On the Special Significance of the Latest PAMELA Results in Astroparticle Physics
In continuation of their earlier measurements, the PAMELA group reported data
on antiproton flux and ratios in 2010 at much higher energies. In
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
non-standard 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
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.Comment: 8 pages, 6 figure
Production of J/-Particles at RHIC and LHC energies: An Alternative `Psi'-chology
We attempt here to understand successfully some crucial aspects of
-production in some high energy nuclear collisions in the light of a
non-standard framework outlined in the text. It is found that the results
arrived at with this main working approach here is fairly in good agreement
with both the measured data and the results obtained on the basis of some other
models of the `standard' variety. Impact and implications of this comparative
study have also been precisely highlighted in the end.Comment: 14 pages, 7 figures, to appear in Open Journal of Microphysics. arXiv

On Production of Hadrons in Proton-Proton Collisions at RHIC and LHC Energies and an Approach
From the very early days of Particle Physics, both experimental and
theoretical studies on proton-proton collisions had occupied the center-stage
of attention for very simple and obvious reasons. And this intense interest
seems now to be at peak value with the onset of the Large Hadron Collider
(LHC)-studies at TeV ranges of energies. In this work, we have chosen to
analyse the inclusive cross-sections, the rapidity density, the and
-ratio behaviours and the -values, in the light of the Sequential
Chain Model (SCM). And the limited successes of the model encourage us to take
up further studies on several other aspects of topmost importance in particle
physics with the same approach.Comment: 14 pages, 3 tables, 7 figures; to appear in Journal of Modern Physic
