TL;DR: In this article, the Weinberg-Salam model was used to place constraints on fermion and Higgs Boson masses and it was shown that spontaneous symmetry breakdown cannot generate fermions in excess of about 300 GeV.

TL;DR: In this article, the authors used the standard model of the early universe to estimate the present abundances of possible absolutely-stable hadrons or charged leptons more massive than the proton.
138 citations
TL;DR: In this paper, a complete set of rotationally invariant observables (Hl) is presented to characterize the shape of the final states in e+e− annihilation processes.
111 citations
TL;DR: In this paper, a new class of observables which distinguish events containing two or three hadron jets from those containing a larger number of jets is presented. But their use should allow the mechanism of decay to be determined.

TL;DR: In this paper, the electromagnetic-radiative-correction factors to deep-inelastic neutrino-nucleon scattering are estimated using the parton-model formulas of Kiskis.
Abstract: The electromagnetic-radiative-correction factors to deep-inelastic neutrino-nucleon scattering are estimated using the parton-model formulas of Kiskis. Tables and approximate formulas are given for the benefit of experimenters wishing to estimate their own corrections. The corrections tend to be less than about 10%, and vary only slowly with energy, ${Q}^{2}$, and $x$.

TL;DR: In this article, the authors calculate the production of heavy-charged or strongly interacting particles by cosmic rays and find that any sufficiently light stable hadrons should be detectable in static terrestrial searches.
Abstract: We calculate the production of heavy-charged or strongly interacting particles by cosmic rays and find that any sufficiently light stable ones should be detectable in static terrestrial searches. Stable or nearly stable heavy hadrons would also be visible with a distinct signature in delayed-particle cosmic-ray experiments.

TL;DR: In this paper, various aspects of theoretical high-energy physics are discussed, including methods for investigating QCD effects in annihilation to hadrons, and some predictions for various features of QCD jets.
Abstract: This thesis discusses various aspects of theoretical high-energy physics. The first two sections describe methods for investigating QCD effects in e⁺e⁻ annihilation to hadrons. The third section presents some predictions for various features of QCD jets. The fourth section shows that any fermions in the standard weak interaction model must have masses ≾100 GeV. In the fifth section, the abundances of any new absolutely stable heavy particles which should have been produced in the early universe are estimated, and found to be inconsistent with observational limits. Finally, the sixth section describes the development of a baryon excess in the very early universe due to B, CP violating interactions.

TL;DR: In this paper, it was pointed out that weak interactions should admix a small parity-violating E1 component into the M1 electromagnetic decay, and weak interactions admixed the parityviolating component to the M 1 electromagnetic decay.
