Energy dependence of the inelasticity in collisions from experimental information on charged particle multiplicity distributions
The dependence of the inelasticity in terms of the center of mass energy is
studied in the eikonal formalism, which provides connection between elastic and
inelastic channels. Due to the absence of inelasticity experimental datasets,
the present analysis is based on experimental information available on the full
phase space multiplicity distribution covering a large range of energy, namely
30 1800 GeV. Our results indicate that the decrease of
inelasticity is consequence of minijets production from semihard interactions
arising from the scattering of gluons carrying only a very small fractions of
the momenta from their parent protons. Alternative methods of estimating the
inelasticity are discussed and predictions to the LHC energies are presented
Multiparticle production in the model with antishadowing
We discuss the role of absorbtion and antishadowing in particle production.
We reproduce power-like energy behavior of the mean multiplicity in the model
with antishadowing and discuss physical implications of such behavior for the
hadron structure.Comment: 11 pages, 3 figures, extended version of the talk at the XXXII

Scaling violations: Connections between elastic and inelastic hadron scattering in a geometrical approach
Starting from a short range expansion of the inelastic overlap function,
capable of describing quite well the elastic pp and scattering data,
we obtain extensions to the inelastic channel, through unitarity and an impact
parameter approach. Based on geometrical arguments we infer some
characteristics of the elementary hadronic process and this allows an excellent
description of the inclusive multiplicity distributions in and
collisions. With this approach we quantitatively correlate the violations of
both geometrical and KNO scaling in an analytical way. The physical picture
from both channels is that the geometrical evolution of the hadronic
constituents is principally reponsible for the energy dependence of the
physical quantities rather than the dynamical (elementary) interaction itself.Comment: 16 pages, aps-revtex, 11 figure
A New Scheme for Calculation of the Multiplicity Distributions in Hadronic Interactions
We generalize an existing geometrical approach for multiparticle production in hadronic interactions, in which the overall multiplicity distribution is given by summing contributions coming from each impact parameter b of the incident hadronic system. In the previous work, the process occurring at a fixed impact parameter b was interpreted as due to an elementary collision with formation of an object similar to the one in e − e + annihilations. Here, we extend the model allowing the possibility of formation of more than just one string. The output seems to be more consistent with data
LESSONS FROM A LARGE DATASET OF AQUATIC ECOTOXICOLOGICAL TEST RESULTS FOR ROUTINE HP 14 CLASSIFICATION OF WASTES: THE CASE OF BOTTOM AND FLY ASHES IN THE ITALIAN FRAMEWORK
Anti-HIV-1 activities of 4 Telomerase Restrictors
MTT Cell Proliferation Assay was used to optimize the concentration of Telomerase Restrictors(TRs) with minimum toxicity to the selected cells. FACSort flow cytometer and Innotest P24 HIV(Human immunodeficiency Virus) antigen mAb ELISA Kit were used to investigate the anti-HIV-1 activities of TRs. The results showed that TRs had low cytotoxicity to the PBMC (Peripheral Blood mononuclear cells) and CEM/GFP if the concentration of TRs was at 50 \u3bcmol/L or below, and the supernatant from PBMC pretreated with SHIV and TR1-001 /TR1-002 could not infect the PBMC, while can infect the C8166 with reduced infectivity, which suggested that the TRs may be one of the novel resources for screening anti-HIV-1 agents
