A Search for New Particles in 2 Decay*
نویسنده
چکیده
We have searched 310 hadronic 2 decays for evidence of new quarks and leptons. We set lower mass limits of 40.7 GeV/c2 for top, 45 GeV/c2 for bottom prime, and 42.4 GeV/c2 for a heavy neutral lepton assuming their decays are predominantly via the charged current. Limits are also set for other decay modes and for mixtures of decay modes. Extended version of paper presented at the International Europhysics Conference on High Energy Physics, Madrid, Spain, September 6-13, 1989. * Work supported by Department of Energy contract DE-AC03-76SF00515. o Reporting on behalf of the Mark II Collaboration.

متن کاملNonsense-mediated mRNA decay among coagulation factor genes
Objective(s): Haemostasis prevents blood loss following vascular injury. It depends on the unique concert of events involving platelets and specific blood proteins, known as coagulation factors. The clotting system requires precise regulation and coordinated reactions to maintain the integrity of the vasculature. Clotting insufficiency mostly occurs due to genetically inherited coagulation fact...
متن کاملModeling the distribution of deposited energy by alpha particles from Radon 223 decay and its effect on DNA
The ionizing radiations, through physical and chemical processes, lead to simple and complex single- and double- strand breaks, as well as base lesions to the DNA. In this study, taking into account all the physical and chemical processes involved in the interaction of ionizing radiation with matter, the initial damage induced to DNA was evaluated for 5.7 MeV alpha-rays from Radon 223 isotope....
متن کاملTheoretical determination of ηb’s electromagnetic decay width
First evidence of ηb was given in 2001 by ALEPH [1]. The search for ηb is done in the decay channel into two photons. One candidate event is found in the six–charged particle final state and none in the four–charged particle final state, giving the upper limits: Γ(ηb → γγ) × BR(ηb → 4 charged particles) < 48 eV , Γ(ηb → γγ) × BR(ηb → 6 charged particles) < 132 eV . This observation was the main...

These areas have gradually become a place for social harms and are vulnerable to natural disasters, the existing ...
