Journal ArticleDOI

Measurements of R and a search for heavy-quark production in e+e- annihilation at sqrt s =50 and 52 GeV.

Hiroyuki Sagawa, +112 more
TL;DR: A 95%-confidence-level upper limit is deduced for the production rate of new heavy charge +(2/3e or -(1/ 3e quarks to be 0.19 units of R) for hadronic final states.
Journal ArticleDOI

Search for isolated leptons in low-thrust e+e- annihilation events at square-root-s=50 and 52 gev

S. Igarashi, +109 more
TL;DR: The number of low-thrust events with isolated leptons is consistent with the expectation of the standard model with five quark flavors as discussed by the authors, and limits on the production of new quarks and leptonons are reported.
Journal ArticleDOI

Search for the substructure of leptons in high energy QED processes at tristan

S. K. Kim, +106 more
- 15 Jun 1989 - 
TL;DR: In this paper, a possible substructure of the electron and muon is investigated in terms of chiral invariant contact interactions and also in the absence of excited lepton production.
Journal ArticleDOI

Measurements of cross sections and charge asymmetries for e+e−→τ+τ−and e+e−→μ+μ−for s from 52 to 57 GeV

A. Bacala, +107 more
- 09 Feb 1989 - 
TL;DR: In this paper, the forward-backward asymmetries and total cross sections for these reactions are found to be in agreement with predictions of the standard model of the electro-weak interactions.
Journal ArticleDOI

Experimental mass limit for a fourth-generation sequential lepton from e+e- annihilations at s=56 GeV

G. N. Kim, +104 more
TL;DR: In this article, a search for pair production for fourth-generation sequential leptons in e/sup +/e/sup -/ annihilation at a center-of-mass energy = 56 GeV is reported.
