Abstract

We propose an alternative interpretation of the top events discovered at the Fermilab Tevatron in 1995. Given that the charge of the {ital b} quark jet cannot be measured for the whole sample with certainty, the signal can be due to a quark of charge {minus}4/3 at the reported mass, i.e., 174 GeV, while the top quark is actually heavier, say above 230 GeV. We point out in this paper that such a scenario is actually hinted at by the latest precision electroweak measurements of {ital Z} decay. To rule out this possibility in the future, the {ital b} quark jet charge analysis has to become definitive, or the single {open_quotes}top{close_quotes} production cross section has to be measured. {copyright} {ital 1999} {ital The American Physical Society}

Measurement of the W boson helicity in top-antitop quark events with the CDF II experiment

Technical Report Chwalek, Thorsten

In 1995 the top quark was discovered at the Tevatron proton-antiproton collider at Fermilab by the CDF and D0 collaborations [1, 2]. It is the most massive known elementary particle and its mass is currently measured with a precision of about 1.3% [3, 4]. However, the measurements of several other top quark properties are still statistically limited, so the question remains whether the Standard Model of elementary particle physics successfully predicts these properties. This thesis addresses one interesting aspect of top quark decay, the helicity of the produced W boson. Until the start of the Large Hadron Collider (LHC) atmore »« less

Search for top-quark decays to real /ital W/ bosons at the Fermilab Tevatron collider

Journal Article Baer, H; Barger, V; Phillips, R - Phys. Rev. D; (United States)

We propose ways in which eventual signals from heavy-top-quark decays into on-shell or nearly-on-shell /ital W/ bosons may be discriminated more sharply from background at the Fermilab Tevatron /ital p/bar /p/ collider. For single-lepton /ital t/bar /t/ signals, the principal background from direct /ital W/ production cannot be eliminated by acceptance cuts alone, but the signal/background ratio can be greatly increased by requiring a high jet multiplicity /ital n/. Top-quark signals can be detected and /ital m//sub /ital t// can be measured via enhancements in the single-lepton event rates at high /ital n/, or via a peak in the invariantmore »« less

Singlet charge 2/3 quark hiding the top quark: Fermilab Tevatron and CERN LEP implications

Journal Article Hou, W; Huang, H - Physical Review, D

If {ital c} and {ital t} quarks are strongly mixed with a weak singlet charge 2/3 quark, {ital B}({ital t}{r_arrow}{ital l}{nu}+{ital X}) could be suppressed via the {ital t}{r_arrow}{ital cH}{sup 0} mode; thereby, the top quark could still hide below {ital M}{sub {ital W}}, whereas the heavy quark signal observed at the Fermilab Tevatron is due to the dominantly singlet quark {ital Q}. This may occur without affecting the small {ital m}{sub {ital c}} value. Demanding {ital m}{sub {ital Q}}{congruent}175 GeV and {ital m}{sub {ital t}}{approx_lt}{ital M}{sub {ital W}}, we find that {ital B}({ital t}{r_arrow}{ital l}{nu}+{ital X}) cannot be toomore »« less

Search for top squarks at the Fermilab Tevatron collider

Journal Article Baer, H; Sender, J; Tata, X - Physical Review, D (Particles Fields); (United States)

The lighter superpartner of the top quark ([ital [tilde t]][sub 1]) may be considerably lighter than squarks of the first two generations, and hence may be accessible to Fermilab Tevatron collider searches, even if the other squarks and the gluino are too heavy. For the range of [ital m][sub [ital [tilde t]]1] of interest at the Tevatron, the [ital [tilde t]][sub 1] decays to a chargino via [ital [tilde t]][sub 1][r arrow][ital b[tilde W]][sub 1] if this is kinematically allowed; otherwise, the flavor-changing loop decay [ital [tilde t]][sub 1][r arrow][ital c[tilde Z]][sub 1] dominates. In the latter case, [ital [tildemore »« less

Studies of top quark properties and search for electroweak single top quark production at the Tevatron

Conference Datta, Mousumi

The top quark was discovered in 1995 by the CDF and D0 experiments at the Fermilab Tevatron during the Run I operation. Since the start of the Tevatron Run II in 2001, both experiments have collected {approx}2 fb{sup -1} data samples, which are over twenty times larger than that used in the Run 1 discovery. This larger data sample allows more precise studies of top-quark properties; differences between observed top-quark properties and the Standard Model (SM) prediction may give hints to possible physics beyond the SM. Here we present the latest results on the measurements of top-quark properties and themore »« less
