DECAMP 1990F looked for isolated charged particles, for isolated photons, and for four-jet final states. The modes ${{\mathit b}^{\,'}}$ $\rightarrow$ ${{\mathit b}}{{\mathit g}}$ for B( ${{\mathit b}^{\,'}}$ $\rightarrow$ ${{\mathit b}}{{\mathit g}}$ ) $>$ 65$\%$ ${{\mathit b}^{\,'}}$ $\rightarrow$ ${{\mathit b}}{{\mathit \gamma}}$ for B( ${{\mathit b}^{\,'}}$ $\rightarrow$ ${{\mathit b}}{{\mathit \gamma}}$ ) $>$ 5$\%$ are excluded. Charged Higgs decay were not discussed.
|
2
ABDALLAH 2007 searched for ${{\mathit b}^{\,'}}$ pair production at $\mathit E_{{\mathrm {cm}}}=196 - 209$ GeV, with 420$~$pb${}^{-1}$. No signal leads to the 95$\%$ CL upper limits on B( ${{\mathit b}^{\,'}}$ $\rightarrow$ ${{\mathit b}}{{\mathit Z}}$ ) and B( ${{\mathit b}^{\,'}}$ $\rightarrow$ ${{\mathit c}}{{\mathit W}}$ ) for ${\mathit m}_{{{\mathit b}^{\,'}}}$ = 96 to 103 GeV.
|
3
ADRIANI 1993G search for vector quarkonium states near ${{\mathit Z}}$ and give limit on quarkonium-${{\mathit Z}}$ mixing parameter $\delta <(10 - 30$) GeV${}^{2}$ (95$\%$CL) for the mass $88 - 94.5$ GeV. Using Richardson potential, a 1S ( ${{\mathit b}^{\,'}}{{\overline{\mathit b}}^{\,'}}$ ) state is excluded for the mass range $87.7 - 94.7$ GeV. This range depends on the potential choice.
|
4
ABREU 1990D assumed ${\mathit m}_{{{\mathit H}^{-}}}$ $<$ ${\mathit m}_{{{\mathit b}^{\,'}}}$ $−$ 3 GeV.
|
5
Superseded by ABREU 1991F.
|
6
AKRAWY 1990B search was restricted to data near the ${{\mathit Z}}$ peak at $\mathit E_{{\mathrm {cm}}}$ = $91.26$ GeV at LEP. The excluded region is between $23.6$ and $41.4$ GeV if no ${{\mathit H}^{+}}$ decays exist. For charged Higgs decays the excluded regions are between (${\mathit m}_{{{\mathit H}^{+}}}$ $+1.5$ GeV) and $45.5$ GeV.
|
7
AKRAWY 1990J search for isolated photons in hadronic ${{\mathit Z}}$ decay and derive B( ${{\mathit Z}}$ $\rightarrow$ ${{\mathit b}^{\,'}}{{\overline{\mathit b}}^{\,'}}$ )$\cdot{}$B( ${{\mathit b}^{\,'}}$ $\rightarrow$ ${{\mathit \gamma}}$ X)/B( ${{\mathit Z}}$ $\rightarrow$ hadrons) $<$ $2.2 \times 10^{-3}$. Mass limit assumes B( ${{\mathit b}^{\,'}}$ $\rightarrow$ ${{\mathit \gamma}}$ X) $>$ 10$\%$.
|
8
ABE 1989E search at $\mathit E_{{\mathrm {cm}}}$ = 56$-$57 GeV at TRISTAN for multihadron events with a spherical shape (using thrust and acoplanarity) or containing isolated leptons.
|
9
ABE 1989G search was at $\mathit E_{{\mathrm {cm}}}$ = 55$-60.8$ GeV at TRISTAN.
|
10
If the photonic decay mode is large (B( ${{\mathit b}^{\,'}}$ $\rightarrow$ ${{\mathit b}}{{\mathit \gamma}}$ ) $>$ 25$\%$), the ABRAMS 1989C limit is $45.4$ GeV. The limit for for Higgs decay ( ${{\mathit b}^{\,'}}$ $\rightarrow$ ${{\mathit c}}{{\mathit H}^{-}}$ , ${{\mathit H}^{-}}$ $\rightarrow$ ${{\overline{\mathit c}}}{{\mathit s}}$ ) is $45.2$ GeV.
|
11
ADACHI 1989C search was at $\mathit E_{{\mathrm {cm}}}$ = $56.5-60.8$ GeV at TRISTAN using multi-hadron events accompanying muons.
|
12
ADACHI 1989C also gives limits for any mixture of ${{\mathit C}}{{\mathit C}}$ and ${{\mathit b}}{{\mathit g}}$ decays.
|
13
ENO 1989 search at $\mathit E_{{\mathrm {cm}}}$ = 50$-60.8$ at TRISTAN.
|
14
ENO 1989 considers arbitrary mixture of the charged current, ${{\mathit b}}{{\mathit g}}$ , and ${{\mathit b}}{{\mathit \gamma}}$ decays.
|
15
IGARASHI 1988 searches for leptons in low-thrust events and gives $\Delta \mathit R({{\mathit b}^{\,'}}$) $<$ $0.26$ (95$\%$ CL) assuming charged current decay, which translates to ${\mathit m}_{{{\mathit b}^{\,'}}}$ $>$ $24.4$ GeV.
|
16
SAGAWA 1988 set limit ${\mathit \sigma (}$top${)}$ $<$ 6.1 pb at CL=95$\%$ for top-flavored hadron production from event shape analyses at $\mathit E_{{\mathrm {cm}}}$ = 52 GeV. By using the quark parton model cross-section formula near threshold, the above limit leads to lower mass bounds of 23.8 GeV for charge $−$1/3 quarks.
|
17
ADEVA 1986 give 95$\%$CL upper bound on an excess of the normalized cross section, $\Delta \mathit R$, as a function of the minimum c.m. energy (see their figure 3). Production of a pair of 1/3 charge quarks is excluded up to $\mathit E_{{\mathrm {cm}}}$ = 45.4 GeV.
|
18
ALTHOFF 1984C narrow state search sets limit $\Gamma\mathrm {( {{\mathit e}^{+}} {{\mathit e}^{-}} )}{}$B(hadrons) $<$2.4 keV CL = 95$\%$ and heavy charge 1/3 quark pair production $\mathit m$ $>$21 GeV, CL = 95$\%$.
|
19
ALTHOFF 1984I exclude heavy quark pair production for 7 $<\mathit m$ $<$19 GeV (1/3 charge) using aplanarity distributions (CL = 95$\%$).
