ON THE SPECIAL SIGNIFICANCE OF THE LATEST PAMELA RESULTS IN ASTROPARTICLE PHYSICS

Abstract

In continuation of their earlier measurements, the PAMELA group reported data on antiproton flux and [Formula: see text] ratios in 2010 at much higher energies. In the past we had dealt with these specific aspects of PAMELA data in great detail and each time we captured the contemporary data-trends quite successfully with the help of a multiple production model of secondary antiprotons with some nonstandard ilk and with some other absolutely standard assumptions and approximations. In this work we aim at presenting a comprehensive and valid description of all the available data on antiproton flux and the nature of [Formula: see text] ratios at the highest energies reported so far by the PAMELA experiment in 2010. The main physical implication of all this would, in the end, be highlighted.
