Decisive test of superstring-inspired E(6) models.
We point out that in a large class of superstring–inspired E(6) models, either an e+e− collider operating at a center–of–mass energy √ s = 1.5 TeV or higher must detect the pair production of charged or neutral exotic leptons, or an e+e− collider with √ s ≥ 300 GeV must discover at least one light neutral Higgs boson with invisible branching ratio exceeding 50%. If neither of these two signals ...

متن کاملAnalysing Decisive Stochastic Processes
In 2007, Abdulla et al. introduced the elegant concept of decisive Markov chain. Intuitively, decisiveness allows one to lift the good properties of finite Markov chains to infinite Markov chains. For instance, the approximate quantitative reachability problem can be solved for decisive Markov chains (enjoying reasonable effectiveness assumptions) including probabilistic lossy channel systems a...
متن کاملDecisive Markov Chains
We consider qualitative and quantitative verification problems for infinitestate Markov chains. We call a Markov chain decisive w.r.t. a given set of target states F if it almost certainly eventually reaches either F or a state from which F can no longer be reached. While all finite Markov chains are trivially decisive (for every set F ), this also holds for many classes of infinite Markov chai...
متن کاملA Theory of Decisive Leadership
We present a theory that rationalizes voters’ preference for decisive leaders. Common definitions of decisiveness reference the speed of decision making. Although greater speed can be good or bad, agency problems between voters and politicians create a natural preference among voters for leaders who have a greater aversion to delay or more self-knowledge than the voters, and hence who make deci...
