Experimental disagreements with Extended Unitarity
In production processes, e.g. J/Ψ → ωππ or p̄p → 3π, the σ and f0(980) overlap in the same partial wave. The conjecture of Extended Unitarity (EU) states that the ππ pair should have the same phase variation as ππ elastic scattering. This is an extension of Watson’s theorem beyond its original derivation, which stated only that the s-dependence of a single resonance should be universal. The pred...
متن کاملParticle Swarm Optimization with Disagreements
This paper introduces an enhancement to the particle swarm optimization algorithms that models a characteristic of social groups: the disagreements between individuals. After a short introduction, we describe the new concept theoretically and define a special type of particle swarm optimization with disagreements: the 6σ-PSOD. Based on it, we conduct some tests proving that it can perform bette...
متن کاملAnalyzing Disagreements
We address the problem of distinguishing between two sources of disagreement in annotations: genuine subjectivity and slip of attention. The latter is especially likely when the classification task has a default class, as in tasks where annotators need to find instances of the phenomenon of interest, such as in a metaphor detection task discussed here. We apply and extend a data analysis techni...
متن کاملAgreements Without Disagreements
The first part of this paper presents a coalition formation method for multi-agent systems which finds a Pareto optimal solution without aggregating the preferences of the agents. This protocol is adapted to problems requiring coordination by coalition formation, where it is undesirable, or not possible, to aggregate the preferences of the agents. The second part proposes an extension of this m...
متن کاملDisagreements on Collegial Courts : A
How do disagreements between judges on collegial (multimember) courts affect legal policy? We address this question by developing an account of the nature of judicial disagreements in the case-space model of judicial choice. We distinguish between different types of disagreement, from disagreements about case facts to disagreements about how legal rules should treat varying case facts, and cons...
