Perturbative and non-perturbative effects in ultraperipheral production of lepton pairs
I. M. Dremin
Perturbative and non-perturbative terms of the cross sections of ultraperipheral production of lepton pairs in ion collisions are taken into account. It is shown that production of…
Positronia' clouds in Universe
I. M. Dremin
The intense emission of 511 keV photons from the Galactic center and within terrestrial thunderstorms is attributed to the formation of parapositronia' clouds. Unbound electron-pos…
Enhancement of low-mass dileptons in ultraperipheral collisions
I. M. Dremin, S. R. Gevorkyan, D. T. Madigozhin
It is shown that production of low-mass -pairs in ultraperipheral nuclear collisions is enhanced due to the Sommerfeld-Gamow-Sakharov (SGS) factor. This effect is especiall…
Excess of soft dielectrons and photons
I. M. Dremin
Spectra of unbound electron-positron pairs (dielectrons, in brief) and photons from decays of parapositronia produced in ultraperipheral collisions of electrically charged objects…
Ultraperipheral nuclear interactions
I. M. Dremin
Large-distance ultraperipheral collisions of two relativistic ions are considered. The clouds of photons surrounding the ions are responsible for their distant electromagnetic inte…
The multilayer structure of protons
I. M. Dremin
It is argued that the dynamics of the elastic scattering of high-energy protons at intermediate transferred momenta changes with the energy increase. It evolves from the multiple s…
Central and peripheral interactions of hadrons
I. M. Dremin, V. A. Nechitailo, S. N. White
Surprisingly enough, the ratio of elastic to inelastic cross sections of proton interactions increases with energy in the interval correspond- ing to ISR - LHC (i.e. from 10 GeV to…
A toy model of elastic scattering of high energy protons
I. M. Dremin
The ratio of elastic to total proton cross sections is related to the darkness of the spatial profile of inelastic interactions by a single parameter in the framework of a simple a…
Unexpected properties of interactions of high energy protons
I. M. Dremin
Experimental data on proton-proton interactions in high energy collisions show quite a special and unexpected behaviour of the proportion of elastic scattering compared to inelasti…
Critical behavior of cross sections at LHC
I. M. Dremin
Recent experimental data on elastic scattering of high energy protons show that the critical regime has been reached at LHC energies. The approach to criticality is demonstrated by…
Asymmetric vector mesons produced in nuclear collisions
I. M. Dremin, V. A. Nechitailo
It is argued that the experimentally observed phenomenon of asymmetric shapes of vector mesons produced in nuclear media during high energy nucleus-nucleus collisions can be explai…
Will protons become gray at 13 TeV and 100 TeV?
I. M. Dremin
It is shown that the regime of pp-interactions at 7 TeV is a critical one. The LHC data about elastic pp-scattering at 7 and 8 TeV are used to get some information about both elast…
The robust impact parameter profile of inelastic collisions
I. M. Dremin
It is shown that the impact parameter profile of inelastic hadron collisions is robust to admissible variations of the shape of the diffraction cone of elastic scattering. This con…
The interaction region of high energy protons
I. M. Dremin
New experimental data about proton-proton collisions obtained atthe LHC allow to widen strongly the energy interval where one gets some knowledge about the structure of their inter…
Torus or black disk?
I. M. Dremin
We show that the interaction region of colliding protons looks completely absorptive (black) at the impact parameters up to 0.4 - 0.5 fm at the LHC energy 7 TeV. It is governed by…
The critical regime of elastic scattering of protons at the LHC
I. M. Dremin
It is shown that the darkness of the interaction region of protons is governed by the ratio of the slope of the diffraction cone to the total cross section. At LHC energies, it bec…
Jets in multiparticle production in and beyond geometry of proton-proton collisions at the LHC
M. Yu. Azarkin, I. M. Dremin, M. Strikman
Experimental findings of CMS on properties of jets and underlying events at high multiplicities in proton-proton interactions at 7 TeV are interpreted as an indication of increasin…
Hadron structure and elastic scattering
I. M. Dremin
When colliding, the high energy hadrons can either produce new particles or scatter elastically without change of their quantum numbers and other particles produced. Namely elastic…
Proton periphery activated by multiparticle dynamics
I. M. Dremin, V. A. Nechitailo
It is shown that protons become more active at the periphery with increase of their collision energy. By computing the impact parameter distribution of the proton-proton overlap fu…
Interplay of total cross sections and ratios of real to imaginary parts of hadron amplitudes

I. M. Dremin, V. A. Nechitailo
Theoretical proposals of scaling laws for the differential elastic scattering cross sections of protons are confronted with experimental data over a wide energy range. Different co…
Scaling laws for the elastic scattering amplitude
I. M. Dremin, A. A. Radovskaya
The partial differential equation for the imaginary part of the elastic scattering amplitude is derived. It is solved in the black disk limit. The asymptotical scaling behavior of…

The s-channel unitarity condition for the imaginary part of the hadronic elastic scattering amplitude outside the diffraction peak is studied within different assumptions about the…
Elastic scattering of hadrons
I. M. Dremin
Colliding high energy hadrons either produce new particles or scatter elastically with their quantum numbers conserved and no other particles produced. We consider the latter case…
