Pate Física, Astronomía y Matemáticas strangeness protons and neutrons Electromagnetic form factors The recent parity-violating ep forward-scattering elastic asymmetry data from Jefferson Lab (HAPPEx and G0), when combined with the νp elastic cross section data from Brookhaven (E734), permit an extraction of the strangeness contribution to the vector and axial nucleon form factors for momentum transfers in the range 0.45 < Q2 < 1.0 GeV2 . These results, combined with the recent determination of the strange vector form factors at Q2 = 0.1 GeV2 (SAMPLE, HAPPEx, PVA4, G0) have been interpreted in terms of uuds ̄ configurations s very different from the kaon-loop configurations usually associated with strangeness in the nucleon. New experiments are being proposed to improve the state of our knowledge of the νp elastic cross section — these new experiments will push the range of Q2 to much lower values, and greatly increase the precision of the νp elastic data. One outcome of this can be a measurement of the strangeness contribution to the nucleon spin, ∆s. Nuclear targets (e.g. C or Ar) are to be used in these neutrino experiments, and so a deep understanding of the nuclear physics, particularly in regard to final state effects, is needed before the potential of these precision experiments can be fully realized. 2007 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57028300014 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
