Abstract: We report the results of a search for a W' boson produced in pp collisions at a center-of-mass energy of 1.8 TeV using a 107 pb-1 data sample recorded by the Collider Detector at Fermilab. We consider the decay channel W'-->&munumu and search for anomalous production of high transverse mass munumu lepton pairs. We observe no excess of events above background and set limits on the rate of W' boson production and decay relative to standard model W boson production and decay using a fit of the transverse mass distribution observed. If we assume standard model strength couplings of the W' boson to quark and lepton pairs, we exclude a W' boson with invariant mass less than 660 GeV/c2 at 95% confidence level.

Abstract: We have searched for direct pair production of scalar top and scalar bottom quarks in 88 pb-1 of pp collisions at sqrt[s]=1.8 TeV with the CDF detector. We looked for events with a pair of heavy flavor jets and missing energy, consistent with scalar top (bottom) quark decays to a charm (bottom) quark and a neutralino. The numbers of events that pass our selections show no significant deviation from standard model expectations. We compare our results to the next-to-leading order scalar quark production cross sections to exclude regions in scalar quark-neutralino mass parameter space.

Abstract: We have reconstructed the radiative decays chi(b)(1P)-->Upsilon(1S)gamma and chi(b)(2P)-->Upsilon(1S)gamma in pp collisions at sqrt[s] = 1.8 TeV, and measured the fraction of Upsilon(1S) mesons that originate from these decays. For Upsilon(1S) mesons with p(Upsilon)(T)>8.0 GeV/c, the fractions that come from chi(b)(1P) and chi(b)(2P) decays are [27.1+/-6.9(stat)+/-4. 4(syst)]% and [10.5+/-4.4(stat)+/-1.4(syst)]%, respectively. We have derived the fraction of directly produced Upsilon(1S) mesons to be [50.9+/-8.2(stat)+/-9.0(syst)]%.

Abstract: We have studied the production of B hadrons in 1.8-TeV pp(bar sign) collisions. We present measurements of the fragmentation fractions, f{sub u} , f{sub d} , f{sub s} , and f{sub baryon} , of produced b quarks that yield B{sup +} , B{sup 0} , B{sup 0}{sub s} , and {lambda}{sup 0}{sub b} hadrons. Reconstruction of five electron-charm final states yields f{sub s}/( f{sub u}+f{sub d})=0.213{+-}0.068 and f{sub baryon}/( f{sub u}+f{sub d})=0.118{+-}0.042 , assuming f{sub u}=f{sub d} . If all B hadrons produced in pp(bar sign) collisions cascade to one of these four hadrons, we determine f{sub u}=f{sub d}=0.375{+-}0.023 , f{sub s}=0.160{+-}0.044 , and f{sub baryon}=0.090{+-}0.029 . If we do not assume f{sub u}=f{sub d} , we find f{sub d}/f{sub u}=0.84{+-}0.16 . (c) 2000 The American Physical Society.

Abstract: We search for color singlet technirho and technipion production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\phantom{\rule{0ex}{0ex}}\mathrm{TeV}$ recorded with the Collider Detector at Fermilab. These exotic technimesons are present in a model of walking technicolor. The signatures studied are lepton plus two jets plus ${E}_{T}$ and multijet final states. No excess of events is seen in either final state. We set an upper limit on the technirho production cross section and exclude a region in the technipion mass versus technirho mass plane.

Abstract: We present the results of a search for pair production of a fourth-generation charge -1 / 3 quark (b(')) in sqrt[s] = 1.8 TeV pp collisions using 88 pb(-1) of data obtained with the Collider Detector at Fermilab. We assume that both quarks decay via the flavor-changing neutral current process b(')-->bZ(0) and that the b(') mass is greater than m(Z)+m(b). We studied the decay mode b(')b(');-->Z(0)Z(0)bb where one Z0 decays into e(+)e(-) or m(+)m(-) and the other decays hadronically, giving a signature of two leptons plus jets. An upper limit on the sigma(pp-->b(')b(');)x[B(b(')-->bZ(0))](2) is established as a function of the b(') mass. We exclude at 95% confidence level a b(') quark with mass between 100 and 199 GeV/c(2) for B(b(')-->bZ(0)) = 100%.

Abstract: We measure the relative rate of production of orbitally excited (L = 1) states of B mesons (B**) by observing their decays into B pi (+/-). We reconstruct B mesons through semileptonic decay channels using data collected in p(p) over bar collisions at roots = 1.8 TeV. The fraction of light B mesons that are produced as L = 1B** states is measured to be 0.28 +/- 0.06(stat) +/- 0.03(syst). We also measure the collective mass of the B** states, and quantify the result by quoting the (model-dependent) mass of the lowest B** state to be m(B-1) = 5.71 +/- 0.02 GeV/c(2).

Abstract: We have searched for direct pair production of scalar top and scalar bottom quarks in 88 pb-1 of pp collisions at sqrt[s]=1.8 TeV with the CDF detector. We looked for events with a pair of heavy flavor jets and missing energy, consistent with scalar top (bottom) quark decays to a charm (bottom) quark and a neutralino. The numbers of events that pass our selections show no significant deviation from standard model expectations. We compare our results to the next-to-leading order scalar quark production cross sections to exclude regions in scalar quark-neutralino mass parameter space.

Abstract: We report the results of a search for a W' boson produced in pp collisions at a center-of-mass energy of 1.8 TeV using a 107 pb-1 data sample recorded by the Collider Detector at Fermilab. We consider the decay channel W'-->andmunumu and search for anomalous production of high transverse mass munumu lepton pairs. We observe no excess of events above background and set limits on the rate of W' boson production and decay relative to standard model W boson production and decay using a fit of the transverse mass distribution observed. If we assume standard model strength couplings of the W' boson to quark and lepton pairs, we exclude a W' boson with invariant mass less than 660 GeV/c2 at 95% confidence level.

Abstract: This paper reports an updated measurement of the standard model CP violation parameter sin 2{beta} using the CDF Detector at Fermilab. The entire run I data sample of 110 pb{sup -1} of proton-antiproton collisions at {radical}(s)=1.8 TeV is used to identify a signal sample of {approx}400 B{yields}J/{psi} K{sub S}{sup 0} events, where J/{psi}{yields}{mu}{sup +}{mu}{sup -} and K{sub S}{sup 0}{yields}{pi}{sup +}{pi}{sup -}. The flavor of the neutral B meson is identified at the time of production by combining information from three tagging algorithms: a same-side tag, a jet-charge tag, and a soft-lepton tag. A maximum likelihood fitting method is used to determine sin 2{beta}=0.79{sub -0.44}{sup +0.41}(stat+syst). This value of sin 2{beta} is consistent with the standard model prediction, based upon existing measurements, of a large positive CP-violating asymmetry in this decay mode.

Abstract: The oscillation frequency {delta}m{sub d} of B{sup 0}B(bar sign){sup 0} mixing is measured using the partially reconstructed semileptonic decay B(bar sign){sup 0}{yields}l{sup -}{nu}(bar sign)D{sup *+}X. The data sample was collected with the CDF detector at the Fermilab Tevatron collider during 1992-1995 by triggering on the existence of two lepton candidates in an event, and corresponds to about 110 pb{sup -1} of p(bar sign)p collisions at {radical}(s)=1.8 TeV. We estimate the proper decay time of the B(bar sign){sup 0} meson from the measured decay length and reconstructed momentum of the l{sup -}D{sup *+} system. The charge of the lepton in the final state identifies the flavor of the B(bar sign){sup 0} meson at its decay. The second lepton in the event is used to infer the flavor of the B(bar sign){sup 0} meson at production. We measure the oscillation frequency to be {delta}m{sub d}=0.516{+-}0.099{sub -0.035}{sup +} {sup 0.029} ps{sup -1}, where the first uncertainty is statistical and the second is systematic.

Using a ${70\ensuremath{-}\mathrm{p}\mathrm{b}}^{\mathrm{\ensuremath{-}}1}$ sample of low-mass dimuon trigger data recorded with the Collider Detector at Fermilab, we identify B mesons by observing the double semileptonic decays $\stackrel{\ensuremath{\rightarrow}}{b}c\ensuremath{\mu}X$ with $\stackrel{\ensuremath{\rightarrow}}{c}s\ensuremath{\mu}X.$ By counting the numbers of ${K}^{*}{(892)}^{0},$ ${K}^{*}{(892)}^{+},$ and \ensuremath{\varphi}(1020) mesons produced in association with these muon pairs, we measure the ratio of strange to nonstrange B meson production to be ${f}_{s}{/(f}_{u}{+f}_{d})=[21.0\ifmmode\pm\else\textpm\fi{}3.6(\mathrm{stat}{)}_{\ensuremath{-}3.0}^{+3.8}(\mathrm{syst})]%.$ This measurement is the most precise available from hadron collisions to date. Limits on the branching fractions of semileptonic charm meson decays with ${K}_{1}(1270),$ ${K}_{1}^{*}(1410),$ and ${K}_{2}^{*}(1430)$ mesons in the final state are also obtained.

Abstract: We present a measurement of the mass difference {Delta}m{sub d} for the B{sup 0} meson and the statistical power of the b flavor tagging methods used. The measurement uses 90 pb{sup -1} of data from p{ovr p} collisions at sqrt[s]=1.8 TeV collected with the CDF detector. An inclusive lepton trigger is used to collect a large sample of B hadron semileptonic decays. The mass difference {Delta}m{sub d} is determined from the proper time dependence of the fraction of B hadrons that undergo flavor oscillations. The flavor at decay is inferred from the charge of the lepton from semileptonic B decay. The initial flavor is inferred by determining the flavor of the other B hadron produced in the collision, either from its semileptonic decay (soft-lepton tag) or from its jet charge. The measurement yields {Delta}m{sub d}=(0.500{+-}0.052{+-}0.043){Dirac_h} ps{sup -1}, where the first uncertainty is statistical and the second uncertainty is systematic. The statistical powers ({var_epsilon}D{sup 2}) of the soft-lepton and jet-charge flavor taggers are (0.91{+-}0.10{+-}0.11)% and (0.78{+-}0.12{+-}0.08)%, respectively.

Abstract: ${B}_{d}^{0}\ensuremath{-}{B}_{d}^{0}$ oscillations are observed in ``self-tagged'' samples of partially reconstructed $B$ mesons decaying into a lepton and a charmed meson collected in $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{TeV}.$ A flavor tagging technique is employed which relies upon the correlation between the flavor of $B$ mesons and the charge of a nearby particle. We measure the flavor oscillation frequency to be $\ensuremath{\Delta}{m}_{d}{=0.471}_{\ensuremath{-}0.068}^{+0.078}\ifmmode\pm\else\textpm\fi{}0.034{\mathrm{ps}}^{\mathrm{\ensuremath{-}}1}.$ The tagging method is also demonstrated in exclusive samples of ${B}_{u}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{+}$ and ${B}_{d}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{*0}(892),$ where similar flavor-charge correlations are observed. The tagging characteristics of the various samples are compared with each other, and with Monte Carlo simulations.

Abstract: We have searched for direct pair production of scalar top and scalar bottom quarks in 88 pb-1 of pp collisions at sqrt[s]=1.8 TeV with the CDF detector. We looked for events with a pair of heavy flavor jets and missing energy, consistent with scalar top (bottom) quark decays to a charm (bottom) quark and a neutralino. The numbers of events that pass our selections show no significant deviation from standard model expectations. We compare our results to the next-to-leading order scalar quark production cross sections to exclude regions in scalar quark-neutralino mass parameter space.

Abstract: We report the results of a search for a W' boson produced in pp collisions at a center-of-mass energy of 1.8 TeV using a 107 pb-1 data sample recorded by the Collider Detector at Fermilab. We consider the decay channel W'-->&munumu and search for anomalous production of high transverse mass munumu lepton pairs. We observe no excess of events above background and set limits on the rate of W' boson production and decay relative to standard model W boson production and decay using a fit of the transverse mass distribution observed. If we assume standard model strength couplings of the W' boson to quark and lepton pairs, we exclude a W' boson with invariant mass less than 660 GeV/c2 at 95% confidence level.

20. Production of Upsilon(1S) mesons from chi(b) decays in p&pmacr; collisions at sqrt

Author: Toyoda H, Trischuk W, de Troconiz JF, Truitt S, Tseng J, Turini N, Ukegawa F, Valls J, Vejcik S 3rd, Velev G, Vidal R, Vilar R, Vologouev I I, Vucinic D, Wagner RG, Wagner RL, Wahl J, Wallace NB, Walsh AM, Wang C, Wang CH, Wang MJ, Watanabe T, Waters D, Watts T, and Webb R
Abstract: We have reconstructed the radiative decays chi(b)(1P)-->Upsilon(1S)gamma and chi(b)(2P)-->Upsilon(1S)gamma in p&pmacr; collisions at sqrt[s] = 1.8 TeV, and measured the fraction of Upsilon(1S) mesons that originate from these decays. For Upsilon(1S) mesons with p(Upsilon)(T)>8.0 GeV/c, the fractions that come from chi(b)(1P) and chi(b)(2P) decays are [27.1+/-6.9(stat)+/-4. 4(syst)]% and [10.5+/-4.4(stat)+/-1.4(syst)]%, respectively. We have derived the fraction of directly produced Upsilon(1S) mesons to be [50.9+/-8.2(stat)+/-9.0(syst)]%.

Abstract: We have studied the production of B hadrons in 1.8-TeV pp[over ¯] collisions. We present measurements of the fragmentation fractions, f_{u}, f_{d}, f_{s}, and f_{baryon}, of produced b quarks that yield B^{+}, B^{0}, B_{s}^{0}, and Λ[over ¯]_{b}^{0} hadrons. Reconstruction of five electron-charm final states yields f_{s}/( f_{u}+f_{d})=0.213±0.068 and f_{baryon}/( f_{u}+f_{d})=0.118±0.042, assuming f_{u}=f_{d}. If all B hadrons produced in pp[over ¯] collisions cascade to one of these four hadrons, we determine f_{u}=f_{d}=0.375±0.023, f_{s}=0.160±0.044, and f_{baryon}=0.090±0.029. If we do not assume f_{u}=f_{d}, we find f_{d}/f_{u}=0.84±0.16.

22. Search for color singlet technicolor particles in p&pmacr; collisions at radicals = 1.8 TeV

Abstract: We search for color singlet technirho and technipion production in p&pmacr; collisions at sqrt[s] = 1.8 TeV recorded with the Collider Detector at Fermilab. These exotic technimesons are present in a model of walking technicolor. The signatures studied are lepton plus two jets plus E(T) and multijet final states. No excess of events is seen in either final state. We set an upper limit on the technirho production cross section and exclude a region in the technipion mass versus technirho mass plane.

Abstract: We present the results of a search for pair production of a fourth-generation charge -1 / 3 quark (b(')) in sqrt[s] = 1.8 TeV p&pmacr; collisions using 88 pb(-1) of data obtained with the Collider Detector at Fermilab. We assume that both quarks decay via the flavor-changing neutral current process b(')-->bZ(0) and that the b(') mass is greater than m(Z)+m(b). We studied the decay mode b(')b(');-->Z(0)Z(0)b&bmacr; where one Z0 decays into e(+)e(-) or &mgr;(+)&mgr;(-) and the other decays hadronically, giving a signature of two leptons plus jets. An upper limit on the sigma(p&pmacr;-->b(')b(');)x[B(b(')-->bZ(0))](2) is established as a function of the b(') mass. We exclude at 95% confidence level a b(') quark with mass between 100 and 199 GeV/c(2) for B(b(')-->bZ(0)) = 100%.

26. Measurement of the helicity of W bosons in top quark decays

Author: Ukegawa F, Valls J, Vejcik S 3rd, Velev G, Vidal R, Vilar R, Vologouev I I, Vucinic D, Wagner RG, Wagner RL, Wahl J, Wallace NB, Walsh AM, Wang C, Wang CH, Wang MJ, Watanabe T, Watts T, Webb R, Wenzel H, Wester WC 3rd, Wicklund AB, Wicklund E, Williams HH, Wilson P, and Winer BL
Abstract: We use the transverse momentum spectrum of leptons in the decay chain t-->bW with W-->lnu to measure the helicity of the W bosons in the top quark rest frame. Our measurement uses a t&tmacr; sample isolated in 106+/-4 pb(-1) of data collected in p&pmacr; collisions at sqrt[s] = 1.8 TeV with the CDF detector at the Fermilab Tevatron. Assuming a standard V-A weak decay, we find that the fraction of W's with zero helicity in the top rest frame is F0 = 0.91+/-0. 37(stat)+/-0.13(syst), consistent with the standard model prediction of F0 = 0.70 for a top mass of 175 GeV/c(2).
