Paradigm Shifts and a Possible Resolution of the PAMELA-Paradox in Astroparticle Physics

TL;DR

This paper proposes new ideas about particle structure and production mechanisms to explain the PAMELA paradox, where positron flux rises sharply at high energies while antiproton flux does not.

Contribution

It introduces novel concepts in particle structure and multiparticle production to resolve the PAMELA paradox in astroparticle physics.

Findings

Successful explanation of positron flux rise

Consistent interpretation of antiproton flux behavior

New theoretical framework for high-energy cosmic ray particles

Abstract

Very recently, PAMELA Collaboration has formally reported two sets of data on positron and antiproton flux measurements done at very high energies and with unprecedented accuracy. The reports reveal a puzzle of great topical interest and importance : it is decisively found that there is a sharp smooth rise of the positron fraction, whereas for antiproton production no such rises occur; rather the fraction either flattens, or shows signs of falling off gradually with increasing energies. The present work is just an attempt to decipher the riddle with the help of a host of radically new ideas about the particle-structure, the multiparticle-production mechanisms and the concept of nucleon break-downs into the constituent partons. The application of these ideas found remarkable successes in the past; exactly similar or more striking are the findings by the present study.
