Sn1987a: Temporal Models

Abstract

It is well known that carriers of astrophysical information are massless spinning particles. These carriers are photons, neutrinos and, expectedly, gravitons. All these particles are emitted during supernova events. Information carried by these particles characterize their sources, but such information are affected by the trajectories of the carriers. Recently, it is shown that these trajectories are spin dependent. Knowing these trajectories and the arrival times of such particles to the detectors, a spin dependent model is constructed and compared with the conventional spin independent model.

A New Class of Path Equations in Ap-Geometry

“…One of the authors of the present work [2] has generalized this set of equations and suggested that the torsion term represents a type of interaction between the torsion of the background gravitational field and the quantum spin of the moving particle. The generalized path equation mentioned above has been used , in its linearized form, to interpret [3] qualitatively and quantitatively the discrepancy in the COW-experiment. Also, the same equation has been used [4] to explain the time delay of massless spinning particles received from SN1987A.…”

Also, the same equation has been used [4] to explain the time delay of massless spinning particles received from SN1987A. It is to be considered that the generalized path equation can be used to describe trajectories of spinning particle in any gravity theory (including General Relativity) if it is written in the AP-geometry.…”
