Recurrence Plot and Recurrence Quantification Analysis Techniques for Detecting a Critical Regime. Examples from Financial Market Indices
A. Fabretti, M. Ausloos
Recurrence Plot (RP) and Recurrence Quantification Analysis (RQA) are signal numerical analysis methodologies able to work with non linear dynamical systems and non stationarity. M…
Impact of saturation on spin effects in proton-proton scattering
O. V. Selyugin, J. R. Cudell
For pomerons described by a sum of two simple-pole terms, a soft and a hard pomeron, the unitarity bounds from saturation in impact-parameter space are examined. We consider the ef…
Saturation effects in pp scattering in the impact-parameter representation
O. V. Selyugin, J. R. Cudell
The impact of unitarity is considered in different approaches to saturation in impact-parameter space. The energy and momentum-transfer dependence of the total and differential cro…
Large-distance effects on spin observables at RHIC
O. V. Selyugin, J. R. Cudell, E. Predazzi
The impact of large-distance contributions on the behaviour of the slopes of the spin-non-flip and of the spin-flip amplitudes is analysed. It is shown that the long tail of the ha…
Notes on exotic anti-decuplet of baryons
M. V. Polyakov
We emphasize the importance of identifying non-exotic SU(3) partners of the Theta^+ pentaquark, and indicate possible ways how to do it. We also use the soliton picture of baryons…
Direct extraction of hadronic form factors from elastic-scattering data
E. Martynov, J. R. Cudell, A. Lengyel
Non-forward elastic hadron-scattering data are collected and analysed within the Regge approach. Through an analysis of the data in small bins in , we have directly extracted th…
