13  ADLOFF 2003 limit is for the weak isotriplet spin-0 leptoquark at strong coupling $\lambda =\sqrt {4{{\mathit \pi}} }$. For the limits of leptoquarks with different quantum numbers, see their Table$~$3. Limits are derived from bounds on ${{\mathit e}^{\pm}}{{\mathit q}}$ contact interactions.
14  The bound is derived from B( ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit e}^{\pm}}{{\mathit \mu}^{\mp}}$ ) $<$ $1.7 \times 10^{-7}$.
15  CHEKANOV 2002 search for lepton-flavor violation in ${{\mathit e}}{{\mathit p}}$ collisions. See their Tables$~1 - 4$ for limits on lepton-flavor violating and four-fermion interactions induced by various leptoquarks.

19  BARATE 2000I search for deviations in cross section and jet-charge asymmetry in ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\overline{\mathit q}}}{{\mathit q}}$ due to $\mathit t$-channel exchange of a leptoquark at $\sqrt {\mathit s }$=130 to 183 GeV. Limits for other scalar and vector leptoquarks are also given in their Table$~$22.
20  BARGER 2000 explain the deviation of atomic parity violation in cesium atoms from prediction is explained by scalar leptoquark exchange.
21  GABRIELLI 2000 calculate various process with lepton flavor violation in leptoquark models.
22  ZARNECKI 2000 limit is derived from data of HERA, LEP, and Tevatron and from various low-energy data including atomic parity violation. Leptoquark coupling with electromagnetic strength is assumed.
23  ABBIENDI 1999 limits are from ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit q}}{{\overline{\mathit q}}}$ cross section at $130 - 136$, $161 - 172$, 183 GeV. See their Fig.$~$8 and Fig.$~$9 for limits in mass-coupling plane.
24  ABE 1998V quoted limit is from B( ${{\mathit B}_{{s}}}$ $\rightarrow$ ${{\mathit e}^{\pm}}{{\mathit \mu}^{\mp}}$ )$<8.2 \times 10^{-6}$. ABE 1998V also obtain a similar limit on $\mathit M_{LQ}>20.4$ TeV from B( ${{\mathit B}_{{d}}}$ $\rightarrow$ ${{\mathit e}^{\pm}}{{\mathit \mu}^{\mp}}$ )$<4.5 \times 10^{-6}$. Both bounds assume the non-canonical association of the ${{\mathit b}}~$quark with electrons or muons under SU(4).
25  ACCIARRI 1998J limit is from ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit q}}{{\overline{\mathit q}}}$ cross section at $\sqrt {\mathit s }$= $130 - 172$ GeV which can be affected by the ${{\mathit t}}-~$and ${{\mathit u}}$-channel exchanges of leptoquarks. See their Fig.$~$4 and Fig.$~$5 for limits in the mass-coupling plane.
26  ACKERSTAFF 1998V limits are from ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit q}}{{\overline{\mathit q}}}$ and ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit b}}{{\overline{\mathit b}}}$ cross sections at $\sqrt {\mathit s }$ = $130 - 172$ GeV, which can be affected by the $\mathit t$- and $\mathit u$-channel exchanges of leptoquarks. See their Fig.$~$21 and Fig.$~$22 for limits of leptoquarks in mass-coupling plane.
27  DEANDREA 1997 limit is for ${{\widetilde{\mathit R}}_{{2}}}$ leptoquark obtained from atomic parity violation (APV). The coupling of leptoquark is assumed to be electromagnetic strength. See Table$~$2 for limits of the four-fermion interactions induced by various scalar leptoquark exchange. DEANDREA 1997 combines APV limit and limits from Tevatron and HERA. See Fig.$~1 - 4$ for combined limits of leptoquark in mass-coupling plane.
28  DERRICK 1997 search for lepton-flavor violation in ${{\mathit e}}{{\mathit p}}$ collision. See their Tables$~$2--5 for limits on lepton-flavor violating four-fermion interactions induced by various leptoquarks.
29  GROSSMAN 1997 estimate the upper bounds on the branching fraction ${{\mathit B}}$ $\rightarrow$ ${{\mathit \tau}^{+}}{{\mathit \tau}^{-}}$ (X) from the absence of the ${{\mathit B}}$ decay with large missing energy. These bounds can be used to constrain leptoquark induced four-fermion interactions.
30  JADACH 1997 limit is from ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit q}}{{\overline{\mathit q}}}$ cross section at $\sqrt {\mathit s }=172.3$ GeV which can be affected by the ${{\mathit t}}$- and ${{\mathit u}}$-channel exchanges of leptoquarks. See their Fig.$~$1 for limits on vector leptoquarks in mass-coupling plane.
31  KUZNETSOV 1995B use ${{\mathit \pi}}$, ${{\mathit K}}$, ${{\mathit B}}$, ${{\mathit \tau}}$ decays and ${{\mathit \mu}}{{\mathit e}}$ conversion and give a list of bounds on the leptoquark mass and the fermion mixing matrix in the Pati-Salam model. The quoted limit is from ${{\mathit K}_{{L}}}$ $\rightarrow$ ${{\mathit \mu}}{{\mathit e}}$ decay assuming zero mixing.
32  MIZUKOSHI 1995 calculate the one-loop radiative correction to the ${{\mathit Z}}$-physics parameters in various scalar leptoquark models. See their Fig.$~$4 for the exclusion plot of third generation leptoquark models in mass-coupling plane.
33  BHATTACHARYYA 1994 limit is from one-loop radiative correction to the leptonic decay width of the ${{\mathit Z}}$. ${\mathit m}_{{{\mathit H}}}$=250 GeV, ${{\mathit \alpha}_{{s}}}({\mathit m}_{{{\mathit Z}}})=0.12$, ${\mathit m}_{{{\mathit t}}}$=180 GeV, and the electroweak strength of leptoquark coupling are assumed. For leptoquark coupled to ${{\overline{\mathit e}}_{{L}}}{{\mathit t}_{{R}}}$ , ${{\overline{\mathit \mu}}}{{\mathit t}}$ , and ${{\overline{\mathit \tau}}}{{\mathit t}}$ , see Fig.$~$2 in BHATTACHARYYA 1994B erratum and Fig.$~$3.
34  DAVIDSON 1994 gives an extensive list of the bounds on leptoquark-induced four-fermion interactions from ${{\mathit \pi}}$, ${{\mathit K}}$, ${{\mathit D}}$, ${{\mathit B}}$, ${{\mathit \mu}}$, ${{\mathit \tau}}$ decays and meson mixings, $\mathit etc$. See Table$~$15 of DAVIDSON 1994 for detail.
35  KUZNETSOV 1994 gives mixing independent bound of the Pati-Salam leptoquark from the cosmological limit on ${{\mathit \pi}^{0}}$ $\rightarrow$ ${{\overline{\mathit \nu}}}{{\mathit \nu}}$ .
36  LEURER 1994 , LEURER 1994B limits are obtained from atomic parity violation and apply to any chiral leptoquark which couples to the first generation with electromagnetic strength. For a nonchiral leptoquark, universality in ${{\mathit \pi}}_{{{\mathit \ell}}2}$ decay provides a much more stringent bound.
37  MAHANTA 1994 gives bounds of $\mathit P$- and $\mathit T$-violating scalar-leptoquark couplings from atomic and molecular experiments.
38  From ( ${{\mathit \pi}}$ $\rightarrow$ ${{\mathit e}}{{\mathit \nu}}$ )$/$( ${{\mathit \pi}}$ $\rightarrow$ ${{\mathit \mu}}{{\mathit \nu}}$ ) ratio. SHANKER 1982 assumes the leptoquark induced four-fermion coupling 4$\mathit g{}^{2}/\mathit M{}^{2}$ (${{\overline{\mathit \nu}}}_{\mathit eL}$ $\mathit u_{\mathit R}$) ( ${{\overline{\mathit d}}_{{L}}}{{\mathit e}_{{R}}}$ )with $\mathit g=0.004$ for spin-0 leptoquark and $\mathit g{}^{2}/\mathit M{}^{2}$ (${{\overline{\mathit \nu}}}_{\mathit eL}$ ${{\mathit \gamma}_{{\mu}}}{{\mathit u}_{{L}}}$ ) (${{\overline{\mathit d}}_{{R}}}$ ${{\mathit \gamma}}{}^{{{\mathit \mu}}}$ ${{\mathit e}_{{R}}}$ ) with $\mathit g≅0.6$ for spin-1 leptoquark.
