross section.
9  AALTONEN 2009Z search for long-lived charged particles in ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 1.96 TeV with $\mathit L$ = 1.0 fb${}^{-1}$. The limits are on production cross section for a particle of mass above 100 GeV in the region $\vert {{\mathit \eta}}\vert $ ${ {}\lesssim{} }$ 0.7, $p_T>$ 40 GeV, and 0.4 $<{{\mathit \beta}}<$ 1.0.
10  Limit for weakly interacting charge-1 particle.
11  Limit for up-quark like particle.
12  ABAZOV 2009M search for pair production of long-lived charged particles in ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\mathit E_{{\mathrm {cm}}}$ = 1.96 TeV with $\mathit L$ = 1.1 fb${}^{-1}$. Limit on the cross section of ($0.31 - 0.04$) pb (95$\%$ CL) is given for the mass range of $60 - 300$ GeV, assuming the kinematics of stau pair production.
13  AKTAS 2004C look for charged particle photoproduction at HERA with mean c.m. energy of 200~GeV.
14  ABE 1992J look for pair production of unit-charged particles which leave detector before decaying. Limit shown here is for $\mathit m$=50 GeV. See their Fig.$~$5 for different charges and stronger limits for higher mass.
15  CARROLL 1978 look for neutral, $\mathit S$ = $-2$ dihyperon resonance in ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ 2 ${{\mathit K}^{+}}$ X. Cross section varies within above limits over mass range and $\mathit p_{{\mathrm {lab}}}$ = 5.1$-$5.9 ${\mathrm {GeV/}}\mathit c$.
16  LEIPUNER 1973 is an NAL 300 GeV ${{\mathit p}}$ experiment. Would have detected particles with lifetime greater than 200 ns.
