Initial State Radiation: A success story
The investigation of events with Initial State Radiation (ISR) and subsequent
Radiative Return has become an impressively successful and guiding tool in low
and intermediate energy hadron physics with electron positron colliders: it
allows to measure hadronic cross sections and the ratio R from threshold up to
the maximum energy of the colliders running at fixed energy, to clarify
reaction mechanisms and reveal substructures (intermediate states and their
decay mechanisms) and to search for new highly excited mesonic states with
J^{PC} = 1^{--}. While being discussed since the sixties-seventies ISR became a
powerful tool for experimentalists only with the development of EVA-PHOKHARA, a
Monte Carlo generator developed over almost 10 years, while increasing its
complexity, which is user friendly, flexible and easy to implement into the
software of existing detectors.Comment: 6 pages, 2 figures, PHIPSI08 conferenc
Coherent production on nuclei and measurements of total cross sections for unstable particles
The Kölbig–Margolis formula is fitted to some explicitly nonperturbative models of diffractive production. It is shown that, in spite of the fact that the standard procedure of fitting the integrated cross sections may give acceptable fits, thus obtained "cross sections of unstable particles", , grossly disagree with the "true" cross sections known exactly from the models

How to Measure Chromo-magnetic Vacuum Background Field in , Hadron-Hadron and Nucleus-Nucleus Collisions
We propose a new type of the measurement which is sensitive to the QCD vacuum
color-magnetic fluctuations: A measure of the axial assymetry of the hadronic
final states produced in the high energy collisions is related to
the chromomagnetic vacuum field strength.Comment: 11 pages,latex,no figures,replaced,final version which takes into
account criticisms of referees of Phys.Rev. Title of the paper was changed.
The formula (14) was corrected, notation in formulae (12) and (13) changed.
Also we added forgotten vectorial notations,corrected misspellings and
improved the style and gramma
Extension and approximation of -subharmonic functions
Let be a bounded domain, and let be a
real-valued function defined on the whole topological boundary . The aim of this paper is to find a characterization of the functions
which can be extended to the inside to a -subharmonic function under
suitable assumptions on . We shall do so by using a function algebraic
approach with focus on -subharmonic functions defined on compact sets. We
end this note with some remarks on approximation of -subharmonic functions
Superscaling in dilute Fermi gas and its relation to general properties of the nucleon momentum distribution in nuclei
The superscaling observed in inclusive electron scattering is described
within the dilute Fermi gas model with interaction between the particles. The
comparison with the relativistic Fermi gas (RFG) model without interaction
shows an improvement in the explanation of the scaling function in
the region , where the RFG result is . It is found
that the behavior of for depends on the particular
form of the general power-law asymptotics of the momentum distribution
at large . The best agreement with the empirical
scaling function is found for in agreement with the asymptotics
of in the coherent density fluctuation model where . Thus,
superscaling gives information about the asymptotics of and the NN
forces.Comment: 6 pages, 5 figures, accepted for publication in Physical Review

First Order Static Excitation Potential: Scheme for Excitation Energies and Transition Moments
We present an approximation scheme for the calculation of the principal
excitation energies and transition moments of finite many-body systems. The
scheme is derived from a first order approximation to the self energy of a
recently proposed extended particle-hole Green's function. A hermitian
eigenvalue problem is encountered of the same size as the well-known Random
Phase Approximation (RPA). We find that it yields a size consistent description
of the excitation properties and removes an inconsistent treatment of the
ground state correlation by the RPA. By presenting a hermitian eigenvalue
problem the new scheme avoids the instabilities of the RPA and should be well
suited for large scale numerical calculations. These and additional properties
of the new approximation scheme are illuminated by a very simple exactly
solvable model.Comment: 15 pages revtex, 1 eps figure included, corrections in Eq. (A1) and

Determination of Matter Surface Distribution of Neutron-rich Nuclei
We demonstrate that the matter density distribution in the surface region is
determined well by the use of the relatively low-intensity beams that become
available at the upcoming radioactive beam facilities. Following the method
used in the analyses of electron scattering, we examine how well the density
distribution is determined in a model-independent way by generating pseudo data
and by carefully applying statistical and systematic error analyses. We also
study how the determination becomes deteriorated in the central region of the
density, as the quality of data decreases. Determination of the density
distributions of neutron-rich nuclei is performed by fixing parameters in the
basis functions to the neighboring stable nuclei. The procedure allows that the
knowledge of the density distributions of stable nuclei assists to strengthen
the determination of their unstable isotopes.Comment: 41 pages, latex, 27 figure
