In a previous paper, u we have shown that the Geometric Bremsstrahlung Model (GEM) is successful for the description of longitudinal momentum spectrum of the leading proton and the associated multiplicity distributions in the reaction PP->PX at 205 GeV/c. 2l Especially, 111 our model the smooth transitions from the eli ffractive to the nondiffracti ve regions in the spectrum are reproduced in c...

In the measurement of fast neutron multiplicity, multiplicity counting rates neutrons, including singles, doubles, and triplets, are often substituted into equation to solve quality problems. To simplify solution process directly obtain sample through S, D, T, a neural network multivariate nonlinear fitting used for analysis. First, multiple sets data measured detection system built with Geant4...

Hadron multiplicities in nucleus–nucleus interactions are calculated in the Dual Parton Model and its dependence on the number of collisions and the number of participants is analyzed. Shadowing corrections are calculated as a function of impact parameter and the multiplicity per participant as a funtion of centrality is found to be in agreement with experiment at SPS and RHIC energies. The obt...

Determination of temperature from experimental data has become important in searches for critical phenomena in heavy ion collisions. Widely used methods are ratios of isotopes (which rely on chemical and thermal equilibrium), population ratios of excited states etc. Using the lattice gas model we propose a new observable: nch/Z where nch is the charge multiplicity and Z is the charge of the fra...

Subthreshold events (pion production, for instance) at energies E < mπ are treated as rare events. The associated multiplicity distribution Pc(n) and the unconstrained distribution P (n), when there is no rare event-trigger, are related by the model independent relation Pc(n) = n2 〈n2〉 (n) . This relation, and in particular its improved version inspired in clustering of nucleons, is in fair agr...

We study the scattering on an ultra-low potential in zigzag graphene nanoribbon. Using a mathematical framework based on the continuous Dirac model and the augmented scattering matrix, we derive a condition for the existence of a trapped mode. We consider the threshold energies where the continuous spectrum changes its multiplicity and show that the trapped modes may appear for energies slightl...

We report the higher order cumulants and their ratios for baryon, charge and strangeness multiplicity in canonical and grand-canonical ensembles in ideal thermal model including all the resonances. When the number of conserved quanta is small, an explicit treatment of these conserved charges is required, which leads to a canonical description of the system and the fluctuations are significantly...

As an attempt to bridge between numerical analysis and algebraic geometry, this paper formulates the multiplicity for the general nonlinear system at an isolated zero, presents an algorithm for computing the multiplicity structure, proposes a depth-deflation method for accurate computation of multiple zeros, and introduces the basic algebraic theory of the multiplicity. Furthermore, this paper ...

Abstract This article deals with the existence, multiplicity, minimal complexity, and global structure of subharmonic solutions to a class planar Hamiltonian systems periodic coefficients, being classical predator-prey model V. Volterra its most paradigmatic example. By means topological approach based on techniques from bifurcation theory, first part paper ascertains their nature, multiplicity...
