1  AAD 2024AT search for ${{\mathit h}}$ $\rightarrow$ ALPs with ALP $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}$. No signal observed. Limits placed in BF(${{\mathit h}}$) vs. m(ALP) plane.
2  ALBERT 2018C search for WIMP annihilation in Sun to long-lived, radiatively decaying mediator; no signal; limits set on $\sigma {}^{SD}({{\mathit \chi}}{{\mathit p}}$) assuming long-lived mediator.
3  KHACHATRYAN 2017D search for new scalar resonance decaying to ${{\mathit Z}}{{\mathit \gamma}}$ with ${{\mathit Z}}$ $\rightarrow$ ${{\mathit e}^{+}}{{\mathit e}^{-}}$ , ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ in ${{\mathit p}}{{\mathit p}}$ collisions at 8 and 13 TeV; no signal seen.
4  AAD 2016AI search for excited quarks (EQ) and quantum black holes (QBH) in 3.2 fb${}^{-1}$ at 13 TeV of data; exclude EQ below 4.4 TeV and QBH below 3.8 (6.2) TeV for RS1 (ADD) models. The visible cross section limit was obtained for 5 TeV resonance with ${{\mathit \sigma}_{{{G}}}}/{{\mathit M}_{{{G}}}}$ = 2$\%$.
5  KHACHATRYAN 2016M search for ${{\mathit \gamma}}{{\mathit \gamma}}$ resonance using 19.7 fb${}^{-1}$ at 8 TeV and 3.3 fb${}^{-1}$ at 13 Tev; slight excess at 750 GeV noted; limit set on RS graviton.
6  ABBIENDI 2000D associated production limit is for ${\mathit m}_{{{\mathit X}^{0}}}$= $90 - 188$ GeV, ${\mathit m}_{{{\mathit Y}^{0}}}$=0 at $\mathit E_{{\mathrm {cm}}}$=189 GeV. See also their Fig.$~$9.
7  ABBIENDI 2000D pair production limit is for ${\mathit m}_{{{\mathit X}^{0}}}$ = $45 - 94$ GeV, ${\mathit m}_{{{\mathit Y}^{0}}}$=0 at $\mathit E_{{\mathrm {cm}}}$=189 GeV. See also their Fig.$~$12.
8  ACKERSTAFF 1997B associated production limit is for ${\mathit m}_{{{\mathit X}^{0}}}$ = $80 - 160$ GeV, ${\mathit m}_{{{\mathit Y}^{0}}}$=0 from $10.0~$pb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 161 GeV. See their Fig.$~$3(a).
9  ACKERSTAFF 1997B pair production limit is for ${\mathit m}_{{{\mathit X}^{0}}}$ = $40 - 80$ GeV, ${\mathit m}_{{{\mathit Y}^{0}}}$=0 from $10.0~$pb${}^{-1}$ at $\mathit E_{{\mathrm {cm}}}$ = 161 GeV. See their Fig.$~$3(b).
