Not Strange but Bizarre Physics from the Sample Experiment
نویسنده
چکیده
Since the report of the SAMPLE Collaboration suggesting the strange-quark contribution to the nucleon, G M (0), may be greater than zero, numerous models have appeared supporting positive values for G M (0). In this paper the bizarre physics associated with G M (0) > 0 is illustrated. Using new lattice QCD results, our best estimate for G M (0) shifts slightly from G M (0) = −0.75 ± 0.30 μN , to G M (0) = −0.62± 0.26 μN .

Bizarreness and Emotion Identification in Grete Stern Photomontages: Gender and Age Disparities
Although the International Affective Picture System (IAPS) is used to evaluate emotions (valence, arousal, and dominance evoked by a large set of photographs), bizarre images in works of art have not been assessed with the IAPS procedures. Understood here as strange, non-sense, and absurd mental contents or expressions accompanied by surprise and confusion emotions, bizarreness was assessed aft...
متن کاملRings of Singularities
This paper is a slightly revised version of an introduction into singularity theory corresponding to a series of lectures given at the ``Advanced School and Conference on homological and geometrical methods in representation theory'' at the International Centre for Theoretical Physics (ICTP), Miramare - Trieste, Italy, 11-29 January 2010. We show how to associate to a triple of posit...
متن کاملFrom the strange to the bizarre : Another reply to Cappelen and Lepore
If you think that semantic minimalism is the only alternative to contextualism but you’d rather do without Cappelen and Lepore’s mysteriously minimal “propositions,” you can. You just have to recognize that being semantically incomplete does not make a sentence context-sensitive. You don’t have to go through the ritual of repeatedly incanting things like this: “John is ready” expresses the prop...
متن کاملDetermining and Optimizing Effective Factors in Laser Irradiation on Skin Tensional Strength using a Hybrid DOE and DEA Approach
Introduction: We investigated the characteristic of a suitable irradiation on skin's tensional strength using design of experiments (DOE). The experiments in this research are designed in two phases and data envelopment analysis (DEA) is used for performance measurement of each phase. Material and Methods: Samples were provided from pleura as surface tissue made of collagen and elastin fibers. ...
متن کاملSample: Parity Violating Electron Scattering from Hydrogen and Deuterium
Recently, there has been considerable theoretical interest in determining strange quark contributions to hadronic matrix elements. Such matrix elements can be accessed through the nucleon’s neutral weak form factors as determined in parity violating electron scattering. The SAMPLE experiment will measure the strange magnetic form factor GM at low momentum transfer. By combining measurements fro...
