Analytical Description of Hadron-Hadron Scattering via Principle of Minimum Distance in Space of States
In this paper an analytical description of the hadron-hadron scattering is
presented by using PMD-SQS-optimum principle in which the differential cross
sections in the forward and backward c.m. angles are considered fixed from the
experimental data. Experimental tests of the PMD-SQS-optimal predictions,
obained by using the available phase shifts, as well as from direct
experimental data, are presented. It is shown that the actual experimental data
for the differential cross sections of all principal hadron-hadron
[nucleon-nucleon, antiproton-proton, mezon-nucleon] scatterings at all energies
higher than 2 GeV, can be well systematized by PMD-SQS predictions.Comment: 18 pages, 10 figure
Convergence rate of Tsallis entropic regularized optimal transport
In this paper, we consider Tsallis entropic regularized optimal transport and
discuss the convergence rate as the regularization parameter goes
to . In particular, we establish the convergence rate of the Tsallis
entropic regularized optimal transport using the quantization and shadow
arguments developed by Eckstein--Nutz. We compare this to the convergence rate
of the entropic regularized optimal transport with Kullback--Leibler (KL)
divergence and show that KL is the fastest convergence rate in terms of Tsallis
relative entropy.Comment: 21 page
Neural complexity -- Statistical-mechanical approach of human electroencephalograms
The brain is a complex system whose understanding enables potentially deeper
approaches to mental phenomena. Dynamics of wide classes of complex systems
have been satisfactorily described within -statistics, a current
generalization of Boltzmann-Gibbs (BG) statistics. Here, we study human
electroencephalograms of typical human adults (EEG), very specifically their
inter-occurrence times across an arbitrarily chosen threshold of the signal
(observed, for instance, at the midparietal location in scalp). The
distributions of these inter-occurrence times differ from those usually
emerging within BG statistical mechanics. They are instead well approached
within the -statistical theory, based on non-additive entropies
characterized by the index . The present method points towards a suitable
tool for quantitatively accessing brain complexity, thus potentially opening
useful studies of the properties of both typical and altered brain physiology
