Abstract: Neutral-current four-fermion production, e + e − → f f ¯ f ′ f ¯ ′ , is studied in 0.7 fb −1 of data collected with the L3 detector at LEP at centre-of-mass energies s = 183 – 209 GeV . Four final states are considered: q q ¯ ν ν ¯ , q q ¯ l + l − , l + l − l ′ + l ′ − and l + l − ν ν ¯ , where l denotes either an electron or a muon. Their cross sections are measured and found to agree with the Standard Model predictions. In addition, the e + e − → Z γ ∗ → f f ¯ f ′ f ¯ ′ process is studied and its total cross section at the average centre-of-mass energy 〈 s 〉 = 196.6 GeV is found to be 0.29 ± 0.05 ± 0.03 pb , where the first uncertainty is statistical and the second systematic, in agreement with the Standard Model prediction of 0.22 pb. Finally, the mass spectra of the q q ¯ l + l − final states are analysed to search for the possible production of a new neutral heavy particle, for which no evidence is found.

Abstract: The process e+e-→Zγ where the Z boson decays into hadrons or neutrinos, is studied with data collected with the L3 detector at LEP at centre-of-mass energies from 189 up to 209 GeV. The cross sections are measured and found to be in agreement with the Standard Model predictions. Limits on triple neutral-gauge-boson couplings, forbidden in the Standard Model at tree level, are derived. Limits on the energy scales at which the anomalous couplings could be manifest are set. They range from 0.3 to 2.3 TeV depending on the new physics effect under consideration. © 2004 Published by Elsevier B.V.

Abstract: The cross section of the process e + e − → Z γ γ → q q ¯ γ γ is measured with 215 pb−1 of data collected with the L3 detector during the final LEP run at centre-of-mass energies around 205 GeV and 207 GeV. No deviation from the Standard Model expectation is observed. The full data sample of 713 pb−1, collected above the Z resonance, is used to constrain the coefficients of anomalous quartic gauge boson couplings to: − 0.02 GeV − 2 a 0 / Λ 2 0.03 GeV − 2 , − 0.07 GeV − 2 a c / Λ 2 0.05 GeV − 2 , at 95% confidence level.

Abstract: Results are presented from a study of the structure of high energy hadronic events recorded by the L3 detector at s ⩾192 GeV. The distributions of several event shape variables are compared to resummed O (α s 2 ) QCD calculations. We determine the strong coupling constant at three average centre-of-mass energies: 194.4, 200.2 and 206.2 GeV. These measurements, combined with previous L3 measurements at lower energies, demonstrate the running of α s as expected in QCD and yield α s ( m Z )=0.1227±0.0012±0.0058, where the first uncertainty is experimental and the second is theoretical.

Abstract: The process e + e − → Z γγ→ q q γγ is studied in 0.5 fb−1 of data collected with the L3 detector at centre-of-mass energies between 130.1 GeV and 201.7 GeV. Cross sections are measured and found to be consistent with the Standard Model expectations. The study of the least energetic photon constrains the quartic gauge boson couplings to −0.008 GeV−2

Abstract: Excited leptons are searched for using the L3 detector at LEP. The data collected at centre-of-mass energies in the range from 192 up to 202 GeV correspond to a total luminosity of 233 pb−1. No evidence of either pair production of excited leptons, nor of single production is found. From the searches for pair produced excited leptons, lower mass limits close to the kinematic limit are set. From the searches for singly produced excited leptons, upper limits on their couplings are derived in the mass range up to 200 GeV.

Abstract: The cross section for the production of Z boson pairs is measured using the data collected by the L3 detector at LEP in 1999 in e^+e^- collisions at centre-of-mass energies ranging from 192 GeV up to 202 GeV. Events in all the visible final states are selected, measuring the cross section of this process. The special case of final states containing b quarks is also investigated. All results are in agreement with the Standard Model predictions.

Abstract: In a search for the Standard Model Higgs boson, carried out on 212.5~$\mathrm{pb^{-1}}$ of data collected by the L3 detector at the highest LEP centre-of-mass energies, including 116.5~$\mathrm{pb^{-1}}$ above $\sqrt{s} = 206$~GeV, an excess of candidates for the process $e^+ e^- \rightarrow Z^{*}\rightarrow HZ$ is found for Higgs masses near 114.5~GeV. We present an analysis of our data and the characteristics of our strongest candidates.

Abstract: We investigate Bose-Einstein correlations (BEC) in W-pair production at √s ≃ 189 GeV using the L3 detector at LEP. We observe BEC between particles from a single W decay in good agreement with those from a light-quark Z decay sample. We investigate their possible existence between particles coming from different W's. No evidence for such inter-W BEC is found. (C) 2000 Elsevier Science B.V.

Abstract: Single W boson production in electron-positron collisions is studied with the L3 detector at LEP. The data sample collected at a centre-of-mass energy of $\sqrt{s} = 188.7 \mathrm{\ Ge\kern -0.1em V}{}$ corresponds to an integrated luminosity of $176.4\,\mbox{pb$^{-1}$}$. Events with a single energetic lepton or two acoplanar hadronic jets are selected. Within phase-space cuts, the total cross-section is measured to be $0.53 \pm 0.12 \pm 0.03 \ \rm{pb}$, consistent with the Standard Model expectation. Including our single W boson results obtained at lower $\sqrt{s}$, the WW$\gamma$ gauge couplings $\kappa_\gamma$ and $\lambda_\gamma$ are determined to be \mbox{$\kappa_\gamma = 0.93 \pm 0.16 \pm 0.09$} and \mbox{$\lambda_\gamma = -0.31^{+0.68}_{-0.19} \pm 0.13$}.

Abstract: We report on measurements of the inclusive production rate of Σ+ and Σ0 baryons in hadronic Z decays collected with the L3 detector at LEP. The Σ+ baryons are detected through the decay Σ+→pπ0, while the Σ0 baryons are detected via the decay mode Σ0→Λγ. The average numbers of Σ+ and Σ0 per hadronic Z decay are measured to be: NΣ++NΣ̄+=0.114±0.011stat±0.009syst NΣ0+NΣ̄0=0.095±0.015stat±0.013syst. These rates are found to be higher than the predictions from Monte Carlo hadronization models and analytical parameterizations of strange baryon production., Facultad de Ciencias Exactas

Abstract: A search for excited leptons, e ∗ , μ ∗ , τ ∗ , ν e ∗ , ν μ ∗ and ν τ ∗ , was performed with the L3 detector at LEP using data collected at a centre-of-mass energy of 189 GeV, corresponding to an integrated luminosity of 176 pb −1 . No evidence of their production is observed. From the searches for pair produced excited leptons, lower mass limits are set close to the kinematic limit. From the searches for singly produced excited leptons, upper limits on their couplings are derived in the mass range up to 189 GeV.

Abstract: Single and multi-photon events with missing energy are analysed using data collected with the L3 detector at LEP at a centre-of-mass energy of 189 GeV, for a total of 176 pb-1 of integrated luminosity. The cross section of the process e+e- → νν̄γ(γ) is measured and the number of light neutrino flavours is determined to be Nv = 3.011±0.077 including lower energy data. Upper limits on cross sections of supersymmetric processes are set and interpretations in supersymmetric models provide improved limits on the masses of the lightest neutralino and the gravitino. Graviton-photon production in low scale gravity models with extra dimensions is searched for and limits on the energy scale of the model are set exceeding 1 TeV for two extra dimensions., Facultad de Ciencias Exactas

Abstract: We report the result of a search for scalar leptons in $\rm e^+e^-$, collisions at 189 GeV centre-of-mass energy at LEP. No evidence for such particles is found in a data sample of 176 pb$^{-1}$. Improved upper limits are set on the production cross sections for these new particles. New exclusion contours in the parameter space of the Minimal Supersymmetric Standard Model are derived, as well as new lower limits on the masses of these supersymmetric particles. Under the assumptions of common gaugino and scalar masses at the GUT scale, we set an absolute lower limit on the mass of the lightest scalar electron of 65.5 GeV.

Abstract: Searches for scalar top and scalar bottom quarks, as well as for mass-degenerate scalar quarks of the first two families are performed at 189 GeV centre-of-mass energy with the L3 detector at LEP. No signals are observed. Model-independent limits on the scalar top production cross sections are determined for the decay modes $\rm \tilde{t}_1 \rightarrow c \tilde{\chi}_1^0$ and $\rm \tilde{t}_1 \rightarrow b \ell \tilde{\nu}$. For scalar quarks of the other flavours $\tilde{\mathrm{q}} \to \mathrm{q} \tilde{\chi}_1^0$ decays are considered. Within the framework of the Minimal Supersymmetric Standard Model mass limits are set at 95\% C.L. for these particles. Indirect limits on the gluino mass are also derived.

Abstract: The pair production of Z bosons is studied using the data collected by the L3 detector at LEP in 1998 in $\rm e^+e^-$ collisions at a centre--of--mass energy of 189\,GeV. All the visible final states are considered and the cross section of this process is measured to be $0.74^{+0.15}_{-0.14}\,{(\rm stat.)}\,{\pm 0.04}\,{(\rm syst.)}\, \mathrm{pb}$. Final states containing b quarks are enhanced by a dedicated selection and their production cross section is found to be $0.18^{+0.09}_{-0.07}\,{(\rm stat.)}\,\pm 0.02\,{\rm (syst.)}\, \mathrm{pb}$. Both results are in agreement with the Standard Model predictions. Limits on anomalous couplings between neutral gauge bosons are derived from these measurements

Abstract: A search for pair-produced charged Higgs bosons is performed with the L3 detector at LEP using data collected at a centre-of-mass energy of 188.6 GeV, corresponding to an integrated luminosity of 176.4 pb −1 . Higgs decays into a charm and a strange quark or into a tau lepton and its associated neutrino are considered. The observed events are consistent with the expectations from Standard Model background processes. A lower limit of 65.5 GeV on the charged Higgs mass is derived at 95% confidence level, independent of the decay branching ratio Br(H ± →τν).

Abstract: A search for the Standard Model Higgs boson is carried out on $176.4\ \mathrm{pb}^{-1}$ of data collected by the L3 detector at a center-of-mass energy of $189 \mathrm{\ Ge\kern -0.1em V}$. The data are consistent with the expectations of Standard Model processes and no evidence of a Higgs signal is observed. Combining the results of this search with those at lower center-of-mass energies, a lower limit on the mass of the Standard Model Higgs boson of $95.3\mathrm{\ Ge\kern -0.1em V}$ is set at the 95\% confidence level.

Abstract: We report the result of a search for scalar leptons in e+e−collisions at 183 GeV centre-of-mass energy at LEP. No evidence for such particles is found in a data sample of 55.2 pb−1. Improved upper limits are set on the production cross-sections for stable as well as unstable scalar leptons. New exclusion contours in the parameter space of the Minimal Supersymmetric Standard Model are derived, as well as new lower limits on scalar lepton masses.

Abstract: The time-integrated $\mathrm{B}^{0}\bar{\mathrm{B}}^{0}$ mixing parameter and the forward-backward charge asymmetry in the process $\mathrm{e}^{+}\mathrm{e}^{-} \rightarrow \mathrm{b}\bar{\mathrm{b}}$ are measured in hadronic \Z events containing prompt muons or electrons, collected by the L3 experiment in the years 1990 to 1995. The total sample of 3.3 million hadronic $\mathrm{Z}$ events with a mean centre-of-mass energy of 91.26 GeV yields: \begin{eqnarray*} \mbox{$A_{\mathrm{FB}}^{\mathrm{b} }$} & = & 0.0960 \pm 0.0066(stat.) \pm 0.0033(sys.) \,, \\ %corel-6 \mbox{$\chi_{\mathrm{b}}$} & = & 0.1192 \pm 0.0068(stat.) \pm 0.0051(sys.) \,. % \end{eqnarray*} %%% %%% %%% %%% This asymmetry measurement together with measurements at energies away from the $\mathrm{Z}$ pole energy yield a pole asymmetry and corresponding effective electroweak mixing angle of: \begin{eqnarray*} \mbox{$A_{\mathrm{FB}}^{0,\mathrm{b}}$} & = & 0.1015 \pm 0.0064(stat.) \pm 0.0035(sys.) \,, \\ %corel-6.nb \mbox{$\sin^{2}\bar{\theta}_{\mathrm{W}}$} & = & 0.2318 \pm 0.0013 \, .\\ %sin2tw-3.nb \end{eqnarray*}

Abstract: We report on a study of single W boson production in a data sample collected by the L3 detector at centre-of-mass energies from 130 to 183 GeV. The signal consists of large missing energy final states with a single energetic lepton or two hadronic jets. The measured cross sections at five different centre-of-mass energies are consistent with the Standard Model expectations. The following limits on the anomalous WW γ gauge couplings are derived at 95% CL: −0.46 Δκ γ λ γ

Abstract: A search for single and multi-photon events with missing energy is performed using data collected at centre-of-mass energies between 161 GeV and 172 GeV for a total of 20.9 pb$^{-1}$ of integrated luminosity. The results obtained are used to derive the value for the $\nu\bar{\nu}\gamma(\gamma)$ cross section as well as upper limits on new physics processes.

Abstract: We have studied the process $e^+e^-{\rightarrow}\rm n {\gamma}$ $(\rm n{\ge}2)$ at centre-of-mass energies of 161.3 GeV and 172.1 GeV. The analysis is based on a sample of events collected by the L3 detector in 1996 corresponding to total integrated luminosities of 10.7 ${\rm pb^{-1}}$ and 10.1 ${\rm pb^{-1}}$ respectively. The observed rates of events with two and more photons and the characteristic distributions are in good agreement with the Standard Model expectations. This is used to set lower limits on contact interaction energy scale parameters, on the QED cut-off parameters and on the mass of excited electrons.

Abstract: A search for unstable neutral and charged heavy leptons as well as for stable charged heavy leptons has been made at center-of-mass energies s = 161 GeV and s 172 GeV with the L3 detector at LEP. No evidence for their existence was found. We exclude unstable neutral leptons of Dirac (Majorana) type for masses below 78.0 (66.7), 78.0 (66.7) and 72.2 (58.2) GeV, if the heavy neutrino couples to the electron, muon or tau family, respectively. We exclude unstable charged heavy leptons for masses below 81.0 GeV for a wide mass range of the associated neutral heavy lepton. The production of stable charged heavy leptons with a mass less than 84.2 GeV is also excluded. If the unstable charged heavy lepton decays via mixing into a massless neutrino, we exclude masses below 78.7 GeV.

Abstract: We report on measurements of $\mathrm{e^+e^-}$ annihilation into hadrons and lepton pairs. The data have been taken with the L3 detector at LEP at centre--of--mass energies between 161~$\mathrm{Ge\kern -0.12em V}$ and 172~$\mathrm{Ge\kern -0.12em V}$. In a data sample corresponding to 21.2~pb$^{-1}$ of integrated luminosity 2728 hadronic and 868 lepton--pair events are selected. The measured cross sections and leptonic forward--backward asymmetries agree well with the Standard Model predictions. \end{abstract}

Abstract: We present a study of the structure of hadronic events recorded by the L3 detector at LEP at the center of mass energies of 161 and 172 GeV. The data sample corresponds to an integrated luminosity of 21.25 pb-1 collected during the high energy runs of 1996. The distributions of event shape variables and the energy dependence of their mean values are well reproduced by QCD models. From a comparison of the data with resummed second order QCD calculations, we determine the strong coupling constant at the two energies. Combining with our earlier measurements we find that the strong coupling constant decreases with increasing energy as expected in QCD.

Abstract: A search for excited leptons $\rm e^*,~\mu^*, ~\tau^*$ and $\nu_{\rm e}^*$ in $\rm e^+e^-$ collisions at $\rm \sqrt{s}$ = 161 GeV is performed using the $\rm 10.8 ~pb^{-1}$ of data collected by the L3 detector at LEP. No evidence has been found for their existence. From an analysis of the expected $\ell^*\ell^*$ pair production in the channels $\rm ee\gamma\gamma$, $\rm \mu\mu\gamma\gamma$, $\rm \tau\tau\gamma\gamma$, $\rm eeWW$, and $\rm \nu\nu\gamma\gamma$, the lower mass limits at 95\% C.L. are 79.7 GeV for $\rm e^{*}$, 79.9 GeV for $\mu^{*}$, 79.3 GeV for $\tau^{*}$ and 71.3 GeV for $\nu_{\rm e}^{*}$ assuming the same couplings as for standard leptons. From an analysis of the expected $\ell\ell^*$ single production in channels $\rm ee\gamma$, $\mu\mu\gamma$, $ \tau\tau\gamma$, $\rm \nu_{e}eW$ and $\nu\nu\gamma$, the upper limits on the couplings $\lambda/m_{\ell^*}$ up to $m_{\ell^{*}}$ = 161 GeV are determined.

Abstract: Using a data sample of 1 475 000 Z → qq(γ) events collected during 1994 with the L3 detector at LEP, we have studied the purely leptonic decays of heavy flavour mesons, D s − → τ − ν τ and B − → τ − ν τ . A signal is observed in the invariant mass distribution M(γD s − ) corresponding to the decay sequence D ∗− → γD s − , D s − → τ − ν τ , τ − → l − ν l ν τ . The branching fraction for D s − → τ − ν τ decays is measured to be β (D s − → τ − ν τ ) = 0.074 ± 0.028(stat) ± 0.016(syst) ± 0.018(norm) . No signal of B − → τ − ν τ decays is observed in the data, corresponding to an upper limit on the branching franction β( B − → τ − ν τ ) −4 at 90% CL.

Abstract: We have studied the process e+e− → nγ (n ≥ 2) at an average center-of-mass energy of 133 GeV using the L3 detector at LEP. For an integrated luminosity of 4.95 pb−1 we find one γγγγ(γ) final state with only hard photons. The rates of both γγγ and γγ events are consistent with QED expectations. The cross section of the reaction e+e− → γγ(γ) in the polar range 16° < θγ < 164° is measured to be 22.6 ± 2.2 pb. Decays into photons of narrow scalar resonances with masses between 90 and 130 GeV are not observed. The observation of the event with four energetic photons is consistent with QED although the kinematic configuration of the photons is atypical.

Abstract: A search for unstable sequential neutral and charged heavy leptons has been made at center-of-mass energies 130 and 136 GeV with the L3 detector at LEP. The neutral leptons are assumed to decay via mixing to electrons and muons. No evidence for their existence was found. We exclude unstable Dirac neutrinos for masses below 59.3 (57.9) GeV and unstable Majorana neutrinos below 48.6 (47.2) GeV if the neutrino couples to the electron(muon) family. We exclude unstable charged heavy leptons for masses below 61 GeV for a wide range of the associated neutral lepton mass.

Abstract: A search for supersymmetric particles (charginos, neutralinos, sleptons and stop quarks) has been performed with data collected by the L3 detector during the November 1995 run of the LEP collider at centre of mass energies between 130 and 140 GeV with a total integrated luminosity of 5.1 pb−1. We observe no signal for supersymmetric particles and we set improved exclusion limits on their production cross sections and masses.

Abstract: Using the data recorded with the L3 detector at LEP, we study the process e + e − → μ + μ − ( γ ) for events with hard initial-state photon radiation. The effective centre-of-mass energies of the muons range from 50 GeV to 86 GeV. The data sample corresponds to an integrated luminosity of 103.5 pb −1 and yields 293 muon-pair events with a hard photon along the beam direction. The events are used to determine the cross sections and the forward-backward charge asymmetries at centre-of-mass energies below the Z resonance.

Abstract: We present a study of the structure of hadronic events recorded by the L3 detector at center-of-mass energies of 130 and 136 GeV. The data sample corresponds to an integrated luminosity of 5 pb-1 collected during the high energy run of 1995. The shapes of the event shape distributions and the energy dependence of their mean values are well reproduced by QCD models. From a comparison of the data with resummed O(alpha_s^2) QCD calculations, we determine the strong coupling constant to be alpha_s(133 GeV) = 0.107 +/- 0.005(exp) +/- 0.006(theor).

Abstract: We report on a search for the excited leptons e ∗ , μ ∗ , τ ∗ and ν ∗ in e + e − collisions at s = 130-140 GeV using the L3 detector at LEP. No evidence has been found for their existence. From an analysis of the expected pair produced l ∗ l ∗ in the channels eeγγ, μμγγ, ττγγ, eeWW, and ννγγ, we determine the lower mass limits at 95% C.L. of 64.7 GeV for e ∗ , 64.9 GeV for μ ∗ , 64.2 GeV for τ ∗ , 57.3 GeV (eW decay mode) and 61.4 GeV (νγ decay mode) for ν ∗ . From an analysis of the expected singly produced ll ∗ in the channels eeγ, μμγ, ττγ, νeW and ννγ, we determine upper limits on the couplings λ m l ∗ up to m l ∗ = 130 GeV .

Abstract: The reaction \epem\ra\epem\gamma^*\gamma^*\ra\epem\kos\kos is studied with the L3 detector at LEP and the formation of the f_2\, \!\!\!'(1525) resonance is observed. For an integrated luminosity of 114 \pb, % \ collected over the years 1991-1994, 31\pm6 f_2\, \!\!\!' events are found. Their angular distribution is consistent with a pure helicity two. The radiative width times the branching ratio is measured to be \Gamma_{\gamma\gamma}(f_2\,\!\!\!')\times Br(f_2\ \!\!\!'\ra \k\bar{\k})=(0.093\pm 0.018\pm 0.022) keV. Only three events are found in the f_2(1270)-a_2(1320) mass region, consistent with destructive f_2-a_2 interference in the \kos\kos \ final state. The mixing angle of the tensor meson nonet is determined to be \theta=(29.4^{+1.4}_{-1.6})^\circ.

Abstract: A search for the decays B d,s 0 → γγ in 2.95 million hadronic Z decays has been performed using the L3 detector at LEP. No candidates are found in the signal region and upper limits have been set on the branching ratios: Br(B d 0 → γ ) −5 and Br(B s 0 → γγ ) −5 at 90% CL. These are the first limits set on these exclusive rare decays.

Abstract: We have searched for anomalous Z → γγγ events with the L3 detector at LEP. No significant deviations from the expected QED e+e− → γγγ events are observed. The branching ratio upper limit for a compoite Z decaying directly into three photons is found to be 1.0 × 10−5 at 95% C.L. The branching ratio upper limits for the process Z → γX, X → γγ are in the range of 0.4 to 1.3 × 10−5, depending on the mass and width of the scalar particle X. In the context of a model with magnetic monopoles coupling to the Z, we find BR(Z → γγγ) < 0.8 × 10−5 at 95% C.L.; this results in a lower mass limit of 510 GeV for a magnetic monopole., Facultad de Ciencias Exactas

Abstract: We have measured the time integrated B0 B 0 mixing parameter and the forward-backward asymmetry in the process e+e− → b b using hadronic events containing muons or electrons. The data sample corresponds to 1,044,000 hadronic decays of the Z. From a fit to the momentum and transverse momentum distributions for single lepton and dilepton events, we have determined the B0 B 0 mixing parameter to be χB = 0.123 ± 0.012 (stat.) ± 0.008 (sys.), and the b b forward-backward asymmetry at the effective center-of-mass energy √s = 91.30 GeV to be A b b = 0.087 ± 0.011 ( stat. ) ± 0.004 ( sys. ) This measurement corresponds to a value of the effective electroweak mixing angle of sin 2 θ w = 0.2335 ± 0.0021 .

Abstract: We search for neutral heavy leptons that are isosinglets under the standard SU(2)L gauge group. Such neutral heavy leptons are expected in many extensions of the standard model. Three types of heavy leptons Ne, N(mu), N(tau) associated with the three neutrino types nu(e), nu(mu), nu(tau) have been directly searched for and no evidence for a signal has been found. We set the limit Br(Z0 --> nu(l)N(l)) < 3 x 10(-5) at the 95% CL for the mass range from 3 GeV up to m(Z).

Abstract: We have measured the forward-backward asymmetry in e + e − → b b and e + e − → c c processes using hadronic events containing muons or electrons. The data sample corresponds to 4100000 hadronic decays of the Z0. From a fit to the single lepton and dilepton p and pT spectra, we determine A b b =0.086±0.015±0.007 and A c c =0.083±0.038±0.027 at the effective center-of-mass energy √s=91.24 GeV. These measurements yield a value of the electroweak mixing angle sin 2 θ w =0.2336±0.0029 .

Abstract: We have measured the total and differential cross sections of the reaction e+e− → γγ(γ) at center-of-mass energies around 91 GeV, with an integrated luminosity of 14.2 pb−1. The results are in good agreement with QED predictions. We set lower limits, at 95% confidence level, on the QED cutoff parameters of Λ+ > 139 GeV, Λ− > 108 GeV and on the mass of an excited electron of m e∗ > 127 GeV . We searched for Z0 rare decays with photonic signitures in the final state. Upper limits, at 95% confidence level, for branching ratio of Z0 decaying into π0γ/γγ, νγ and γγγ are 1.2 × 10−4, 1.8 × 10−4, 3.3 × 10−5 respectively.
