This re veals a missed property of spin. In addition to the usual up and down pola rized states that are measured\, two additional coherent states for L and R helicity are found. This is not the usual helicity defined in particle physics\, but an additional attribute of spin. Under the quaternion group\ , symmetric polarizations are described by the Pauli spin vector\, $\\sigm a$ and the antisymmetric helicity by the bivector\, $i\\sigma$. Moreover\ , surprisingly\, the four states of quaternion spin form one particle in t he Dirac field which replaces the interpretation of Dirac whereby the two- dimensional Dirac spin and its mirror are treated as measured spin and its antimatter twin.\n\nPolarization and coherence are two complementary elem ents of reality\, analogous to position-momentum\; angular momentum and an gle\; and energy and time.\n\nMoreover\, it is found that the helicity acc ounts for the correlation found in coincident EPR experiments which give a n apparent violation of Bell’s Inequalities. As seen in the figure\, th e simulation gives the correlation and more that is observed in experiment . The simulation is trivial\, simply finding which way the spin axis spin s. \n\nThe talk is pedagogical with simple geometric arguments to describe a separated EPR pair with no entanglement. This obviates the need for no n-local connectivity between Alice and Bob and shows that the apparent vio lation of Bell’s Inequalities is evidence for local realism\, and not no n-locality.\n\nThe theory has no Local Hidden Variables\, so Bell’s Theo rem is irrelevant\, and always satisfied.\n LOCATION:https://researchseminars.org/talk/QMFNoT/42/ END:VEVENT END:VCALENDAR
